A demo sketch that carries Bosch's BMA250 accelerometer data over BLE specifically for the TinyDuino BLE shield and accelerometer shield.
The sketch is available here: Sketch
An android app for it is available here: App
Note the app was designed for a more complex sketch, therefore all the functions in the app such as "Sample Rate" and "Frequency Sweep" will not be available. You can still export accelerometer data from the app to the phone's SD Card however.
Have fun!
