As you may have noticed from the Python sample script PointPerfect MQTT Client we provide, it serves as a reference code to aid in the evaluation of our solution. However, we do not distribute MQTT Client code that can be integrated directly into the final product.
The Python script employs an external open-source MQTT library (paho-mqtt), and to achieve similar results in C/C++, you would need to obtain the appropriate version of paho-mqtt (which is readily available for most languages and platforms on github) and then port the Python code that exercises the MQTT client to the desired language. Unfortunately, we do not offer this service, and it would be necessary for you to perform the porting yourself.
