MQTT
MQTT (Message Queue Telemetry Transport) is a communication protocol with a strong focus on a small data footprint.
Therefore, it is perfect for communication between lightweight devices (such as microcontrollers like the ESP8266). MQTT generally runs on TCP/IP, but there is also an extension (MQTT-SN), which can be used on non-TCP networks. Further information can of course be found on Wikipedia, mqtt.org or - if you require german information - Informatik-Aktuell published a nice introduction article.
Broker
Since MQTT follows a client/server architecture, a central server is needed in order to publish messages and to subscribe to messages. This server is called broker. Since MQTT is an open protocol, multiple implementations exist, which have been compared on Github.
Client usage
As mentioned, MQTT is designed to run on a broad variety of devices. As of this, implementations exist for microcontrollers, regular PCs as well as smartphones.
If you want to integrate MQTT in your project, please check the selection of client libraries on Github.
For anything using the Arduino IDE, please also see the library provided by adafruit AdafruitMQTT
If you want to "just use" MQTT on your device and check the messages in our network, please see this article.
CoMakingSpace Implementation
We will add a MQTT Broker into our Network in order to enable IoT devices to easily communicate with each other and send / receive messages (such as status updates).
Our implementation runs on the same Raspberry_Pi, which also hosts Project:Music Station sitting in the Common Room. Therefore, the hostname is comakingcontroller (having a fix IP: 192.168.1.2). It offers its services on the standard MQTT port: 1883.
The following projects use - or will use the MQTT Broker: Project: Enhanced Door Bell
