I have a single ABP device and I noticed loraserer is generating DOWNLINK UnconfirmedDataDown for every UPLINK UnconfirmedDataUp received. The device is not requesting ACK and there’s no DOWNLINK scheduled for this device, no coding / decoding functions configured at all.
The DOWNLINK is being transmitted to the air I confirmed with RTLSDR, however, the device itself is not receiving anything.
The device is a class A running on LMIC/ATMEGA328 so I set MAC ver 1.0.2 in the device profile section.
Can somebody answer what is this DOWNLINK? is it some kind of beacon used by class B or C?
