I am making an android application that requires me to detect the user's motion. My application also requires me to use an external sensor, which is a Bluetooth smart sensor, for some other purposes.
Now I have two options:
- to use the accelerometer and gyrometer of the android phone
- fetch motion information from the bluetooth smart sensor.
I understand that Bluetooth Smart (ble) is more energy efficient than Bluetooth sensors.
However, I am confused as to which of the above options will provide me a more energy efficient solution on the Android device. EDIT: I am presently not concerned with the energy efficiency of the bluetooth device. Also, please see that I want this comparison only because I don't want to detect accurate user motion, otherwise an external device(bluetooth low energy device) would have been better hands down.
