HiveMQTT neither knows nor cares what microcontroller you use - these things would all be the same irrespective of your platform.

I suggest you start by reviewing these basic principles in the HiveMQ documentation, and general MQTT documentation, tutorials, etc.

https://docs.hivemq.com/hivemq/latest/user-guide/index.html

https://mqtt.org/

Do you have basic TCP/IP working?
