It cannot find the Polar H9 via Ant+ anymore (since the latest Update?, it worked last season). Only Bluetooth but this strap has only 1 BT connection.
BT available: shows HRM, but with unknown Ant+ id
BT unavailable: nothing found
Searching on device via button same behaviour.
A Garmin strap is found via both channels, Kickr also. But the Polar strap is also found via Ant+ by other devices like Hammerhead and Garmin units.
Everything is unpaired. That screenshot is the search and should only show the situation with unknown id and that it finds the Garmin. But sometimes it also has problems with the Garmin:
Oooh my bad I didn’t realize which screen that was.
One thing I’ve found helps with the Headwind, particularly for firmware updates, is to physically stand further away from the unit to slow down the connection. Once I’ve got everything paired it works fine up close. Honestly can’t think of anything else.
