I am running Chirpstack v4.3.2.
On Gateway side I have RPI CM4 running ChirpStack Gateway OS. I was surprised by the simplicity and functionality of the GW GUI configurator. Thing just works right out of the box.
I have configured GW to connect with the server over MQTT. It works just fine. Now I want to send some metadata of the gateway together with the standard stats. As I understand it should be done via chirpstack-mqtt-forwarder.toml config file
Probably it would be better to integrate this into the web-interface. The generated configuration changes are stored under /var/etc/chirpstack-mqtt-forwarder, however the content in this folder is re-generated on each restart of the service thus your changes will be immediately overwritten…
