MQTT integration with application server


I would like to know the steps to integrate the Chirpstack application server with an external MQTT broker so that I can receive uplink data from my device on this MQTT broker and initiate downlink data from the broker to the application server.

I have installed Chirpstack version 4 using docker compose. After adding application and devices I navigated to integration tab to add MQTT integration. But the MQTT panel there displays “Get certificate”. If I click on it it displays “Generate MQTT certificate”. Then if I click on “Generate certificate” I get an error on the page " Error: Read mqtt ca_cert".

How do I integrate an external broker to talk to the application and devices I have added.



MQTT integration:

Note that you will need to enable it (see [integration]):
