Subscription to AirVantage MQTT topic

Question

Hello people!

I'm having difficulties with MQTT.

Did anyone manage to "subscribe" to AirVantage MQTT server?

I never used a MQTT so I'm getting some difficulties when I try to get notifications when new data is published to AirVantage. Maybe I'm missing the point here? Should I get the updated values if I subscribe to some topic?

I call subscribe with MQTTLens or Paho test client but nothing happens after I publish new data (subscription to <SERIAL>/tasks/json appears to be successful). And I'm sure data is being published because I can see new values on Monitor -> Systems page in AirVantage control panel.

Hope someone can help.

To retrieve the data you sent to AirVantage, your application shall use the AirVantage REST APIs. A tutorial is available here: https://doc.airvantage.net/display/USERGUIDE/Use+AirVantage+API Example: to list historical values you sent to the system: GET https://na.airvantage.net/api/v1/systems/data/raw?targetIds= {system_uid}&dataIds=machine.temperature, machine.humidity&access_token={token}

No, the REST API to access AirVantage is decoupled from the device protocols: you can send data to the Cloud with MQTT or REST, to access the data you must use REST.

Hi Dragan, I hope to be able to send some MQTT data to AirVantage this weekend. Will update you once I figure it out Frederick
