Add this permission to the manifest file to use Bluetooth features in your application:

<uses-permission android:name="android.permission.BLUETOOTH" />

If you need to initiate device discovery or manipulate Bluetooth settings, you also need to add this permission:

<uses-permission android:name="android.permission.BLUETOOTH_ADMIN" />

Targetting Android API level 23 and above, will require location access:

<!-- OR -->
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
