Kickr Bick Shift: Garmin settings "wheel size" and "gear ratio"

Hello,

I just did the setup of my Kickr Bick Shift and in my Garmin (FR955) the settings sensors>smart trainer> “wheel size”, “gear ratio” and “bike weight” should be set to what?

Also I see the Garmin watch only connect to the smart trainer through ANT, isn’t possible to force Bluetooth?

Thanks,
