SecurityException when starting a scan with PendingIntent

[dariuszseweryn]

When calling BackgroundScanner.scanBleDeviceInBackground() the below error may be thrown:

java.lang.SecurityException: Need BLUETOOTH_PRIVILEGED permission: Neither user 10188 nor current process has android.permission.BLUETOOTH_PRIVILEGED.

It seems that the Android OS for certain settings needs BLUETOOTH_PRIVILIGED permission

This ticket is invalid as this situation to happen needs a use of SystemApi or calling the API when the Bluetooth is not on which was fixed recently
