==How MQTT works==

First lets look over how MQTT works on RUT9xx ~~and~~ RUTx 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. When a third party client connects to the Broker, it sends the message '''id''' to the the topic '''router/get'''. The publisher then sends a response containing its serial number to the topic '''router/id'''. Now that the Client knows the router's serial number it can ask for values of various parameters by sending requests to the topic '''router/<SERIAL>/parameter_name'''. The MQTT Publisher can send responses containing values of these system parameters:
