The Eclipse M2M (Machine-to-Machine) open source initiative delivers a stack of open source building blocks that accelerate the development of connected solutions. In this session, you’ll be briefly introduced to the Eclipse M2M projects and discover cool end-to-end examples (Augmented Reality anyone?) combining the use of Android API with Open Hardware platforms (Arduino, Raspberry Pi…) for doing fleet tracking, remote monitoring, home automation, and much more.

public void messageArrived(String topic,
MqttMessage message)
throws Exception {
// process received message
// e.g. display temperature value
}
// ...
});

@Override
public void messageArrived(String topic,
MqttMessage message)
throws Exception {
// process received message

}
// ...
});

42. Simple but not Stupid
• QoS
– at most once, at least once, exactly once, …
• “Last will & Testament”
– automatically publish a message when a client
goes offline
