It’s IoT Time: Hacking the MQTT protocol
Thursday June 22nd codecentric will host once again a hands-on meetup: “It’s IoT Time: Hacking the MQTT protocol”, presented to you by our codecentric colleagues Jens Deters and Jochen Mader. We are thrilled to welcome them again at our office and this promises to be a great coding session once again. Bring your own laptop, with Java and Maven already installed.
17:30 Doors open
18:00 Food (pizza)
18:30 Presentation and hands-on programming; It’s IoT Time: Hacking the MQTT protocol
The Internet of Things becomes more and more part of our life. A fast growing number of different kind of devices provide programming interfaces. The more heterogeneous these environments are, the more increases the need for consistent transmission and control protocols. By end of the 1990s IBM invented the Message Queue Telemetry Transport called MQTT.MQTT is a very lightweight, easy to use “publish/subscribe ” M2M / IoT communication protocol that rapidly gains importance in the IoT ecosystem. Jochen and Jens will do a thorough introduction into the inner works of MQTT and Vert.x.Jens will start with a through MQTT introduction including MQTT.fx – a tool for testing, simulating, and debugging MQTT communications. Then Jochen will talk about Vert.x and its recently released MQTT-server. After this block of theory we will then dive into creating our first MQTT-Vert.x-Application to interact with microcontroller driven sensors.
We will touch the following topics:
– Inside MQTT
– the standard industry protocol for the IoT
– Overview of the very active MQTT ecosystem
– Introducing MQTT.fx
– Vert.x core concepts
– Putting vert.x-Apps into fat-jars and docker
– creating a Vert.x-cluster and connecting it to MQTT-Sensors
