RAK7249 not receiving any RF packets

Issue: RAK7249 Gateway doesn’t seem to be receiving RF packets.

Setup: RAK7249 with SX1262 node

LoRa® Server: LoRa Basics Station

Details:

It seems like I can’t get my gateway to receive packets. I have confirmed that my node is sending messages (in this case, OTAA join requests) but no logs ever indicate that those messages are received. I also confirmed that those requests are in the frequency band that the gateway expects (ie, US915 subband 2).

The following image shows the node sending a join request every 15 seconds.

.

The only indication that the gateway’s modem seems to be working is that sometimes the basics station logs (as seen by ssh’ing into the gateway) will show a stray packet being received, but nothing regular. I’ve also not been able to inspect those packets in the GW’s web management platform.

Are there troubleshooting steps I could try to follow to get this resolved?
