Me again! using the rak3172 I get random AT_COMMAND_NOT_FOUND responses from different RAK modules, sometimes everything runs fine and every now and then I get that response(with different AT commands) my example below is with join AT
This is my routine for joining the lora Network
if I reset the RAK3172 then it runs fine.
I thought that maybe the AT command was not send properly so I was able to put another UART reader in between the RAK3172 and my uC and this is what I saw
So it looks like the message is leaving my uC with all the characters.
This is my FW version
Any clues of what the issue could be?
