Test the connection on different Ble devices using Android.
The example works on API <21 abd API >= 21.
To realize the example we started from
https://github.com/joelwass/Android-BLE-Connect-Example
that works only for API >=21 adjusting some minor bugs. For the implementation we used Android Studio 3.0.
Clone the repository and open in Android Studio.
Under the project directory run
adb install build/outputs/apk/debug/TestVleBleConnection-debug.apk
