Sigh. I am in ANT/Bluetooth purgatory right now.
I bought a Bluetooth dongle. Zwift doesn't do Bluetooth, at least on Windows. It wasn't much, but that thing is going to end up in my desk drawer.
I bought an ANT dongle. Tried it out on my laptop. Very intermittent - barely works, really. I can occasionally get the thing to recognize it, but you bump something and it goes right out again. So that's going to have to go back to Amazon, and get a replacement from somewhere.
I was going to use BlueSC as the cadence sensor. And I now realize that this thing is Bluetooth only. So that's not going to work. That goes back in the desk drawer as well.
Zwift on Windows is ANT-only. Although in theory one can use the phone as a Bluetooth/ANT bridge if you install the Zwift app on your phone. But Bluetooth on my Android 6.0.1 phon isn't working properly with BlueSC or the Kickr, so that's not a good option.
While the laptop is somewhat underpowered for Zwift, I can launch the thing and sit and watch from the sidelines. The graphics doesn't stutter, which I guess is good, at least for now. That's the only positive thing to come out of this, I guess.
I suspect the Kickr and the Tickr will connect fine with ANT, once I have a working dongle. So for now I guess I drive it all from the Bolt (which probably would recognize the BlueSC as a cadence sensor).
