Dear @Luynmax , This is a typical error of RAK3172. Reason: In the program we did not leave any break time to check the requirement to flash code. Therefore, the circuit board will run continuously without paying attention to the signals sent from the IDE. So I recommend that you leave a little delay in your loop() or at least a 1 second delay in setup.
In this case, you can send a signal to the circuit board to request immediate BOOT MODE.
Syntax: AT+BOOT
When receiving this signal, the circuit board will go into BOOT MODE and wait for you to flash. If the circuit board ignores this request (does not return BOOT MODE), try resetting the circuit board by pressing the reset button on the circuit board. Then spam AT+BOOT
If the AT+BOOT
Thank namamiot, I tried and loaded the code successfully
