Issue: After programming the deveui and appkey - an Error 82 (The Lora Parameters are invalid) is generated when trying to join Lora network
Setup: Any firmware revision : V3.3.0.15 , V3.3.0.16 and V3.3.0.18
Details: A new RAK4720 will join the LoRa network without any problem in the default OTAA mode
After programming the RAK4270 the Error 82 Occurs. Reflashing the RAK4270 with the same firmware version or a different firmware version does not overcome the error.
Using the command at+set_config=lora:default_parameters also does not overcome the error 82.
