19. WHAT IS ZE BEST
LANGUAGE FOR
IOT?!?
I often get asked…
20. ANSWER: It depends! J
For embedded systems…
Codevs.Configuration
Constrained micro-controllers vs. Smart gateways
C
Javascript
Lua
Java/OSGi
21. ANSWER: It depends! J
Infrastructurevs.App.development
Communication enablement vs. Information systems
On the server side…
C
Javascript
Java/OSGi

31. 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
32. Is the MQTT API that simple?
mqttClient.setCallback(new MqttCallback() {
@Override
public void messageArrived(String topic,
MqttMessage message)
throws Exception {
// process received message
// e.g. display temperature value
}
// ...
});
Callback code:
33. 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
34. 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
