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 2.0.3.0
Server: NA
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?
Can you repeat updating the FW using STM32Cube but do not use the .bin file. Use the .hex file. Its the .hex that contains the bootloader and application code.
If you will use the RAK DFU Tool, then .bin file is the one needed since that’s the one with the RAK811 Application FW.
On the .hex, it includes both the bootloader and application FW. Before, v3.x.x.14, the FW for the bootloader is separate, now they are in one .hex file
