Issue:Just setting up RAK811 breakout board(s). Using either RAK Serial port tool or minicom (debian) nearly all at commands return ERROR-1 or ERROR-2
Setup: Windows 10 PC + RAK Serial Port tool, generic FTDI USB. Same problem on Raspberry pi with a direct UART connection to RAK811 breakout and minicom terminal. RAK 811 Firmware is 184.108.40.206
Details: Apart from at+version and at+boot which return the expected responses, all other commands I receive ERROR-1 or ERROR-2. This includes basics such as at+get_config=device:status.Any suggestions on what I can try?
