Hello. Is there any possibility to define custom topic format & JSON payload (like it is already possible with the „JS codec function“ for LoRa frames) of the Chirp Stack Application server. Currently, the topic format is (https://www.chirpstack.io/application-server/integrate/sending-receiving/mqtt/ ) integrated with MQTT and I want it to integrate it for OGC SensorThings API format (http://docs.opengeospatial.org/is/15-078r6/15-078r6.html). So, therefore, I need to change the topic format and JSON payload of the chirp stack application server. Any help would be highly appreciated. Thank you
You can change the topic template in the
chirpstack-application-server.toml file, but then that applies to all devices. You can not change the JSON format.
I think it is better (on the short term at least) to implement a bridge which either consumes from MQTT or HTTP and transforms this into the wanted data-format.
