==Summary==
'''MQTT (MQ Telemetry Transport or Message Queue Telemetry Transport)''' is an ISO standard (ISO/IEC PRF 20922) publish-subscribe-based messaging protocol. It works on top of the TCP/IP protocol. It is designed for connections with remote locations where a "small code footprint" is required or the network bandwidth is limited. The publish-subscribe messaging pattern requires a message broker. This chapter is a guide on how to configure a basic MQTT setup on RUT routers.
==How MQTT works==
First lets look over how MQTT works on RUT routers. An MQTT connection takes place between two Clients and a Broker. A RUT router can be Broker, a Client or both. The MQTT Publisher (Client) present in RUT routers subscribes to two topics by default: '''router/get''' and '''get/<SERIAL>/command''', where '''<SERIAL>''' is the router's serial number.
