Here’s the latest MQTT.fx release: MQTT.fx 1.6.0!

Support for Google Cloud IoT!

A few weeks ago some guys from the Google IoT Team asked me to implement support for the all new Google Cloud IoT.

And I am very happy to announce that MQTT.fx 1.6.0 is the first client to support Google IoT Core!

Basically Google is not hosting a full MQTT Broker. They have a MQTT Bridge as a gateway to the Pub/Sub instance in the Google Cloud. You can now turn Connection Profiles into “MQTT Broker” or even “Google Cloud IoT” profiles to add all required parameters to connect and communicate to the Google MQTT / PubSub bridge (
Getting started with Google Cloud IoT).

New: Google Cloud IoT Profile

When in “Google Cloud IoT” mode, some tabs look different then in “MQTT Broker” mode. The topics are automatically prefixed with the Google Cloud IoT requirements (e.g.:
/devices/{device-id}/events). Please note that also “QoS 2” and “Retained” are not available as not supported by Google.

Modified: Publish tab

Modified: Subcribe tab
