What's MQTT

MQTT stands for MQ Telemetry Transport. It is a publish/subscribe, extremely simple and lightweight messaging protocol, designed for constrained devices and low-bandwidth, high-latency or unreliable networks. The design principles are to minimise network bandwidth and device resource requirements whilst also attempting to ensure reliability and some degree of assurance of delivery. These principles also turn out to make the protocol ideal of the emerging “machine-to-machine” (M2M) or “Internet of Things” world of connected devices, and for mobile applications where bandwidth and battery power are at a premium.

How To Start

Install MQTT Broker

Testing with brokers

We use the free software mosquitto to testing. A GUI MQTT client -- MQTTBox

  • Download and install mosquitto for windows
  • Open a command line window. Change the directory to the mosquitto install directory.
  • Use the command line to check the data uploaded
mosquitto_sub -h mqtt.bconimg.com -t "/beacons"
  • Use the command line to check if MQTT broker works well. You will see "Hello World" at previous command line window if broker works.
mosquitto_pub -h mqtt.bconimg.com -t "/beacons" -m "Hello World"
