After releasing some projects with the ESP32-CAM, some readers reported issues when trying to use the ESP32-CAM. This guide is a compilation with the most common errors when using the ESP32-CAM and how to fix them.
We’ve released the following projects with the ESP32-CAM:
- Video Streaming, Face Detection and Face Recognition
- ESP32 IP CAM – Video Streaming (Home Assistant and Node-RED)
- Take Photo and Save to MicroSD Card
- PIR Motion Detector with Photo Capture
- Take Photo, Save to SPIFFS and Display in Web Server
Note: some of our readers reported errors when trying to follow the ESP32-CAM project with Home Assistant. We’ve modified some lines on the code, so most of the problems related with that project should be fixed.
Please note that we couldn’t reproduce some of the errors on our end. However, we’ve gathered all the information given by our readers to get answers to the most common issues.
If you have a different problem or a different solution to these issues, you can share your tips by writing a comment below.
Most common errors:
- Failed to connect to ESP32: Timed out waiting for packet header
- Camera init failed with error 0x20001 or similar
- Brownout detector or Guru meditation error
- Sketch too big error – Wrong partition scheme selected
- Board at COMX is not available – COM Port Not Selected
- Psram error: GPIO isr service is not installed
- Weak Wi-Fi Signal
- No IP Address in Arduino IDE Serial Monitor
- Can’t open web server
- The image lags/shows lots of latency
- esp_camera_fb_get(): Failed to get the frame on time!
1. Failed to connect to ESP32: Timed out waiting for packet header
This error means that the ESP32-CAM is not in flashing mode or it is not connected properly to the FTDI programmer.
Double-check the steps to upload code
Double-check that you’ve followed the exact steps to put your ESP32-CAM in flashing mode. Failing to complete one of the steps may result in that error. Here’s the steps you need to follow:
Connect the ESP32-CAM board to your computer using an FTDI programmer. Follow the next schematic diagram:
Important: GPIO 0 needs to be connected to GND so that you’re able to upload code.
Many FTDI programmers have a jumper that allows you to select 3.3V or 5V. Make sure the jumper is in the right place to select 5V.
Important: GPIO 0 needs to be connected to GND so that you’re able to upload code.
| ESP32-CAM | FTDI Programmer |
| GND | GND |
| 5V | VCC (5V) |
| U0R | TX |
| U0T | RX |
| GPIO 0 | GND |
To upload the code, follow the next steps:
1) Go to Tools > Board and select AI-Thinker ESP32-CAM.
2) Go to Tools > Port and select the COM port the ESP32 is connected to.
3) Then, click the upload button to upload the code.
4) When you start to see these dots on the debugging window as shown below, press the ESP32-CAM on-board RST button.
After a few seconds, the code should be successfully uploaded to your board.
GPIO 0 must be connected to GND
Important: if you can’t upload the code, double-check that GPIO 0 is connected to GND and that you selected the right settings in the Tools menu. You should also press the on-board Reset button to restart your ESP32 in flashing mode. Also, check that you have the FTDI programmer jumper cap set to 5V.
Check the FTDI programmer you are using
One of our readers reported the following: “found out that you can program the board with a USB-to-TTL module model CP2102 and that the CH340 model does NOT work“. This is the FTDI programmer we’re using.
Power the ESP32-CAM with 5V
Some of our readers reported that they could only upload code when the ESP32 was powered with 5V. So, power the ESP32-CAM with 5V.
FTDI Programmer 5V
Measure the output voltage of your FTDI programmer (VCC and GND) using a Multimeter to ensure it’s providing 5V to your ESP32-CAM.
2. Camera init failed with error 0x20001 or similar
If you get this exact error, it means that your camera OVX is not connected properly to your ESP32 board or you have the wrong pin assignment in the code.
Sometimes, unplugging and plugging the FTDI programmer multiple times or restart the board multiple times, might solve the issue.
Camera not connected properly
The camera has a tiny connector and you must ensure it’s connected in the the right away and with a secure fit, otherwise it will fail to establish a connection.
Wrong pin assignment in the code
When you get this error, it might also mean that you didn’t select the right board in the define section or the pin definition is wrong for your board.
Make sure you select the right camera module in your projects. You just need to uncomment the right camera module and comment all the others:
//#define CAMERA_MODEL_WROVER_KIT
//#define CAMERA_MODEL_M5STACK_PSRAM
#define CAMERA_MODEL_AI_THINKERIn this example, we’re using the CAMERA_MODEL_AI_THINKER, so it’s the one that is enabled. Otherwise, it will fail the pin assignment and the camera will fail to init.
There are many esp32-cam boards being released (“fake boards”) that the wiring between the ESP32 and the OV camera might be different, so selecting the camera module, might not be enough. You might need to check each gpio declaration with your board pinout.
For example, M5Stack board without PSRAM has a different pin assignment than the M5STACK with PSRAM (defined on the code by default). So, you need to change the pin definition in the code accordingly to the board pinout.
Not enough power through USB source
If you’re powering your ESP32 through a USB port on your computer, it might not be supplying enough power.
Faulty FTDI programmer
Some readers also reported this problem was solved by replacing their actual FTDI programmer with this one.
The camera/connector is broken
If you get this error, it might also mean that your camera or the camera ribbon is broken. If that is the case, you may get a new OV2640 camera probe.
3. Brownout detector or Guru meditation error
When you open your Arduino IDE Serial monitor and the error message “Brownout detector was triggered” is constantly being printed over and over again. It means that there’s some sort of hardware problem.
It’s often related to one of the following issues:
- Poor quality USB cable;
- USB cable is too long;
- Board with some defect (bad solder joints);
- Bad computer USB port;
- Or not enough power provided by the computer USB port.
Solution:
- try a different shorter USB cable (with data wires)
- use a different computer USB port or use a USB hub with an external power supply
- some readers reported that when powering the ESP32-CAM with 5V, the issue was fixed.
Also, follow the suggestions described in issue 2.
4. Sketch too big error – Wrong partition scheme selected
When you get the following error:
Sketch too big; see http://www.arduino.cc/en/Guide/Troubleshooting#size for tips on reducing it.
Error compiling for board ESP32 Dev Module.It means that you haven’t selected the right partition scheme. Make sure you select the right partition scheme. In your Arduino IDE, go to Tools > Partition Scheme, select “Huge APP (3MB No OTA)“.
5. Board at COMX is not available – COM Port Not Selected
If you get the following error or similar:
serial.serialutil.SerialException: could not open port 'COM8': WindowsError(2, 'The system cannot find the file specified.')
Failed to execute script esptool
the selected serial port Failed to execute script esptool
does not exist or your board is not connected
Board at COM8 is not availableIt means that you haven’t selected the COM port in the Tools menu. In your Arduino IDE, go to Tools > Port and select the COM port the ESP32 is connected to.
It might also mean that the ESP32-CAM is not establishing a serial connection with your computer or it is not properly connected to the USB connector.
6. Psram error: GPIO isr service is not installed
You are using a board without PSRAM and you get the following error or similar:
E (161) gpio: gpio_isr_handler_remove(380): GPIO isr service is not installed, call gpio_install_isr_service() first
Camera init failed with error 0x101when the board was initialized with the following settings:
config.frame_size = FRAMESIZE_UXGA;
config.jpeg_quality = 10;
config.fb_count = 2;Adding the following fixes the issues (it lowers the image resolution so it won’t need so much space to store images. However, as a result, you cannot get some high resolution formats due to the limited memory):
if(psramFound()){
config.frame_size = FRAMESIZE_UXGA;
config.jpeg_quality = 10;
config.fb_count = 2;
} else {
config.frame_size = FRAMESIZE_SVGA;
config.jpeg_quality = 12;
config.fb_count = 1;
}Note: face recognition and detection doesn’t work with boards without PSRAM. However, you can still use all the other functionalities of the board. For example, although you can’t use the face recognition and detection features of this project (ESP32-CAM Video Streaming and Face Recognition with Arduino IDE), you can still play with the example and explore the board features as long as you have the right pin assignment in the code.
7. Weak Wi-Fi Signal
Some readers reported that after powering the ESP32-CAM with 5V, they’ve gotten a more stable Wi-Fi signal. You can read this dedicated guide to learn how to connect an external antenna to the ESP32-CAM and extend Wi-Fi coverage.
The ESP32-CAM has the option to use either the built-in antenna or an external antenna. If your ESP32-CAM AI-Thinker has no Wi-Fi connection or poor connection, it might have the external antenna enabled. If you connect an external antenna to the connector, it should work fine.
Check if the jumper 0K resistor by the antenna connector is in the proper position for the desired antenna. There are 3 little white squares laid out like a “<” with the middle position being common.
The following photo shows a closer look at that area. You can clearly see a small 0K resistor connecting to the built-in antenna.
With board turned so the the PCB antenna is up:
- To use the PCB antenna, the resistor must be on the top position, like this: /
- For the antenna connector, the resistor must be on the bottom position, like this: \
So, to enable the on-board antenna:
- Unsolder the resistor that goes to the antenna, it’s in this position \
- And solder together the two connections to enable the on-board antenna.
8. No IP Address in Arduino IDE Serial Monitor
f you just see dots printed in the serial monitor (……), it means that your ESP32-CAM is not establishing a Wi-Fi connection with your router.
Double-check your network credentials
You need to make sure that you’ve typed your exact network credentials (SSID and password) in the following variables:
const char* ssid = "REPLACE_WITH_YOUR_SSID";
const char* password = "REPLACE_WITH_YOUR_PASSWORD";Select the right baud rate in the Arduino IDE Serial Monitor
If you don’t select the right baud rate in the Arduino IDE Serial Monitor, you won’t get your board IP address or you’ll just get garbage on the screen.
Make sure you select the right baud rate. In our examples with the ESP32-CAM, we use 115200 baud rate.
Reset the board multiple times
You might also need to press the ESP32-CAM on-board RESET button multiple times to restart your ESP and print the IP address during boot.
RX and TX swapped
Double-check the connections between your ESP32 board and the FTDI programmer. RX goes to TX and TX goes to RX. If these connections are swapped, the ESP32-CAM is not able to establish a serial communication with your computer.
Wi-Fi Range
If the router is far away from your ESP32 board, it might not be able to catch the Wi-Fi signal. Ensure that your ESP32-CAM is fairly close to your router.
9. Can’t open web server
If the ESP32-CAM is printing the IP address in your Arduino IDE Serial Monitor, but when you try to open the web server in your web browser you see a blank screen, it usually means that you are trying to access the ESP32-CAM web server with multiple web browser tabs.
At the moment, these ESP32-CAM sketches only work with one client connected at a time.
10. The image lags/shows lots of latency
Having some latency is normal for such a small and cheap camera. Some readers have suggested the following to reduce latency:
- Power the ESP32-CAM with a standalone 5V power supply
- Reduce the frame size with the following in your code:
config.frame_size = FRAMESIZE_SVGA or config.frame_size = FRAMESIZE_VGA - Use an external antenna.
11. esp_camera_fb_get(): Failed to get the frame on time!
We’ve personally never faced this issue. However, many readers are getting this error with their ESP32-CAM boards.
One of our readers (Fibula) suggested the following to solve this issue:
“Im using the ESP32-CAM Module 2MP OV2640 Camera sensor Module Type-C USB module from Aliexpress. Although not mentioned, It doesn’t have the extra PSRAM the other M5 models do, and the camera has one changed IO pin.
See here: https://github.com/m5stack/m5stack-cam-psram/blob/master/README.md and scroll down to Interface Comparison.
The CameraWebServer Arduino example we’re probably all using doesn’t have this ESP32-CAM model defined.
You need to add it yourself in the main tab add:
#define CAMERA_MODEL_M5STACK_NO_PSRAMAnd in the camera_pins.h tab add the following:
#elif defined(CAMERA_MODEL_M5STACK_NO_PSRAM)
#define PWDN_GPIO_NUM -1
#define RESET_GPIO_NUM 15
#define XCLK_GPIO_NUM 27
#define SIOD_GPIO_NUM 25
#define SIOC_GPIO_NUM 23
#define Y9_GPIO_NUM 19
#define Y8_GPIO_NUM 36
#define Y7_GPIO_NUM 18
#define Y6_GPIO_NUM 39
#define Y5_GPIO_NUM 5
#define Y4_GPIO_NUM 34
#define Y3_GPIO_NUM 35
#define Y2_GPIO_NUM 17
#define VSYNC_GPIO_NUM 22
#define HREF_GPIO_NUM 26
#define PCLK_GPIO_NUM 21And you’re good to go.
Also note that the max resolution of the bare ESP32-CAM Module is XGA 1024×768, I assume also because of the lack of PSRAM. “
We hope this suggestion solves your issue. Let us know in the comments section.
Using larger microSD card sizes
According to he datasheet, the ESP32-CAM should only supports 4GB microSD cards.
However, we’ve tested with 16GB microSD card and it works well.
You might not be able to store more than 4GB, even though you have 16GB. We haven’t tested storing more than 4GB, so we’re not sure about this.
Are these projects compatible with M5Stack board?
Yes, the M5Stack ESP32 board is compatible with out projects. However, you must check your camera pinout to ensure you have the right assignment in the code.
You can check the M5Stack camera connections here.
How to set a fixed the IP Address
To set a static/fixed IP address, you can follow the next tutorial:
Setting ESP32-CAM as Access Point (AP)
You can set your ESP32-CAM as an Access Point (AP). This means you are able to connect to your ESP32-CAM directly without having to connect to your router. You can use the following code to set your video streaming web server as an Access Point:

Sara. I keep getting an error while compiling with dl_lib.h.
I am also unable to find that file on the web. Can you please enlighten me
on how to find that file.

just comment the line
#include “dl_lib.h”

can you check if video streaming function well , changing the port .
Yes, you can change the Port and it will work. I’ve tried it
Mine runs for a few minutes and then starts showing fragmented frames and then dies.
I followed the direction correctly and the code gives me an IP address. When I enter the IP address I get the web page but no image. I am using 5v power as 3.3 v would not work. I have seen other people with this problem but no answers on what causes this or how to fix it.
Got mine working using an external 3.3V supply (brownout if I tried to use USB power) and using Firefox on Win10 to connect. If I try to connect from a mobile device (Android phone or old iPad) I see the webcam menu but I don’t see the image. Troubleshooting guide suggests no image with multiple web clients, but this was single client connection.
I also get an error “dl_lib.h: No such file or directory”
Then i have downloaded the file “dl_lib.h” from :
https://github.com/denizyuret/dlib/blob/master/dlib.h
.. but then i got another error :

Hello you missed that the most common reason for brown outs are to thin cables
That can also be the issue.
Thanks for sharing 🙂
WEAK SIGNAL is also cause by the jumper that is solded for use the external antenna. Just change it to use the internal antenna
Hi Mario.
Thanks for pointing that out.
We’ll update the guide with that information.
You also need to put information on the page about setting the jumper on the FTDI board.
The other thing I see is and especially people that pay for your projects that you do not provide the help you should.
Kevin,
I find just the opposite. Rui and Sara help extensively. I do not get why you would think that at all? You do have to take some initiative to solve your own problems, but the computer systems, browsers, board possibilities and mis-understandings abound, so I find they do a very good job of support whenever possible.
Sorry you don’t think so.
Dave
Hi Sara/Rui
While trying to run the esp32 camera sketch using the FTDI device to interface the ESP32-CAM module to my PC I get the following error despite using the correct COM port using the Arduino IDE.
esptool.py v2.6
Serial port COM3
Traceback (most recent call last):

do you have a solution to this problem as I have followed your advice on the esp32-cam-troubeshooting-guide.
Thank you.
It looks like your COM port is open or being used in another program. Make sure you close all the programs that use COM ports (you might also need to close the Arduino IDE serial monitor).
Also, have the same issue, the port option is grayed out for me.
I get the same error.
Were you able to resolve it?
Were you able to resolve it?
No matter what I do, every time I try to connect to the server, I get the following message in the browser:
“Header fields are too long for server to interpret”
I have tried several sketches, several fixes, several apparent workarounds, but it just keeps coming up. It compiles and uploads without a problem. But this issue is stopping any further progress.
Any ideas would be greatly appreciated.
J.
Any luck?
I get the same error: “Header fields are too long for server to interpret”
It seams that the browser sends too many headers that cannot be processed by ESP32.
From the internet (not the local network) this happens with chrome, but it shows OK if I choose incognito mode.
It shows OK in LAN.
I’m using ARDUINO IDE.
I read this but could not solve the issue: github.com/espressif/arduino-esp32/issues/2983
Does ESP32-CAM work with OTA Update?
I haven’t tried it, but it will depend if your sketch that is running has enough memory left to use OTA…
Thank you for publishing this informative and very helpful troubleshooting guide. Specifically for the TTGO T-Camera w/Microphone v1.6, courtesy of github.com/lewisxhe/esp32-camera-series we learned you MUST set PinMode on GPIO 13 and 14:
pinMode(13, INPUT_PULLUP);
pinMode(14, INPUT_PULLUP);
to prevent crashes.
Thanks for the info, I’ve never used that board, but it’s good to know.

Hello,
That doesn’t look like an error. It simply looks like the debugging information that is printed in your serial monitor after restarting your board.
Hello,
I am experiencing the same error with the person that you’ve gave this reply. I can upload the cameraeserver example code to ESP32Cam without a problem. My network credentials are correct, but when i go to the serial monitor i only view the debugging information :

I am experiencing the exact same situation. Have you find any solutions ?
Yes! Finally got it to work. What worked for me was first flashing at 3V3 and then running the ESP32 at 5V. However, one thing I missed, even in the troubleshooting guide (and did wrong myself) was that after switching to 5V, you will also have to connect the Vcc line (now carrying 5V) to the 5V pin on the ESP32 board in stead of the 3V3 pin that is only used for flashing. This may be obvious for experienced ESP32 users, but it isn’t for everyone 😉
Hi Pierre.
I’m happy that you finally made it work!
Thank you for sharing your mistakes. It may be helpful for some of our readers.
Now you can have fun experimenting our ESP32-CAM projects 😀
Regards,
Sara
That worked for me!
Thank you Pierre!
Hi. I did not understand the solution. I have the esp32cam, with AI thinker camera. In programming mode I put gnd with io0. With camera and wifi it doesn’t throw errors, but if I add a PIR am312, with “attachInterrupt” it returns an error: rst: 0x1 (POWERON_RESET), boot: 0x13 (SPI_FAST_FLASH_BOOT). It gave you this error and how did you solve it? Thank you.
I have tried it with 5v, with 3v. but something is missing right?
Hi.
With the ESP32-CAM you can’t use the attachInterrupt() function when using the camera.
You must set the interrupt as follows:
err = gpio_isr_handler_add(GPIO_NUM_13, &detectsMovement, (void *) 13);
if (err != ESP_OK) {
Serial.printf(“handler add failed with error 0x%x \r\n”, err);
}
err = gpio_set_intr_type(GPIO_NUM_13, GPIO_INTR_POSEDGE);
if (err != ESP_OK) {
Serial.printf(“set intr type failed with error 0x%x \r\n”, err);
}
Don’t forget to create the callback function:
static void IRAM_ATTR detectsMovement(void * arg) {
motionDetected = true;
}
I hope this helps.

Sara
I can connect to web page get everything but no video, l am monitoring the output of the board an it is sending packets. Tried several browsers with same result also tried several esp boards and cameras.H E L P!!!
Frustrated
Hi.
I understand your frustration.
However, without any additional details, it is very difficult to understand what is causing the issue…
camera streams fine on my android chrome browser, however in Microsoft edge its just an x but it will capture a still. one thing I notice is when the button start stream is depressed looking in serial monitor nothing happens. its like the start stream button has no functionality . could be a flash issue or some other html issue.
Hi.
I think it’s a problem with the HTML. I think some features are not supported on Edge.
Regards,
Sara
Rui
The camera I have is the one that seems to be on most of the ebay sites ie ESP32-S FCCID 2AHMR. I haven’t been able to buy an AI Thinker esp32cam.
Sketch downloads for mine but when you go to serial monitor it says camera not supported.
Do you know if there is any camera model you can select for the sketch that will make this work?
I always bought my ESP32-CAM from Banggood and they all worked for me…
Mine is the same as yours but the AI Thinker works fine anyway. You have probably figured this by now but maybe will help others.
Sara, please help, I have the esp32 cam programed ,I can connect to it with 4 different browsers, powered it with both 3.3 and 5 volts on the respected pins, I see packets being transmitted but no video image . I see this on two different boards and cameras ,do you have any ideas?
Hi.
Are you powering the ESP32-CAM with 5V and 3.3V simultaneously? You should only use one power source.
Were you able to see the streaming when just one web browser tab with the streaming is open? (just one client at a time)?
Regards,
Sara
Only one voltage source at a time not both, and only one session at at time one on each browser at a time no multi sessions. Each session was monitored from the esp. I have tried several video modes from the web page configuration and restarted the session. If I could send you an image it would be worth a thousand words.
Hi Frank.
What web browser are you using?
You can upload your photo to imgur, google drive or other, and then share the link.
Regards,
Sara
Dear Rui/Sara
Forget my previous comment. Finally got it to work by
1. Getting hold of AIThinker ESP32 -S
2. Getting a secure camera connection (previous camera/ESP32 did not connect securely and camera kept falling out.
3.Using a CP2102 and connecting ESP32-S to 5v

Hi Neil.
I’m glad that your problem is now fixed.
Thank you for sharing.

Sara
Hi,
thanks for the fine tutorial and this troubleshooting guide!
I followed the steps and everything compiled, uploaded, started. The Serial monitor notifies that webserver at port 80 and stream server at port 81 have started and the Camera ready – however, I can only see the settings and get a black rectangle instead of the video. 2 or 3 other posters may have the same problem.
The hardware was bought from and is described at:
aliexpress.com/item/33038740493.html?spm=a2g0s.9042311.0.0.4cfd4c4d39A7TQ
Is there anything I can contribute to research the problem?
Hi Danyel.
Thank you for sharing your problem.
Some readers have reported same problem as you. However, if you already followed all our suggestion in our troubleshooting guide, I don’t know what else can be the problem.
Some people reported that after powering the ESP32 with 5V, everything started working fine.
Regards,
Sara
Danyel, Sara,
I did have the same problem with one of my modules. The module seemed to work, but was showing just an empty black frame with the red cross in the upper right corner.
After some investigation with a magnifier glass, I found that Pins GND, GPIO23 and GPIO22 of the WROOM module (the pins close to the antenna connector) did have no solder or better said, not enough solder to bridge a connection. After resoldering these three, the module worked.
Hope this is of help to anyone.
Regards
Frank
Thanks for sharing that.
I didn’t know that was an issue.

Hi,
I have programed mine with both sketches (not at the same time). After using 5v for programing all seemed to go well.
However, regardless of which sketch (server or other) the images is full of horizontal lines. I have also noticed that the EPS32 module AND camera module get very hot after just a few minutes.
This is regardless of 5v or 3.3volts.
I have tried running off a battery in case the lines are generated by noise from a USB supply, but there is no difference.
Has anyone else had this or do you have any ideas.
Thanks.
Hi Martin.
For what you describe it seems that your camera may be defective or broken.
Do you get any errors in the Serial Monitor regarding the camera initialization?
Regards,
Sara
I have same issue, bought two modules twice from two different sellers and tested with both sketches and with both camera modules straight and with interchanged boards along with all available 5V, 1.5Amp & 2Amp chargers (even used filter capacitor as well), with programmable power supply and even directly with 2200mA battery but unable to remove the colored horizontal lines overlapping video. Now there are only two possibilities, either it is a design fault from the manufacturer’s end or there is something required to be modified in sketch code!
Hello, the problem is related to wifi power transmission (interference?). If the power transmission is reduced the lines disappear.
brownout and camera init failed whatever I tried every camera model and every troubleshooting guide as above.. Then I found someone said esp32 should connect 5v rather than 3.3v. Finally it works after I connect to 5v to eps32!

I’ve tried to connected the ESP32-CAM to Homeassiatnt without success.
Streaming to web app (ie ,chrom,saphari) works fine.
I’ve done clean install of homeassistant on my Ubuntu laptop.
No other devices expect the camera. Still with no results. Working with 5V coming from the USB slot to power the camera.
I suspect the camera code , although full success is reported at HA forums.
Looking for an advice.
Have the same problem: dl_lib.h not found. Cant find the library. Can you tell us where to find it?
Kind regards and greetings from Switzerland
delf
I got my camera working perfectly but face recognition will not work. There have been some comments floating around that the problem is with version 1.0.2 of the library. Can you confirm this is the cause of the problem.
Cheers
Neil Austen
Hi, Neil, happy new year! I have encountered the same problem as you. Now my online video stream works normally, but when I clicked the “Face recognition” and “Face Detection”, nothing happened and there is no colorful box displayed.
Besides, my board has also PSRAM. I still don’t know how to solve it? Do you have any progress on this problem?
Team,
I spent a lot of time trying to fix the issue #3 (Brownout… and Guru Meditation –> Amiga style) and the problem was on the Chinese USB-to-RS323 TTL module. I think those does not work well at high baud data communication, failing to transmit data to ESP32. I did change to a new module (original FTDI) and works perfectly.
Hope it helps,
AH
Hi Alvaro,
Thanks for sharing that.
Regards,
Sara
THANK YOU SO MUCH
I had this problem for so long and you helped me
first of all congratulations for these wonderful tutorials of esp32-cam..really high quality stuff..
after 1-2 hours with Brownout detector error..and after trying change to another cable or usb port or try usb hub nothing worked..
a test i suggest to other users is to upload an easy sketch like:
void setup(){ Serial.begin(115200);} void loop(){Serial.println(“i’m working”);}
if you open serial..you MUST see the message..
BUT when i tried some “heavy” sketch like WiFi scan example..or the CameraWebServer i had the Brownout detector error..
The only solution i found until now is to use a good power supply with 5v. Then i disconnected 5v (or 3.3v) pin that connects ESP and FTDI and connect the 5v ESP pin to the power supply, and the ground with the ground of ESP (i left the ESP32-FTDI ground because i guess everything has to be grounded).
After that reupload camera sketch and everything worked perfect..
So, i guess Wifi is very hungry for power to run with a USB..
btw..i have a question that nowhere have found good solid answer:
on ESP32-CAM there is 5v, 3.3v and VCC pins..
5v and 3.3v is only for INPUT to esp? can also work as OUTPUT?
what is VCC and what if i want to power ESP with a 9V battery?
Sorry..for the ultra long post..
First, thanks for providing so much great info about the ESP32 camera :-). To chime in regarding my experiences.
1. using the FTDI adaptor VCC pin to provide power produces brownouts, so I use a good 5V supply to the 5V pin on the module. The Vcc pin on the module is “not” connected to external power, and shows 3.3V.
2. I bought modules from 2 different ebay vendors, the first would not flash, no matter what, but the 2nd works fine, with both Rui’s code and the ESP32/camera example in the Arduino IDE.
3. it always pays to try a simple program first, like toggling an I/O pin, just to see if the module will flash ok.
my problem is esp32 was working correctly i was de bugging codes one time message came esp32 wroom is not recognised,after that whole day i was trying but no luck , i re installed arduino ide esspressif, no luck no error message, it says Hash data varified , Compressed 3072 bytes to 144… , writing at 0x00008000…..(100%)

Hi.
That message means that the code was successfully uploaded to your board.
After seeing that message, press the on-board RST button to start the program.

Hi.
Please double-check that your serial monitor is set at a baud rate of 115200 and that you have the right RX and TX connections.
Regards,

Small adjustment to Sara’s reply.
…..
After seeing that message, REMOVE the jumper/link between IO0 and GND and THEN press the RST (reset) button. 🙂
By the way, was the jumper/link connected between IO0 and GND before sketch upload?

Hey, I have been eating my heart out in finding the solution to this error. I have also looked into other forums for this answer if anyone faced the same issue but none seem to be giving any solid way to correct this problem.
I have also installed cp210x driver that did not work either.
Even did the pip installation of pyserial as was given in one of the forums
Please, I would really appreciate if you could help me in on this.

Hi Sanil.
I think that error means that your computer is not able to find your ESP32-CAM.
It may not be properly connected to your FTDI programmer, or you may not be using a proper data cable.
Your computer may not be able to provide enough current, or you might need to power the ESP32-CAM with 5V.
Which FTDI programmer are you using?
Take a look at this, it may also help: https://github.com/espressif/arduino-esp32/issues/1137#issuecomment-367960948

I can not get an IP address in the monitor window. I get all other info except the ip address. I have made sure my ssid and password for my wifi is correct. Is there suppose to be any info come up in the monitor window to tell me if something is wrong?
Any suggestions?
There are a few posts here with no answers to the issue of “dl_lib.h: No such file or directory” when compiling. Some have said just commenting it out will allow you to compile, which is true, but I’m not getting an image. Is there no answer to the issue of the missing library file? The other example tutorial for streaming works fine.
Hi.
At the moment, we still haven’t figured out what the problem is :/
If anyone knows how to solve this, please share.
Regards,
Sara
dl_lib.h: No such file or directory
For dl_lib.h: No such file or directory is because ESP32 Board Version 1.03 does’nt seem to include this anymore. Downgrade your ESP32 Board Version down to 1.02 in Andruino IDE and it should be fine. Worked for me.
Thanks for sharing 😀
This did it for me too!
You have to use new example file from 1.04 – there is a change in a program code.
for those who are facing the compilation error: dl_lib.h: No such file or directory, just comment out the #include”dl_lib.h” and it should get compiled. (ESP32 code 1.03).
Good morning

“Failed to connect to ESP32: Timed out waiting for packet header”. Add me to the people who failed to download the ESP32-CAM sketch when I connected the FTDI 3.3v output to 3v3 on the ESP32-CAM, using a genuine FTDI FT232RL-based USB serial adapter.
I resolved by switching the FTDI adapter to 5v mode, and connecting from the Vcc output on FTDI to the 5v input on the ESP32.
I note that you show the connection made this way in your PIR project blog post. https://i2.wp.com/randomnerdtutorials.com/wp-content/uploads/2019/08/ESP32-CAM-FTDI-programmer-5V-supply.png
Hi Rob.
Yes, you are right.
We can get our ESP32-CAM working with 3.3V.
However, after so many issues reported by ours readers, we now recommend powering with 5V on our most recent projects.
We still need to update some of our previous ESP32-CAM projects to use 5V instead of 3.3V.
Thanks for sharing.

Im using the ESP32-CAM Module 2MP OV2640 Camera sensor Module Type-C USB module from Aliexpress.

#define HREF_GPIO_NUM 26
#define PCLK_GPIO_NUM 21
And you’re good to go.
Also note that the max resolution of the bare ESP32-CAM Module is XGA1024x768 i assume also because of the lack of PSRAM.
Hi.
Thanks for sharing.
I’ll add this to our troubleshooting guide.
I’ve never faced this issue though. However, many people are complaining about this error.

Sara
Fibula, thanks for the info, although I am not using the M5STACK module. Therefore, this info does not apply and does not resolve the issue for me. I still get this error. Based on your information, the likely cause is similar and likely caused by a pin change. The search continues!
New ESP32 Arduino version (v 1.03) remove this file “dl_lib.h” (and some others). Depending the sketch, probabily you can just remove this line because this library is beeing included but no method or function from this files is used.
In trouble with the WiFi.h you can try this hint:

Hi Adrian.
That means that your ESP32-CAM is not in flashing mode when you try to upload code.
Please make sure that GPIO 0 is connected to GND and that you press the RST button before clicking the upload button.
Try powering the ESP32-CAM with 5V as well as set the FTDI programmer to 5V.
Regards,
Sara
So after months of trying, I tried Flashing a new ESP32Cam and I have finally managed to flash a ESP32Cam.
The issue was that I needed to press and release the RST button after the

Then it flashed fine.
However I tried this on the 1st ESP32Cam which I had tried flashing time and time again before today and no luck.
I tried with the new method and still no luck!
Regards Adrian
Hello Sara/Adrian, thank you very much for your helpful troubleshooting guide. We had a lot of trouble finding a solution for the error “timed out waiting for packet header” on the ESP32-cam. We use now the 5V pin.
We first tried to follow your instructions:
“When you start to see these dots on the debugging window as shown below, press the ESP32-CAM on-board RST button.”
However we finally succeeded when we pressed de RST button UNTIL we saw the dots on the debugging window.
Great!
I’m glad you found a solution.

Sara
Hi,
I detected the same issue. Root cause is lacking of sufficient 3.3 V power via the USB – serial FTDIs. External 5 V supply to the ESP32 solved the problem.
In that case there is no need to connect 3.3, GND, TX and RX are sufficient (and IO 0 to GND).
DEAR SARA,
i have been encountering the following problem
“Board ESP32wrover (platform esp32, package esp32) is unknown”
“Error compiling for ESP32 Wrover Module”
in the Arduino IDE
PLEASE ANY HELP AS TO THE WAY FORWARD?
Hi.
I’ve found some poeple with similar issues. They were able to solve their problem as described here: https://github.com/espressif/arduino-esp32/issues/2388
I hope this helps.

Sara
Hi,
Thank you for a great tutorial.
Another approach to solve a problem.
My ESP32-Camera module is 2AHMR .
Upload of sketch working fine as described above.
But after reset, Camera was not recognized.
Tried with separate 5V power supply and different camera definitions in sketch – no luck.
Went back to AI-Thinker definition in sketch and uploaded the sketch with different Flash Mode. Instead of QIO, I used DIO.
That was the magic key for me. 🙂
I am keeping the external 5V power supply on 5V pin and using the USB2Seriel on 3.3V connected to 3.3V on the ESP.
I have experienced the Flash Mode issue before with other ESP32’s…
Regards.

Hello, how is this message? Can you help me, please?
[E][camera.c:1049] camera_probe(): Detected camera not supported.
[E][camera.c:1249] esp_camera_init(): Camera probe failed with error 0x20004
Hi Mary.
The 0x2004 error means the camera is not supported.
On your camera ribbon, which label do you have? Ours is LA AF2569 0927XA
What label do you have in your camera model?
Regards,
Sara
Mine is LA AF2569 0927XB. How to make it work?
Hi.
It’s the same as mine. It should work straight away with our examples.
Regards,
Sara
It say [e][camera.c:1049] camera_probe(): detected camera not supported. [e][camera.c:1249] esp_camera_init(): camera probe failed with error 0x20004
What code are you trying to run?
Are you sure you’ve selected the right camera board in the code or that you’ve inserted the right pinout?
Regards,
Sara
I used from camerawebserver in the arduino. I already selected the right camera board. When I used the coding from you, it said camera init failed with error 0x20004
Are you powering the ESP32-CAM with 5V?
Yes. I used 5V.
Make sure that the camera probe is well connected.
I don’t know what can be causing the issue :/
Our cameras always work out of the box.
Regards,
Sara
problem is that it doesnt supply camera with enough power – mA. Connect it to desktop pc or add another power supply to test it. IT WORKS..
I had the 0x20004 error exactly.
I had two camera definition lines uncommented in the example sketch. Once I commented out the wrong one, things worked.
Regarding “Failed to connect to ESP32: Timed out waiting for packet header”
Your schematic photo misled me:
https://i0.wp.com/randomnerdtutorials.com/wp-content/uploads/2019/03/ESP32-CAM-wiring-FTDI1.png?w=750&ssl=1
The FTDI has another pin layout as shown. Please consider to replace the image with something like this one:
https://buyhere22.com/components/usb-ttl-ft232rl-pinout.png
Also, I had the brownout issue using 3V. The 5V jumper settings in the FTDI needs also another counterpart pin on the ESP32! Something which wasn’t obvious for me.
Now, although I downloaded the latest arduino, the example code works great, I am unable to use the face recognition feature. Is there any further documentation on that?
Hi Markus.
What board are you using?
ESP32-CAM models without PSRAM don’t work with face recognition.
Regards,
Sara
Hello Sara, happy new year!
Finally got back to the project. Added a line to the setup-code: Yes, my board has PSRAM. I bought this board: “KeeYees WiFi + Bluetooth Modul Kit 4M PSRAM ESP32-CAM Dual-Core 32 Bit CPU” (smile.amazon.de/gp/product/B07S83X9NM/)
Alas, enrolling faces seems to have no effect at all. No fancy yellow rectangle, no text displayed. I tried different light environments.
Will debug the code…
Hi, Markus, happy new year! I have encountered the same problem as you. Now my online video stream works normally, but when I clicked the “Face recognition” and “Face Detection”, nothing happened and there is no colorful box displayed.
Besides, my board has also PSRAM. I still don’t know how to solve it? Do you have any progress on this problem?
I was constantly getting
A fatal error occurred: Timed out waiting for packet content
when uploading but the initial communication was working fine (esptool.py displayed the device details just fine).
The solution was to set the baud rate down to 115200. Maybe it’s the cheap CH341 USB-to-TTL module I’m using that cannot cope with higher baud rates.
Maybe this is helpful to others.
Thanks for sharing.

hello world, could someone help me? I managed to view 3 esp32-cam inside my house … but when I tried to access from the outside I can only view 1 esp32-cam … the question is: has anyone tried to add more than one camera by accessing it from the external?
Hi Rui/Sara,
Thanks for you excellent tutorials on the ESP32-CAM boards. I have it setup now with the cam-web-server-camera-home-assistant sketch, which works very well when used with Chrome/Firefox. I run into problems though when running it into VLC (just doesn’t connect) and into my VMS, which reports “Camera error – HTTP mulitpart stream header missing Content-Length’. Any ideas why VLC & the VMS are throwing an error?
Best regards
Andy
Hi Andy.
I don’t know why that happens – I never tried using VLC to check ESP32-CAM video.
Please note that the ESP32-CAM can only stream to one client at a time.
I’m sorry that I can’t help much.
Regards,
Sara
Could you help me pls I can’t find on any website pinout for fake camera. I checked all this stuf like voltage itd. but it didn’t help me. I will be vey grateful if you help me
Hi.
What is exactly the camera board you’re using and the error you’re getting?
Regards,
Sara
Leaving…
Hard resetting via RTS pin…
Hi.
That means the code was successfully uploaded.
Disconnect GPIO 0 from GND, open the Serial Monitor and press the ESP32-CAM on-board RESET button to get its IP address.
Then, you just need to open a browser and type the ESP32-CAM IP address.
Regards,
Sara
thanks for sharing amazing projects
i upload code to the board and everythings work fine but when i turn off wifi and then turn it on again, web server not work again and it need manual restart to work again.
how can i fix this?
Hi, I tried following the tutorial and managed to get everything working up to the point of obtaining the IP address from the serial monitor. I bought an ESP32-S from Bangood (the only difference to the one in the tutorial is that mine doesn’t have the words AI-Thinker imprinted underneath ESP32-S). https://www.banggood.com/ESP32-CAM-WiFi-bluetooth-Development-Board-ESP32-with-FT232RL-FTDI-USB-to-TTL-Serial-Converter-40-Pin-Jumper-p-1605463.html?rmmds=detail-left-hotproducts__5&cur_warehouse=UK

Rebooting…
Hi.
Take a look at bullet number 3.
Also, double-check that the ESP32-CAM is being powered with 5V. Check that with a multimeter.
Regards,
Sara
Hi,
I tried suggestions from bullet 3 but these don’t work. Checked the voltage input with a multiemeter and it was recieving 5V. I tried the ESP32 – WiFiScan Example and this worked fine however trying the ESP32-CAM Video Streaming and Face Recognition with Arduino IDE runs into the error mentioned in my above post. I don’t know if the WiFiScan uses PSRAM but if it doesn’t maybe this is the problem and my board is faulty?
Hi Andrew.
Did you select the right board on the code? So, that it uses the right pins for the camera?
Regards,
Sara
Hi Sara,
Yes I tried all of the above and rebuilt the circuit many times. I believe my board might be faulty as it is not detecting PSRAM, which it should be. I will let you know if the tutorials still fail to work upon receiving a new ESP32 board unless there is anything else you can think of that might help?
With best regards,
Andrew
Hello Sara,
Im using the AI Thinker module which includes psram and though face the Failed to get the frame on time-issue.
Perhaps someone knows a way to face this.
Having put together a soldered solution, your “How Too’s” are so good and then, I followed the Can’t get it to program, Point “1”!!!!
No Luck.
I then got another FTDI, and ESP-Cam module and, cobbled together, patched it. WORKED: Thanks sort of happy now.

Hey i thought i d share.Had the same problem, tried everything,wanted to toss it in the garbage.But than i looked at the camer ribbon cable and it looked assymetric up close.The plastic near the last right contact looked a bit wider than on the other side.Wich would mean it would be displaced in the slot. I sanded off just a fraction of milimeter, so it looked the same as on the other side. Put the camera in the slot, powered up the module and.. TADAAA, immediately i got IP with webcam working.
Great!
Thanks for sharing.

Hi.
The connections have already been revised, but the problem persists, I have even tried to put an external power supply, however nothing has resolved so far, I have also followed resolutions 2 and 3, and nothing too. Any more ideas? Thankful for the return.
had the same error, what fixed it was lowering flash frequency to 40Mhz and flash mode to DIO
I let my problem going until I had to get rif of it to go further : pictures are with artefacts above resolution SVGA.
Downgrade the frequency to 10MHz solved my problem : config.xclk_freq_hz = 10000000;
I get now very nice picture for all resolutions (I do not need framerate at all)
I was looking for that for a while… I do not beleive I’m the only one !!!
Hope it will help many makers.
Maybe I got too cheap cameras ^^ !

Hello,
I fell into all the traps without getting out of it, suddenly I changed my rifle
and I started on the Time Lapse proposed by the bitluni laboratory: https://bitluni.net/esp32camtimelapse
On the one hand, it works well, and seems more stable ;
and on the other hand, I was able to add the use of the GPIO0 port to use the ESP32 as a sound detector (via the FFT) and trigger a reboot that takes the photo.
I think your instructions should mention dropping the upload speed to 115200.
Until I did that, I couldn’t upload the sketch. I had to read the instructions on ‘instructables circuits’ to find that out. Others had the same issue, judging by the comments here.
The suggested upload speed is 115200. However, the speed of 962100 is also workable. A reliable upload speed varies from project to project. Even, the placement of the TX and RX wires can affect the upload speed.
Hi ,
I used esp32-cam in some dark scene， so added LEDC module for LIGHTING. I tried GPIO 4 ,14, 15, LEDs worked well. But the camera could not started up(camera can’t work with LEDC together?).
error messages:
E][sccb.c:154] SCCB_Write(): SCCB_Write Failed addr:0x30, reg:0xff, data:0x0
Hi.
It can.
But you probably need to use a different PWM channel.
The OV2640 camera uses PWM channel 0 when working with the ESP32-CAM. So, if you’re using PWM with the ESP32 and the camera at the same time, select a different channel for the PWM that is controlling the LED.
I hope this helps.
Regards,
Sara
yes, it does work!
Thx

Hello I am getting this error while compiling. Can someone kindly help me resolve the issue.
camera_pins.h: No such file or directory
Hi.
Which project are you following?
That means that you don’t have the camera_pins.h file on the sketch folder.
If you’re following this tutorial: https://randomnerdtutorials.com/esp32-cam-video-streaming-face-recognition-arduino-ide/
Make sure you have a tab in your Arduino IDE, called camera_pins.h
If you’re following that particular project, in your Arduino IDE, go to File > Examples > ESP32 > Camera and open the CameraWebServer example.
It should have several tabs, and one of them is called camera_pins.h

hi, i am having a problem uploading the code… i had already checked the wiring and they are all good. Besides, i had changed the 3v to 5v and it still doesn’t work… i pressed the reset button too while uploading. what should i do?
Hi, if the serial monitor print out “waiting for download”, does it means my network connection is too weak?
Hi.
That means you forgot to disconnect GPIO 0 from GND. That means the ESP32 is in flashing mode.
Disconnect GPIO 0 from GND and you won’t have that issue. The ESP32 will run the code.

Sara
Hi Sara,
perfect hint! Thank’s a lot.

Hello, congratulations on the excellent work you are doing. Let’s see if you can orient me, my ESP CAM, goes well but in browser you only see image, does not load configuration menu. What am I doing wrong? What’s the matter?.
Best regards.
Hello, problem solved, I have been playing with different sketches and I had one modified by Rui loaded that did not have the configuration menu
Regards.
As a newbie, working with ESP32_CAM, I found I have almost all the issues mentioned above and in the guide. I never take a compilation failure as true unless I have: 1) powered off the project; 2) reset the wires on the breadboad; 3) checked the camera; 4) checked the wires on my TTL comms board. Then if I get the error three times in a row I assume something has changed in my code, maybe an accidental key press or even an intentional change that is incorrect.
Then I check google and github for the details of the error, then I might ask for help. Sometimes it is just a lack of information in a fast changing world; sometimes it is my pure ignorance because I am not a programmer and I do not know the compiler language. I hope I am learning along the way!!
I can’t connect ESP32-CAM to my routers Fritzbox 7390, TL-WR841-dd-wrt or GalaxyS10 Hotspot.

I don’t get an IP-Adress
My Fritzbox-router shows under “unsuccessful login attempts” the correct MAC-Adress from ESP32-CAM-Module
I Resetted the board multiple times
What can i do?
I have solved the problem with the Wifi-connection!
You have to use the code from this web-site here, but not the code in Arduino/File/Examples/ESP32/Camera/CameraWebServer!
So i could connect to my Wifi. After this i tried again Arduino/File/Examples/ESP32/Camera/CameraWebServer and i could also connect!
Now everything works fine. Don’t ask me why…
Hi Horst. Which website are you referring to when you say “You have to use the code from this web-site here”? Where is here? Thanks
I refer to: ESP32-CAM Video Streaming Web Server
https://randomnerdtutorials.com/esp32-cam-video-streaming-web-server-camera-home-assistant/
I cannot get an IP address in the serial monitor.
I have :
1) Checked my TX and RX connections to and from the FTDI to the ESP32-Cam
2) Checked the baud rate as 115200 in the serial Monitor
3) Moved my router within 2 feet of the ESP32-Cam
4) Checked and rechecked my SSID and Password
My router shows that 2.4 and 5 GIG are activated
Can you help me solve this problem ?
Hi.
After uploading the code disconnect GPIO 0 from GND and with the Serial Monitor opened, press the RST button.
Regards,
Sara
I’ve done all that is suggested on section 8 of the Tutorial. Cannot connect.
Tom:
If you tried a simple sketch and still cannot connect then you may have a bad board. If you would like me to look into it, please let me know what you have. Where you got it.
Regards,
I use the following sketch to test any ESP board that I got to make sure I am able to talk with the ESP serially: download and upload before I work with any sketch. This makes sure that the basic communication is working. Hope this helps!
int i;
void setup() {
// put your setup code here, to run once:
Serial.begin(115200);Serial.println();
Serial.printnl(“Power UP!”);
}
void loop() {
// put your main code here, to run repeatedly:
serial.print(“Loop: “); Serial.println(i);
delay(1000); i++;
}
My esp32 cam is working both for streaming and snapshots. However, the picture quality is nowhere near as good as I see on this and other tutorials. Some details:
I am using the camerawebserver example included with the library
I’ve tried quality settings in the code from 0 down to 20. Doesnt really help. Camera crashes at a quality setting of about 4.
The camera model is an OV2640-v2.0. AI-thinker
Powered at 5V
Wifi signal is fine. The board is 3 feet away from the wireless router.
I have searched extensively online and I’ve seen only one discussion on this point. The recommendation there (although without resolution) was to take a look at the compression settings in the code, which I don’t see how to change.
Any ideas would be appreciated.
My esp32cam is working just fine using the board setting – AI thinker ESP32-cam. But the video is poor and low fps. Then I found some tips on improving the fps on the internet by using the board setting – ESP32 Wrover Module and and partition scheme : HUGE App(3MB No OTA/1MB SPIFFS), right after I uploaded the sketch I got errors saying
[E][camera.c:1049] camera_probe(): Detected camera not supported.
[E][camera.c:1249] esp_camera_init(): Camera probe failed with error 0x20004
Any solutions? Thanks!
Hello,
For those having the : “esp_camera_fb_get(): Failed to get the frame on time!” error.
Just got it on 2 new cheap Esp32 CAM clone.
I resoldered/reflowed the ESP32-S and CAM connector connections using flux + bit of solder on iron tip and work like a charm now
Please note, there are two different camera types available when you order the esp32cam module either the “landscape” the “portrait” camera is available on the market. The one with: 8225N V2.0 171026 gives the image in the same direction as the text the chip “ESP32-CAM” the one with: TY-OV2 6400V2.0″ gives the image rotated 90 degrees.
Mine has DCX-OV2 640-V2 on the ribbon, don’t know which way round it is yet as I haven’t managed to get an image out yet.
I have problem #4. When I look at the tools menu, there is no Partition Scheme option. Am I correct that the boards.txt file has to be updated to contain ESP32? What are the options for ESP32? Where do I find the boards.txt file on Windows 10? I have found one in Program Files (x86) > Arduino > hardware > arduino > avr. Is this the right one?
Thank you, I appreciate your help.
Hi.
You need to select ESP32 Wrover Module in the Boards menu to have the partition scheme option.
Regards,
Sara
Hi! I can’t find the ‘Partition scheme’ option in my arduino IDE whenever i select AI THINKER Esp32cam.
Hi.
The partition scheme only shows up if you select “ESP32 Wrover Module”.

Hi,
I´m using the FTD1232 with the ESP32 module, can upload the code without issues. I remove GND and do a reset but do not get any output in the serial monitor (set to 115200 Baud). Rx Tx cabling is correct. Do I have a bad board or are there any tricks/settings to get the serial monitor working?
Thanks in advance.
Hi.
There are no tricks.
After resetting the board, you should get something on the serial monitor.
Regards,
Sara
Tom:
Sarah is right – there are no “tricks”. However, there are steps to troubleshoot problems. Below is step 1.
Before you run the camera sketch, please try the following to make sure the ESP32 can “talk” to your PC.
void setup() {
// put your setup code here, to run once:
Serial.begin(115200);
Serial.println();
Serial.println(“Power Up!”);
}
void loop() {
// put your main code here, to run repeatedly:
Serial.print(“*”);
delay(1000);
}
我的错误是：

Hi Martin (and Sara)
It is only almost18 months since you wrote this comment, but I too have found this (ESP and transistor, AND PIR getting hot in my case)
I found that increasing the delay to 10 seconds killed that issue. Clearly a lesser time should also be fine but the coded delay as supplied was too short.
Neither my camera nor ESP nor PIR are faulty (currently)
Hi
Please help me on the below issue. As soon as I upload the sketch and restart by pressing the reset button, after removing the GPIO and ground short (for upload purposes), it throws the below error continuously and doesn’t go beyond this forever.

Hi,
I’m having trouble while the ESP32-CAM is connected only to the power supply. It doesn’t connect to the Wifi network and I’m not able to open the web server of it and it doesn’t show in the IP scanner. With FTDI (serial monitor) and power from it, it works fine.
The power supply is powerful enough and it shows current draw around 170 mA.
Any ideas what can be wrong?
Hi.
After powering the board, press the RST button.
Regards,
Sara
psramFound() is returning false, but I can see the pSRAM chip on my board.
I have tried two board, both chips are labeled ESP32-S and are suppose to be AI Thinker modules. Almost everything else seems to work, I just can’t get the pSRAM to work.
On the brownout issue. For programming the 3V setting on the ftdi with 3V power connections to ESP worked best. Running the ESP32CAM on 3V gave the brownout error. Running on 5v connection(jumper move on FTDI) eliminates the brownout error.
My take, programming requires no WiFi power. Wifi power consumption on my board may not be to spec. (very in-expensive board)
i had terrible brownout issues. struggled for days – tried everything on the forums.
Solution – just connect the desktop power to the esp32-cam and all my troubles disapeared.
seems the esp32-cam runs so close to the 5v power limit, that 5v from a desktop power supply is required when connected to the computer’s usb port. not quite enough power and that makes all the difference.
Project all works fine – much better with a good external antenna and separate PSU.
However, the video stream to the web page on the stated IP address stops after about 5 minutes and I have to reload the web page and restart the camera stream. Any ideas what might be causing this?
This is my first ESP32, I choose this ESP32-CAM-MB because it seems to be easy to start.
But, I am getting the message
“Leaving…
Hard resetting via RTS pin…”
At the end of upload.
There is a RST button on the esp32-cam, and the same RST button on the esp32-cam-mb. There is a second button on the esp32-cam-mb named IO0.

Hi.
The “Hard resetting via RST pin” is a normal message that you get after a code is uploaded successfully.
After that message, you just need to press the on-board RST button so that the board starts running the program.
Regards,
Sara
Hi Sara,
Yes, you are right. The upload was ok. I just realize that I can monitor the serial comunication to see the controler messages.
Thanks a lot.

Hi everyone !
I can upload the code, I solved all the problems with the troubleshotting done by Randomnerdtutorials. The website is great!
But esp32-cam keeps crashing. I turn it off and on again and it works again. I have seen some saying that I would decide to put an electrolytic capacitor in the DC 5v supply. I put it on and it continued to generate the same problem. I really don’t know what else to do.
If someone there managed to solve the problem, please tell me what was done!
Thank you all !
Hi, it seems to be a dirty the electric contact with the 5v and GND pin’s. Try to inforce it or sorder it.
Hi!
I cleaned the contacts. I re-soldered the wires. It didn’t. I will buy 2 more cards and see if this same defect happens to them. Thanks for the answer.
Hello,
I have a SP32cam AI Thinker and I have programmed with the software ESP32-CAM_MJPEG2SD from github.
It should provide a setup with a static IP/address. It did not.
I´ve tried several changes until I decided to choose the setup from this https://randomnerdtutorials.com/esp32-cam-static-fixed-ip-address-arduino/ site and it works well.
That aside, the camera allways powered up and loaded the code, until now.
I fail to see where the code for a static IP/address can influence the boot process.
I got even back to the original code to control that possiblity but with the same result, no boot.
It is vital that by applying power, the camera starts.
Why is it that until now the camera allways has start and all of a sudden no more.
Pressing the reset switch on the cameraboard let it boot, but that is not a practical solution for obvious reasons. One of the pins should activate a reset but pin -1 (minus 1). But I see no pin -1.
So, connecting a switch between pin -1 and 0V is troublesome for there is no hardwired one.
What can I do?
I can confirm getting “Brownout detector was triggered” when using FT232RL in 3.3V to the 3.3V pin on the ESP32-CAM. Setting jumper to 5V and connecting VCC to 5V pin fixed it.
Used 3.3V for programming because i was warned not to put 5V on RX, so in my case programming worked ok on 3.3V power+rx.
hi Sara,
i’m beginner in Arduino, but i try to made one thermometer (DS18B20 ) using ESP32-CAM and display on the OLED (0.96″ I2C IIC Serial 128*64). I don’t find one example for this. where i connect SDA and SLA? on the serial monitor work.
Hi.
You can connect the SDA and SCL to any available pins that are not being used yet by other peripherals.
Then, you must specify the pins you are using in the code. It may be useful to take a look at this tutorial about I2C: https://randomnerdtutorials.com/esp32-i2c-communication-arduino-ide/
Regards,
Sara
thk . will try.
Hi
I ve an issue that is not reflected in the guide. I am using the ai-thinker cam with arduino nano as programmer. If I do everything as the guide says, the serial monitor takes forever to give an IP. It’s all dots. But i know that the wifi funcitions are working, since the soft AP mode works perfectly.
How can I solve it? and is there any way to connect openCV in python to a softAP?
Hi.
Usually, when you receive a lot of dots on the debugging window it is one of the following issues:
– wrong SSID/password;
– weak wi-fi signal: the ESP32 can’t get wi-fi signal from your network;
Regards,
Sara
Hello,
For wifi communications, or lack thereof, check the 0 ohm resister on the back side of the board by the brass/copper connector. If you’re using the built in wifi antenna, the resistor has to be “this way” and if you’re using the external antenna, it has to be “that way”. See this link, https://randomnerdtutorials.com/esp32-cam-connect-external-antenna/
That is if the coding, SSID/password are all correct.
Eric
Dang good idea.. I have however got my little toy working well now.. But your idea is a good one and I will remember that.. thanks brother for your advice.. I am just learning electronics and at almost 70 it is a lot harder then when I was 20.. But we were still riding carts and banging rocks together..😏
Hey guys
No matter what I do I keep getting: “time out waiting for packet header” While I am trying to get my 32 cam working.. I have tried arduinos one FTDI board. three different esp32 cams changed wires 3.3 & 5 vdc tries.. It is all wired good but no dice. I see where you say you have tried to recreate some of these faults but couldn’t.. I am willing to pack up this whole mess arduino, wires esp32 cam and send it off to you.. all wired like I have it now for you to play with if your interested.. I have my arduino IDE update with the correct library and sketch. If you write to my email address I can copy and paste the sketch but it is the downloaded one with the change in the camera and my wifi name and password changed.. I just do not know what to do about this silly thing.. Now you must understand that I turn 70 this year so it maybe that I just do not “see” something simple.. but as many times as I have been over this. Plus the many days I have left it set to go back with a clear mind.. I just can’t get it right.. Love you site by the way.. let me know if you want this thing and where to send it.. thanks for all your help on this site..
Hi George.
You are probably doing something wrong with the wiring or selecting the board… It is very unlikely that all boards are faulty.
We already have plenty of ESP32-CAM boards. I’m sure any other people will benefit more from your offer. But, thanks anyway.
Regards,
Sara
Yeah that is what I thought at first.. But I have been over it about 15 different times from 4 or 5 different sites.. and the set up is always the same the only difference is weather I use 5 or 3.3 vdc..So I do not think that is the problem.. I mean all you have is text and receive ground and voltage then ground out gpio 0 pin and that is it.. Not to difficult.. Thanks a lot for trying to help Sara.. it could be anything so let me know if something else pops to mind.
I also push the reset button on the esp32 cam before the program downloads My next move I think might be to use my 357 wrench on it.. thanks again for your help..
G,
Not sure where you’re seeing the “packet header” message. Did you try the ESP32-Cam example? What I found out is that I can only “access” the streaming video from one device. I had a web browser on my laptop connected to the ESP32-Cam on port 80 and tried to connect my iPhone to port 81. It did not work until I closed the browser on the laptop. I am new to this stuff also so I am sure it is something simple. The board I selected is AI Thinker ESP32-CAM and the line in the code is #define CAMERA_MODEL_AI_THINKER
Eric. I figured it out.. or should I say it started to work for mt. I think it might have been some defective wires I was using.. But got it loaded then it went into brownout but once I changed from 3.3 to 5 vdc it all worked fine… But these little sucker seem to run hot.. I wanted to set up a small backyard wildlife camera set up.. But I think these will over heat after a while and I need to figure out how to turn the power on and off remotely. and ideas my brother? thanks for you help..
Good morning! I’m new to this also so I may be wrong, I believe that the WiFi chip does run very warm if it’s running 24×7. Some ideas off the top of my head is to put it into deep sleep at night because the cam isn’t infrared. Use a PIR sensor to turn on WiFi when it detects motion. Or a RCWL 0516 microwave Doppler radar module. I don’t know how sensitive those are with small animals so it may not work. If it’s a bird feeder or something, a HC-SRO4 ultrasonic module might work. As far as turning power on and off, I’m not sure but I think LORA (Long Range) and light/deep sleep feature would do the trick as far as power consumption. LORA can be used to wake it up. If you want to turn WiFi on remotely, try the LORA ESP32’s. Videos and Pictures do not go over LORA very well so you’ll need WiFi. You could have LORA send you or Node-Red a message and you/Node-Red can send WiFi activation command or something. Might miss out on some of the image capture while WiFi is staring up though.
Hi,
I made the project: ESP32-CAM PIR Motion Detector with Photo Capture (saves to microSD card). Working well, but sometimes freezing with the following errors:
[E][camera.c:1113] camera_probe(): Detected camera not supported.
[E][camera.c:1379] esp_camera_init(): Camera probe failed with error 0x20004
Only reset can help and works well till the next same error.
Can somebody help me?
Many Thanks!
Hi guys,
Firstly, I would like to thank you for your tutorials and help.
My esp32cam is working just fine using your example – it is an AI thinker module ESP32-cam.
That meaning i get a stream on my firefox web browser. During this time the serial port in my arduino IDE reports the mjpg stream and everything looks good.
However after 3-8 minutes streaming stops for no apparent reason, both in the IDE serial port and web browser (with a broken frame). At the beginning I thought that this could be a wifi issue but it isn’t as the esp is still connected (just in case i added some code for wifi re connection in the loop). Also I have added mqtt functionality.
Is there an explanation for this behavior or any suggestions as to what to look for? Thanks!
I think that this erratic behavior was due to overheating. I rewired the setup, took it out of the breadboard and now it works for 2-3 hours without interruption. Now I will have to find a way to cool it down, especially if I put it in an enclosure.
