The Sufferfest guidance for the Windows app is " Most USB BT dongles do not seem to work consistently, so we do not recommend them"
So I realize I’m not taking suggested path. But still, my BT dongle works with 100% reliability on Zwift and TrainerRoad. And it eventually works with Sufferfest, there’s always just a bit of drama for Sufferfest. About 2/3 of the time I start a session some combination of my 3 BT devices (Tacx Neo II, Polar H10, Power2Max PM) either won’t show up, or won’t show up with the full set of advertised capabilities. If I “remove” and add them back, they’ll eventually show up correctly. It just adds about a minute to my workout setup, which is slightly cumbersome.
I’ve checked the obvious things, like making sure those other applications are completely shut down, etc.
Am I alone here, or are others seeing this? I’d just take the Sufferfest warning at face value, except Zwift and TrainerRoad are drop-dead reliable.
