Gateway Details - Frames Received Vs. Frames Transmitted


I’ve got some questions regarding the charts displayed on the chirpstack web on some gateways I have connected.

They are around 5-6km apart and should have the same devices recognized by them both but the issue is that while on gateway has both frames received and transmitted, the other one only has frames received.

Is there any way I can check if this is hardware related or if its the configuration of the gateway? Both are configured the same way as far as I know. I’ve checked both ttn-gateway.service and the chirpstack-network-server.service and I can’t seem to see any issues or differences.

Thanks for your help.
