Does CABLE allow control of resistance based training devices?

CABLE supports the BLE Fitness Machine Service (FTMS) for controlling controllable ANT+ FE-C and ANT Saris CycleOps trainers.

The fitness application on the mobile device needs to support FTMS for the feature to work. The current list of supported apps is Zwift, TrainerRoad, The Sufferfest, Fulgaz, Kinomap, Wahoo etc.  Other applications are in the works.  If you want to use the FTMS service for your FE-C device, you should connect the FE-C ANT+ profile or the Saris data service to the FTMS BLE service using the CABLE Util app.
