It should be possible to stream ANT+ sensor to MATLAB or Python, which support MQTT .
1. Example code from Reto:
2. install a MQTT brocker on the Rasperri:
3. Connect to RPi 3 ad-hoc network from windows PC:
4. Connect to Matlab MQTT:
5. connect to Matlab example code:
6. Or connect to Python MQTT:
