I am trying to configure an HC-05 Bluetooth Module. To do this I have to set the device to AT command mode and then use the Serial Monitor to input commands after uploading a blank sketch. When I try to input commands, the Serial Monitor and the rest of the IDE freezes after the 3rd command. I even disconnected the HC-05 module, and even when connected only to the XIAO board itself the Serial Monitor freezes after a few commands.
Is there any advice on what’s causing this?
