Introduction

MQTT Logger captures MQTT messages and saves them into the database.

MQTT Protocol

MQTT (originally an initialism of MQ Telemetry Transport) is a lightweight, publish-subscribe network protocol that transports messages between devices. The protocol usually runs over TCP/IP, however, any network protocol that provides ordered, lossless, bi-directional connections can support MQTT. It is designed for connections with remote locations where resource constraints exist or the network bandwidth is limited.
