PySide6.QtMqtt¶

Detailed Description¶

The Qt MQTT modules provides classes and functions to make MQTT programming simple and portable.

MQTT is a machine-to-machine (M2M) protocol utilizing the publish-and-subscribe paradigm. Its purpose is to provide a channel with minimal communication overhead.

Generally, MQTT is used on top of a TCP connection. However, the base requirement is defined as an ordered, lossless, bidirectional connection.

The Qt MQTT module provides a standard compliant implementation of the MQTT protocol specification. It enables applications to act as telemetry displays and devices to publish telemetry data. The supported versions are MQTT 3.1, MQTT 3.1.1, and MQTT 5.0.
