MQTT

MQTT is an OASIS standard messaging protocol for the Internet of Things (IoT). It is designed as an extremely lightweight publish/subscribe messaging transport that is ideal for connecting remote devices with a small code footprint and minimal network bandwidth. MQTT today is used in a wide variety of industries, such as automotive, manufacturing, telecommunications, oil and gas, etc.

Apica Ascent can act as an MQTT broker to receive MQTT messages from IoT clients.

PRE-REQUISITE

In order to enable this integration, Fluent Bit to MQTT must first be in place.

Sending MQTT messages to Apica Ascent

Once the pre-requisite is in place, Apica Ascent uses the 1883 port to receive MQTT messages. Connectivity can be tested using the following mosquitto_pub command:

mosquitto_pub -h endpoint.ascenthost.com -p 1883 -t temperature -m '{"device_version": "v11", "temp": 92}'

Apica Ascent uses the incoming topic name from the messages to partition the data by default. This behavior is customizable.
