Issue: When the RAK4270 receives an ADR command from the server sometimes reports ERROR 20
Setup: EU868
Server:
Details:
A payload is sent from the RAK4270 every 15 minutes.
After 20 payloads the RAK4270 receives an ADR command from the server and the RAK4270 generates an ERROR 80
Payload 1

*** UPLINK COMPLETE - NO DOWNLINK ***

ERROR: 80
The RAK4270 does not process the ADR correctly !
and generates ERROR 80 after sleep command
What exactly is ERROR 80 and how should it be processed ?
Thank You
