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

`MQTT <https://mqtt.org/>`_ 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.
