Continuing the comparison between Bluetooth data using the new CycleBike Smart app and ANT+ data using CycleBike+. The first chart shows, once again the good agreement between these two apps and interfaces for the power data from a Powertap G3 hub using their new dual power-cap ANT+/Bluetooth interface. The second chart shows a comparison between the speed reading from the Powertap G3 hub. Again the agreement is nearly perfect.
In the third chart I compare speed data between the Powertap G3 hub and a Biologic speed & cadence sensor (actually an Echowell BTR 099BBF Bluetooth speed & cadence sensor). The Powertap G3 speed data was recorded with ANT+ interface using CycleBike+ and the speed & cadence sensor data was recorded at the same time using CycleBike Smart. The agreement in speed data between the two sensors is very good.
