Troubleshooting

Important: Be sure you're using a good quality USB cable and you have enough power source for your project.

  • Programming Fail: If the programming/flash procedure fails, try to reduce the serial connection speed.
  • COM port not detected: Check the USB cable connection and the USB to Serial driver installation.

If the error persists, you can ask for help at the official ESP32 forum or see Contribute.
