Exercise

MQTT single message

Imagine the following scenario: You have been given an MQTT Broker address and a topic name, and you are supposed to write some code to store the contents of the Datastream.

First, you should check what format the messages will be in by consuming a single message.

You can then print and inspect the message to determine how to process the data further.

This will be our basis for the next exercise, where we will be subscribing to the data stream and collecting multiple messages.
