Continuing testing of the new CycleBike Smart app for reading Bluetooth sensors. Powertap recently developed an interface for their G3 power meter hub that has both ANT+ and Bluetooth. I tested it on the trainer along with a Wahoo speed sensor that I tested before. I purposely varied the speed, and power levels. Below is a comparison of the power data from a Powertap G3 hub, and speed data from a Wahoo speed sensor. As before, the agreement between ANT+ and Bluetooth is pretty good.
