I bourght a used BKool 2015 trainer pro.
When swift serches. it’s able to fin my Ant+ hartrate strap, but not the trainer.
I quite sure the trainer has been updated, as it dosen’t popup with a firmwhare update, and there is a ant+ icon beside the trainer and heartrate strap in the parring settings (BKool).
The trainer seems to have Ant+ support. I have no problems in the Bkool software connecting to trainer and strap.
See attached picture.
We have a complete article on how to connect your Bkool trainer to Zwift. I highly recommend going through our Knowledge Base as it contains a ton of information and answers
To the right of the trainer, in your screenshot, just to the left of the check mark, click the open space. A box will appear where you can check ant+fe-c. It’s invisible at first. Took me a while to stumble upon it. Then your trainer will work with swift.
