The MQTT (Message Queuing Telemetry Transport) protocol is an open
network protocol for machine-to-machine communication, which provides the
transmission of telemetric data messages between devices. The integrated
MQTT client allows the device to publish a specific set of information to an
MQTT broker.
The publishing of messages can either occur periodically or be triggered
manually.
10.1.1 MQTT configuration
The MQTT client can be configured either using the Web interface or directly
via a JSON object sent in an HTTP request. For more information see chapter
MQTT configuration - Quick start guide
on page 102.
The configuration URL is:
http://[ip-address]/w/config/mqtt.json
The configuration can also read back as a JSON file:
http://[ip-address]/r/config/mqtt.json
The configuration is a JSON object. Each member is a configuration element.
The object must not contain all elements. Only the provided elements will be
changed. The configuration changes apply only after a device restart.
