MQTT

Message Queuing Telemetry Transport (MQTT) is a publish/subscribe messaging protocol for use over TCP/IP. MQTT is designed to ensure that devices can communicate with each other while minimizing power and bandwidth requirements. It is a simple messaging protocol that is well-suited for use with devices that rely on slow or unreliable networks.

The MQTT protocol is an application layer specification and has been published as standard ISO/IEC 20922. MQTT uses a Publish-Subscribe mechanism which requires a mediating broker. In this release, as a subscriber, the MQTT Communication Driver will subscribe MQTT payload of Sparkplug, JSON, and/or plain text format. As a publisher, the MQTT Communication Driver will publish data in Sparkplug and JSON format.
