Otherwise, it will fail the pin assignment and the camera will fail to init. In this example, we’re using the CAMERA_MODEL_AI_THINKER, so it’s the one that is enabled. You just need to uncomment the right camera module and comment all the others: //#define CAMERA_MODEL_WROVER_KIT Make sure you select the right camera module in your projects. 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.

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. Sometimes, unplugging and plugging the FTDI programmer multiple times or restart the board multiple times, might solve the issue. 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. Measure the output voltage of your FTDI programmer (VCC and GND) using a Multimeter to ensure it’s providing 5V to your ESP32-CAM.

Some of our readers reported that they could only upload code when the ESP32 was powered with 5V. 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“. Also, check that you have the FTDI programmer jumper cap set to 5V. You should also press the on-board Reset button to restart your ESP32 in flashing mode.

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. Failed to connect to ESP32: Timed out waiting for packet headerĤ) When you start to see these dots on the debugging window as shown below, press the ESP32-CAM on-board RST button.Īfter a few seconds, the code should be successfully uploaded to your board. esp_camera_fb_get(): Failed to get the frame on time!ġ.

If you have a different problem or a different solution to these issues, you can share your tips by writing a comment below. However, we’ve gathered all the information given by our readers to get answers to the most common issues. Please note that we couldn’t reproduce some of the errors on our end. We’ve modified some lines on the code, so most of the problems related with that project should be fixed. Note: some of our readers reported errors when trying to follow the ESP32-CAM project with Home Assistant.
