Description
I'm developing new BT LE Examples using QtQuickControls 2 and all the new BT LE stuff from 5.7/5.8
Will provide soon at Github Example with Scanner and Heartrate
While developing the BT LE Scanner I had a problem with a BTLE Waiter Lock (Magnetic Key put in sends ID, pull out sends message)
This Device also contains a HID Service. Trying to get the details I run into a Stacktrace calling QLowEnergyService.discoverDetails()
W QtBluetoothGatt: Performing queued job, handle: 22 Read (false) ValueKnown: false Skipping: false Characteristic W QtBluetoothGatt: Performing queued job, handle: 23 Read (false) ValueKnown: false Skipping: true CharacteristicValue W QtBluetoothGatt: Performing queued job, handle: 24 Read (false) ValueKnown: false Skipping: false Descriptor W BluetoothGatt: Unhandled exception in callback W BluetoothGatt: java.lang.SecurityException: Need BLUETOOTH_PRIVILEGED permission: Neither user 10135 nor current process has android.permission.BLUETOOTH_PRIVILEGED.

state is hanging on:
QLowEnergyService::ServiceState(DiscoveringServices)
my workaround: trying to get details for serviceUuid "0x1812" user gets message that HID Service isn't supported yet by my App
