Hello,

we are currently building a demo using EFM and we want to connect our sensor devices to the EFM Broker.

Our devices send their data via MQTT to a Mosquitto broker on the same machine the EFM Broker is running on.

How do we connect the Mosquitto Broker as a downstream to the EFM Broker?

We tried to use the MQTT DS-Link and set the the broker variable in the configuration to http://127.0.0.1:1883 but when we start the link the state switches between started and stopped.

The log of the test DS link:
