*and some cool Java technologies!

M2M? IoT?

❝ Technology that supports wired or wireless communication between devices

Is the MQTT API that simple?

Is the MQTT API that simple? MqttClient mqttClient = new MqttClient ( "tcp://iot.eclipse.org:1883", MqttClient.generateClientId() );

mqttClient.setCallback(…);mqttClient.connect();mqttClient.subscribe("myGreenhouse/#");// the rest of your app

Is the MQTT API that simple?

mqttClient.setCallback(new MqttCallback() {@Overridepublic void messageArrived(String topic, MqttMessage message) throws Exception { // process received message // e.g. display temperature value}// ...

});

Callback code:

Data viz. w/ MQTT over Websockets

•  Rickshaw is a JavaScript toolkit for creating interactive time series graphs

•  It’s built on top of d3.js

•  MQTT over Websockets makes it very easy to feed data into Rickshaw datasets

– More at http://code.shutterstock.com/rickshaw – lots of examples to get started

In a nutshell

•  MQTT is a very versatile protocol for building your IoT solution from the ground up. You should try it!

•  Eclipse IoT has lots of projects, from basic building blocks to more complete solutions

•  We have Java, and more! J
