How to retrieve list of Application IDs

ChirpStack (v4)
1

I have a system with Chirpstack v4 and a couple end devices. I have been able to use MQTT to subscribe and monitor up-link events from the devices. I can also with a separate program, generate down-link packets to the device ( since I got the application ID from the GUI to integrate into the topic name).

What I am wondering is if there is a method to get the list of active AppIDs via MQTT, other than just waiting for an uplink to occur first.

It’s not possible through MQTT, I believe scheduling a downlink is the only MQTT “command”. You could use the gRPC API though, there isn’t a specific command for what you’re asking but you could definitely accomplish it through the API.
