BKool trainers may require you to update or install the FE-C software to enable The Sufferfest App to connect to your trainer. You will need to load up the BKool App and create an account. Then, just follow the steps below. If you do not see BKool broadcasting an FE-C sensor in the power connection of The Sufferfest App, then you will need to follow these steps.
*BKool users, make sure you are using the BKool app version 3.53. The previous version of the app will not let users turn on the FE-C connection for your BKool trainers*
Once you create an account with BKool, go to the settings tab:
Then, select pair my devices.
The last thing you will do is select Switch to ANT+ FE-C.
After that, just full close down the BKool App and then open up the Sufferfest Training App. You can now head in and start connecting devices: Starting Your First Workout.
