On the WattBike Trainer (old version of the Air, I think) at the gym the power sensor is read reliably over Bluetooth. However, the cadence sensor is never found. Oddly, TP Virtual does find a couple of cadence sensors for rowers in the gym nearby. Additionally, my Coros watch correctly picks up cadence from the Wattbike. In turn this tells me the scan for cadence is working, and the Wattbike is broadcasting cadence data. It's just that TP Virtual is not picking this up.
