Cadence
I use a power meter for recording cadence and power but I get loads of cadence dropouts so the watts also drop. Need to improve the connectivity of cadence to prevent dropouts.
Many thanks for letting us know about this, and your support for TrainingPeaks Virtual.
Dropouts are nearly always a result of radio-interference in your room (i.e. the Bluetooth signal from your device to your computer is swamped with noise from other sources - perhaps someone running a microwave oven nearby etc).
As such, this isn't anything that can be fixed in TrainingPeaks Virtual, and instead is something that would need to be addressed by positioning your devices and computer in a way that doesn't get impacted as much by your environment.
