  • 1. BUILDING THE INTERNET OF THINGS WITH ECLIPSE IOT* Benjamin Cabé @kartben Eclipse Foundation *and some cool Java technologies!
  • 2. M2M? IoT?
  • 3. ❝Technology that supports wired or wireless communication between devices
  • 4. fragmentation
  • 5. lock-in
  • 6. complexity
  • 7. Protocols Tools Frameworks Services
  • 8. Paho provides client implementations of the MQTT protocol. Mihini is an embedded Lua runtime providing HW abstraction and other services. Koneki provides tools for embedded Lua developers.
  • 9. Eclipse SCADA is a complete Java/ OSGi-based SCADA system (communication, monitoring, GUI, …) Kura is a Java/OSGi-based M2M container for gateways. Has support for Modbus, CANbus, MQTT, … Mosquitto is a lightweight server implementation of the MQTT and MQTT-SN protocols, written in C. (code pending)
  • 10. Ponte bridges M2M/IoT (MQTT, CoAP) protocols to the Web. SmartHome provides a complete set of services for home automation gateways. OM2M implements the ETSI M2M standard. (code pending)

  • 25. Is the MQTT API that simple?
  • 26. Is the MQTT API that simple? MqttClient mqttClient = new MqttClient
 ); mqttClient.setCallback(…); mqttClient.connect(); mqttClient.subscribe("myGreenhouse/#"); // the rest of your app
  • 27. 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:
  • 28. 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 – lots of examples to get started
  • 29. 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
