I like the world choice implementation. The Windows 10 Bluetooth trainer control however didn’t work well for me.
I had 3 “No signal” drops from the Kickr 16 during a 16 mile ride which left me stranded on the side of the road with no power. I was able to unpair/re-pair the Kickr in each case and resume the ride, only to have it drop again later. Meanwhile the Wahoo Tickr and cadence sensor maintained their BT connection for the full ride with no issues at all. Then to add to the fun, Zwift froze when saving the ride. It was only one ride, but I’m already certain I won’t use BT trainer control on any real workout or group ride, it’s too unreliable for me. I’m using Windows 10 1809 with BT 4.1 if that matters.
The good news is that the BT connection (when working) seemed much smoother on gradient changes and didn’t suffer as much latency as the ANT+ trainer connection. I’m not sure why that’s the case, but that’s what it felt like to me. So if BT can be made stable on Windows 10, I’ll definitely prefer it.
