FAQ

Q: Why does the ESP32-S3 not output logs on UART0?

A: By default, the ESP32-S3 outputs logs via USB instead of UART0. To switch the log output to UART0, modify the configuration in menuconfig:

Path: Component config → ESP System Settings → Channel for console output

After setting the output channel to UART0, rebuild and flash the firmware for the change to take effect.

Q: Why can't LoRaWAN join the network (Join fails)?

A: Please check the following steps one by one:

1. Verify that DevEUI, JoinEUI (AppEUI), and AppKey are correct;
2. Ensure the device is properly registered with the network server;
3. If the parameters are correct but joining still fails, try modifying the JoinEUI and initiate Join again;
4. Check whether the frequency band (Region) configured matches the gateway;
5. Confirm that the antenna is properly connected and the signal environment is good.
