I’m not sure what sort of tools you are looking for in this case. E.g. tools like tcpdump and telnet are included.
However, it seems you are having issues receiving data from your devices. In that case I would:
- Look at the Concentratord logs to check if your gateway is receiving data from your devices
- Subscribe to the “gateway/#” topic to see if this data is published over MQTT
- Check the ChirpStack Network Server logs for any errors
- Check the ChirpStack Application Server logs for any errors
Even when the device hasn’t been properly configured within ChirpStack, data should appear on the frame logs page of the gateway (web-interface).
Connecting a gateway - ChirpStack open-source LoRaWAN<sup>®</sup> Network Server might be helpful as well.
