Comparing ANT+ and Bluetooth data from the same bike sensor

Developing the new CycleBike Smart app to use Bluetooth sensors instead of ANT+ sensors used in CycleBike+. More Android phones have Bluetooth 4.0 than ANT+, and there are now more bike sensor choices. I'll post a blog on different Bluetooth sensors I've tried with CycleBike Smart.

But for now here's some data comparing data recorded in TrainerMode in CycleBike+ and CycleBike Smart. First, I use a Wahoo TICKR heart-rate monitor, a Wahoo speed sensor and a Wahoo cadence sensor. These sensors all have dual ANT+ and Bluetooth LE, (4.0, Smart) interface. Mounted sensors on the bike on a trainer, used CycleBike Smart on the Sony Xperia Z1 compact and CycleBike+ on the Sony Mini. Here's three charts comparing heart-rate, speed and cadence data. I had to adjust the x-axis to match-up the relative time-stamp. I also added 0.1 beats per minute to the ANT+ heart-rate data so it shows up on the plot. Since Strava-Spoofer only collects sensor data at one Hertz, the increased data rate of the ANT+ sensors is not noticed. The faster update rate can be seen on the app display. I think the data compares favorably.
