Hi Yuan,

Are you working with a VANTIQ edge node on your laptop?  Is there an MQTT broker running at on your laptop or edge node?  Only in this circumstance will you be able to communicate with a MQTT broker running locally at  If you are testing the source with a VANTIQ cloud then “localhost” does not have much meaning – it means something that is “local” to the cloud servers

Vantiq maintains its own broker that you can publish and subscribe to:
Server URI: tcp://public.vantiq.com:1883
Topic: com.vantiq.sensor.sample

After you create a SOURCE with the above properties you can click on Test Data Receipt and you should see test data being read for id (id), timestamp (ts) and voltagelevel (vl).
