Hi,
MQTT is a standard wire protocol. Software AG doesn’t provide an MQTT client, so you will need to use a 3rd party client library. The most widely used is the Eclipse Paho client: Eclipse Paho | The Eclipse Foundation
This also includes some simple samples that will also work with UM. Note that MQTT messages are binary (byte) messages, so if you want interoperability with JMS, for example, you will have to use JMS bytes messages.
I would recommend that you set up a separate interface (port) for your MQTT communication. The default port number for MQTT is 1883, so you should set up an nsp interface on port 1883 and make sure it is started (in Enterprise Manager).
Hope this helps.
