Hi John,
Only the source for the ANT+ Demo is available. However, if you sign up as an ANT+ Adopter you can download the necessary ANT+ Profile documentation which gives you all the information you need to receive speed and cadence information. See the
implementing a device profile page.
The ANT+ demo shows you how to configure your channels and parse ANT messages, so you simply need to modify this to configure the channels and parse the messages as described in each profile document.
