I have a RAK831 RaspberryPi 3B+ gateway. The gateway appears to be talking to TTN successfully, concluding as much by the green “Connected” status in the TTN Console.
I have configured an Application and Device in TTN with what I believe are the appropriate values, primary considering I expect being the Device EUI which does match the EUI printed on the device.
The problem is that the device is still showing as “never seen” and I am not seeing any errors in the logs I’m aware of:
/var/log/syslog/lora-app-server (which is empty)
/var/log/syslog/lora-gateway-bridge (which is empty)
/var/log/syslog/loraserver (which is empty)
Tailing the syslog while triggering the device I don’t see any change in log output corresponding to supposded device activity.Doing a tcpdump I see consistent ongoing output irrespective of device activity.
How can I debug the connectivity of the device to confirm if the problem is between device and gateway or between the gateway and TTN, or to get more information about what the LoRa antenna is/isn’t receiving?
The syslog has times that it says there are packets to send upstream however I’m not clear on the correct interpretation of “upstream” in this case.
