DL-300 Data Logger User Manual Version 1.1.0 Aug. 2015

- 32 -

4.5 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 Publish-Subscribe messaging pattern requires a message broker. The broker is

responsible for distributing messages to interested clients based on the topic of a

message. Now the MQTT Version 3.1.1 becomes an OASIS standard, it is an ideal

protocol for communicating with connected devices in the emerging

"machine-to-machine" (M2M) and "Internet of Things" applications, and for mobile

applications where bandwidth and battery power are at a premium.

Input the IP address and port number for the MQTT broker and click on the

Update

Settings

button to save the parameters.
