I have a RAK11310+RAK5005-O base board. So far I manage to run some codes and it works well. But when I try to access to RAK_SERIAL_PORT_TOOL_V1.2.1 that provided by RAK, the program tends to freeze when I send a simple AT command to the device.
Refer to fig below. When I click “SEND” to send at+version, the program does not respond and freeze until I unplug the USB that connect to the RAK11310 board.
My question is: how do I access to RAK11310 AT command mode so that I can alter the hardware parameter (e.g. DevEUI etc)?
