Show the distance they are in and the datarate of the lora nodes on this server

greetings to all…

how can I find out the distance of my lora nodes where they are from the gateway on this server and the datarate where they find me if they can help me please thanks

If your nodes has GPS and send the coordinates to Chirpstack in the payload, and you know the gateway coord, you can calculate the distance between them (node-gateway) inside your own application. Datarate you can find in “txInfo”: section of the endnode uplink data.
This is not a chirpstack app server task.
