1.1. Features
The MQ7200M module off ers the most comprehensive configuration focused on meeting specific
application requirements. The following details the features designed to simplify installation,
configurationandapplication.
SupportforMQTTProtocol
MQTT stands for Message Queuing Telemetry Transport. It is a machinetomachine
(M2M)/"Internet of Things" connectivity protocol with extremely lightweight publish/subscribe
messagingtransport.Itisusefulformobileapplicationsbecauseofitssmallsize,lowpowerusage,

Communication Watchdog is a software function to monitor the communication between the
