Issue: Error Codes
Setup: Serial Terminal > Ubuntu 20.4 > USB to UART > RAK4200 Breakout
and NODEMCU ESP8266 > RAK4200 Breakout
Can send data using ABP to The Things Network.
Can not join with OTTA.
I receive error codes even with a successful send of data (ERROR: 96) and others ERROR: 99 and ERROR 2 (Syntax Error from what I can figure out.)
Can someone please point me in the direction of an error code list for the RAK4200 thanks.
