Setup: Wattbike Atom (firmware version 1.02.1), Windows 10 version 1909, connection via Bluetooth
Good: Pairing is all fine via Bluetooth to my Atom for Power Source, Cadence and Controllable.
Not Good: When using a workout in ERG mode, even though the Zwift app in windows states I am in ERG mode (by stopping to peddle I get the ERG mode temporarily deactivating and then reactivates when I start peddling again so Zwift thinks all is fine). However, there are no resistance changes while peddling. I can change gear on the Atom which I would not expect when in ERG mode.
Note, if I use the companion app instead of Bluetooth from the windows machine or even use the Android app, everything works as expected, i.e. resistance changes to keep to the power target and changing gear on the Atom has no effect.
This appears to be a bug in the Windows App for Bluetooth only and specifically for controlling the resistance.
Is this a bug? Is there a workaround or a fix? Any help will be very much appreciated.
