6. Troubleshooting
- Board not recognized by computer: Ensure USB-C cable is functional and drivers are correctly installed. Try a different USB port or cable.
- Wi-Fi/Bluetooth connectivity issues: Verify the external IPEX antenna is securely connected. Check your code for correct Wi-Fi/Bluetooth configuration. Ensure the antenna is not obstructed.
- RGB LED pin discrepancy: Some documentation might incorrectly state the RGB LED is on GPIO38. The correct pin for the RGB LED is GPIO48. Adjust your code accordingly if experiencing issues with the onboard RGB LED.
- Firmware upload failure: Ensure the board is in bootloader mode (usually by holding the BOOT button while pressing and releasing RESET, then releasing BOOT). Check serial port selection in your IDE.
