This is an MQTT client and test tool. MQTT is a machine-to-machine (M2M) messaging protocol commonly used for IoT applications. For more information on MQTT visit http://mqtt.org
MQTTool can connect to authenticated and unauthenticated MQTT brokers, subscribe to topics, and publish messages to topics.
I built this tool as i was doing my own MQTT investigations and I've posted it hoping others would find it useful too. I continue to use it on projects, and I'm continuing to look to improve this tool. If there are changes that would make this more useful, please send me feedback. Thanks!
