Location needs to be enabled for Bluetooth Low Energy Scanning on Android 6.0

Question

After upgrading to Android version 6.0 Bluetooth Low Energy (BLE) scanning will only work if Location services are enabled on the device. See here for reference: Bluetooth L

Answer 1

You can use BluetoothAdapter.startDiscovery().
It will scan for both Bluetooth Smart and classic Bluetooth devices, but location services do not need to be enabled.
(You still need ACCESS_COARSE_LOCATION permissions on Android 6.)

You can call BluetoothDevice.getType on found devices to filter for Bluetooth Smart / Low Energy devices.
