I have discovered the LinkADRReq commands aren’t being processed properly by the RN2903. After a factory reset and join, the RN2903 appears to be ignoring the first ADR mac command. Upon receiving the second downlink with the LinkADRReq, as you will see below, the RN2903 appears to be setting the channels in a strange way, completely unexpected. I hesitate to say the channels are being set randomly, because the channels are set the exact same way each time.
I have seen the ADR commands work fine with the 2903, but then they mysteriously stopped. If I switch to TTN, the channels are set properly.
In the capture below, it appears the mac command payload is right, but the 2903 channels aren’t getting set properly.
In the following capture is the 2nd ADR downlink, the first hex value is last part of the deveui, the next 3 hex values are the clock.) The mac commands are being displayed by a debug version of the firmware version 1.0.5.
The payload appears to be:
03 00 0000 70 (all channels off)
03 31 00FF 11 (subband 2 on, is that one transmission or 1 repeat- nbTrans or nbRep?)
05 0A (RX param DR offset 0, DR 10)
