MQTT
MQTT is a machine-to-machine (M2M)/"Internet of Things" connectivity protocol.
When this protocol is selected a MQTT password, user, port, server and client ID can be
configured for use.
The TCP-IP mode should either be TCP CLIENT or WEB+CLIENT in order to operate as a
MQTT TCP client. The TReX does not support operation as an MQTT server – an external
MQTT broker must always be used.
The TReX uses a system that allows an indefinite number of IoT devices to be connected and
monitored using any MQTT phone application or software. The TReX also allows outputs to
be controlled and paging messages to be transmitted and sent as MQTT messages.
TReX units can be used as intermediate repeaters for connected sensors allowing for extremely
long range monitoring and control for IoT devices. Range is limited by the power that the
TReX is allowed to transmit at for the channel of use and how TReX repeaters have been
deployed.
While operating an MQTT IoT network, the network continues to operate normally for paging
messages, allowing notifications to be delivered to any paging receiver or TReX operating
within the MQTT IoT network.
