===Configuring SBC Lynx as a MQTT broker===
TBDThis example shows how to install a MQTT broker on SBC Lynx, running Debian distribution. "MQTT, a simple, lightweight, publish/subscribe messaging protocol on top of the TCP/IP protocol, is the ideal protocol for the emerging IoT world" [1] and is becoming one on the most common protocols used for machine-to-machine communications. MQTT is based on a publish/subscribe model, as depicted in the following image. This makes it suitable for "Internet of Things" messaging where even highly constrained devices are used (low power sensors, mobile devices, embedded computers, microcontrollers, etc.).[[File:MQTT-architecture.png|thumb|center|600px]]For more details, please refer to the publicly available resource such as [http://www.steves-internet-guide.com/mqtt/ this link].
