one. Failed to connect to ESP32: Timed out waiting for package header

ESP32-CAM Failed to connect to ESP32: Timed out waiting for packet header

This error means that the ESP32-CAM is not in flashing way or it is not connected properly to the FTDI developer.

Double-check the steps to upload code

Double-bank check that you've followed the exact steps to put your ESP32-CAM in flashing mode. Declining to complete one of the steps may result in that mistake. Here'south the steps you demand to follow:

Connect the ESP32-CAM lath to your computer using an FTDI programmer. Follow the next schematic diagram:

Of import: GPIO 0 needs to exist connected to GND so that yous're able to upload code.

Many FTDI programmers accept a jumper that allows you to select 3.3V or 5V. Brand sure the jumper is in the right place to select 5V.

Important:GPIO 0 needs to be connected to GND and then 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) Become toTools>Lathand selectAI-Thinker ESP32-CAM.

two) Go toTools>Portand select the COM port the ESP32 is connected to.

3) Then, click the upload push button to upload the code.

4) When yous start to see these dots on the debugging window as shown below, printing the ESP32-CAM on-board RST button.

After a few seconds, the code should be successfully uploaded to your lath.

GPIO 0 must exist continued to GND

Important: if you can't upload the lawmaking, double-bank check that GPIO 0 is connected to GND and that you selected the correct settings in the Tools carte du jour. You should too press the on-board Reset button to restart your ESP32 in flashing mode. Also, bank check that yous have the FTDI programmer jumper cap set to 5V.

Check the FTDI programmer you lot are using

I of our readers reported the following: "found out that you tin program the board with a USB-to-TTL module model CP2102 and that the CH340 model does Non work". This is the FTDI programmer we're using.

Power the ESP32-CAM with 5V

Some of our readers reported that they could but upload lawmaking when the ESP32 was powered with 5V. Then, power the ESP32-CAM with 5V.

FTDI Developer 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

ESP32-CAM Camera init failed with error 0x20001 or similar

If yous become this verbal error, it means that your camera OVX is not connected properly to your ESP32 board or you have the incorrect pin assignment in the lawmaking.

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 correct abroad and with a secure fit, otherwise it volition fail to found a connection.

Wrong pin consignment in the code

When you get this error, information technology might also mean that you didn't select the right board in the ascertain section or the pin definition is incorrect for your board.

Make certain you select the right camera module in your projects. Y'all only need to uncomment the right camera module and comment all the others:

          //#ascertain CAMERA_MODEL_WROVER_KIT //#define CAMERA_MODEL_M5STACK_PSRAM #ascertain CAMERA_MODEL_AI_THINKER

In this example, we're using the CAMERA_MODEL_AI_THINKER, so it's the 1 that is enabled. Otherwise, information technology will fail the pivot assignment and the photographic camera will fail to init.

In that location are many esp32-cam boards being released ("fake boards") that the wiring between the ESP32 and the OV camera might be different, and so selecting the camera module, might not be enough. You might need to check each gpio annunciation with your board pinout.

For example, M5Stack board without PSRAM has a dissimilar pin assignment than the M5STACK with PSRAM (defined on the code by default). Then, you need to change the pivot definition in the code accordingly to the board pinout.

Not enough power through USB source

If yous're powering your ESP32 through a USB port on your computer, it might non be supplying plenty 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 besides mean that your camera or the camera ribbon is broken. If that is the case, you may get a new OV2640 camera probe.

iii. Brownout detector or Guru meditation error

When you open your Arduino IDE Serial monitor and the fault message "Brownout detector was triggered" is constantly being printed over and over once again. It ways that there'due south some sort of hardware problem.

Information technology'due south often related to one of the following issues:

Poor quality USB cablevision;
USB cable is likewise long;
Board with some defect (bad solder joints);
Bad computer USB port;
Or not enough power provided past the computer USB port.

Solution:

endeavor a different shorter USB cable (with data wires)
use a different computer USB port or apply a USB hub with an external power supply
some readers reported that when powering the ESP32-CAM with 5V, the outcome was stock-still.

Also, follow the suggestions described in issue 2.

4. Sketch too large error – Wrong division scheme selected

ESP32-CAM Sketch too big error Wrong partition scheme selected

When you become the following error:

          Sketch too big; meet http://www.arduino.cc/en/Guide/Troubleshooting#size for tips on reducing it. Error compiling for board ESP32 Dev Module.

Information technology ways that you lot haven't selected the right partition scheme. Brand certain you select the right partition scheme. In your Arduino IDE, go to Tools > Division Scheme, select "Huge APP (3MB No OTA)".

five. Lath at COMX is not bachelor – COM Port Not Selected

If you become the following error or similar:

          serial.serialutil.SerialException: could not open up port 'COM8': WindowsError(2, 'The arrangement 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 non bachelor

Information technology means that yous haven't selected the COM port in the Tools carte. 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 information technology is non properly connected to the USB connector.

6. Psram error: GPIO isr service is not installed

ESP32-CAM Psram error GPIO isr service is not installed

You are using a board without PSRAM and yous get the following fault or similar:

          Eastward (161) gpio: gpio_isr_handler_remove(380): GPIO isr service is not installed, call gpio_install_isr_service() first Photographic camera init failed with error 0x101

when 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 prototype resolution so it won't need and then much space to store images. However, as a result, you cannot become some high resolution formats due to the limited retention):

          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 = i; }

Note: face up recognition and detection doesn't piece of work with boards without PSRAM. Nevertheless, you tin withal use all the other functionalities of the board. For example, although yous can't apply the face up recognition and detection features of this project (ESP32-CAM Video Streaming and Face up Recognition with Arduino IDE), you can however play with the example and explore the board features as long as you have the right pin assignment in the code.

vii. Weak Wi-Fi Indicate

Some readers reported that subsequently powering the ESP32-CAM with 5V, they've gotten a more than stable Wi-Fi signal. You tin read this dedicated guide to larn how to connect an external antenna to the ESP32-CAM and extend Wi-Fi coverage.

The ESP32-CAM has the choice to use either the built-in antenna or an external antenna. If your ESP32-CAM AI-Thinker has no Wi-Fi connection or poor connexion, it might have the external antenna enabled. If yous connect an external antenna to the connector, it should work fine.

Check if the jumper 0K resistor past the antenna connector is in the proper position for the desired antenna. In that location are three picayune white squares laid out like a "<" with the center position being common.

The following photo shows a closer expect at that area. You can clearly run across a minor 0K resistor connecting to the born antenna.

esp32-cam connected to built-in antenna — Photo courtesy of Helmut Schoenborn

With lath turned so the the PCB antenna is upwardly:

To use the PCB antenna, the resistor must be on the elevation position, like this: /
For the antenna connector, the resistor must be on the lesser position, like this: \

So, to enable the on-lath antenna:

Unsolder the resistor that goes to the antenna, it's in this position \
And solder together the 2 connections to enable the on-board antenna.

8. No IP Address in Arduino IDE Serial Monitor

f you just encounter dots printed in the serial monitor (……), it means that your ESP32-CAM is not establishing a Wi-Fi connectedness with your router.

Double-check your network credentials

You lot 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* countersign = "REPLACE_WITH_YOUR_PASSWORD";

Select the correct baud rate in the Arduino IDE Series Monitor

If you don't select the correct baud charge per unit in the Arduino IDE Serial Monitor, you won't get your board IP address or y'all'll just get garbage on the screen.

Brand sure you select the correct baud rate. In our examples with the ESP32-CAM, we utilise 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-cheque 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 non able to found a serial communication with your estimator.

Wi-Fi Range

If the router is far away from your ESP32 board, it might not be able to grab the Wi-Fi point. Ensure that your ESP32-CAM is fairly shut to your router.

ix. Can't open up spider web server

If the ESP32-CAM is printing the IP accost in your Arduino IDE Serial Monitor, merely when you try to open the web server in your spider web browser you meet a blank screen, information technology 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 just work with one client connected at a time.

ten. The image lags/shows lots of latency

Having some latency is normal for such a small and cheap photographic camera. Some readers take suggested the post-obit to reduce latency:

Power the ESP32-CAM with a standalone 5V power supply
Reduce the frame size with the post-obit in your code:
config.frame_size = FRAMESIZE_SVGA or config.frame_size = FRAMESIZE_VGA
Use an external antenna.

eleven. esp_camera_fb_get(): Failed to get the frame on time!

We've personally never faced this upshot. 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 Blazon-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/primary/README.md and ringlet downward to Interface Comparison.

The CameraWebServer Arduino example we're probably all using doesn't have this ESP32-CAM model divers.

You need to add it yourself in the main tab add:

          #define CAMERA_MODEL_M5STACK_NO_PSRAM

And in the camera_pins.h tab add together the post-obit:

          #elif divers(CAMERA_MODEL_M5STACK_NO_PSRAM) #define PWDN_GPIO_NUM -1 #define RESET_GPIO_NUM xv #define XCLK_GPIO_NUM 27 #ascertain SIOD_GPIO_NUM 25 #ascertain SIOC_GPIO_NUM 23 #define Y9_GPIO_NUM nineteen #define Y8_GPIO_NUM 36 #define Y7_GPIO_NUM 18 #define Y6_GPIO_NUM 39 #define Y5_GPIO_NUM 5 #ascertain 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 21

And yous're good to go.

Also note that the max resolution of the bare ESP32-CAM Module is XGA 1024×768, I presume too considering of the lack of PSRAM. "

We hope this suggestion solves your issue. Let usa know in the comments section.

Using larger microSD card sizes

Co-ordinate to he datasheet, the ESP32-CAM should only supports 4GB microSD cards.

However, we've tested with 16GB microSD carte du jour and it works well.

You might not be able to shop more than 4GB, fifty-fifty though y'all accept 16GB. We haven't tested storing more than 4GB, so we're not certain well-nigh this.

Are these projects uniform with M5Stack board?

Yeah, the M5Stack ESP32 board is uniform with out projects. Still, you lot must bank check your camera pinout to ensure you have the right assignment in the code.

Y'all tin can bank check the M5Stack camera connections here.

How to set a fixed the IP Address

To fix a static/stock-still IP address, you tin follow the next tutorial:

ESP32 Static/Fixed IP Address

Setting ESP32-CAM as Admission Point (AP)

You tin 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 tin apply the following code to set your video streaming spider web server every bit an Access Point:
