Hi everyone! I have a gateway connected to TTN but the data that are shown in the “live data” field are status updates. I am living in a city center, and I would expect to receive some noise from other IoT devices.
If it is indeed that quiet, I have also set up an end node with a raspberrypi zero wh + adafruit rfm95 bonnet , with LoRaPy to program the transactions:

Sending LoRaWAN message
TxDone
Even though the transactions I transmit show to be successfully sent, the gateway doesn’t show any messages on the live feed.
So it is either:
- A problem with the end node
- A problem with the gateway
- Both 1 and 2.
Is there a way to do a health check for my gateway, to see if it is possible to receive messages or if there is something else wrong?
The TTN console shows “connected”, and my journalctl -u ttn-gateway.service -f
shows no problems.
