android bluetoothadapter.startLeScan, filter by UUID

问题:

I want to scan BLE device with the startLeScan(UUID[] serviceUuids, LeScanCallback callback) method, now I have a UUID, it's a 16-bits value, for example, 00000000-0000-1000-8000-00805F9B34FB.

How can I use the UUID in startLeScan method, I write like this,

UUID[] uuid = new UUID[1]; uuid[0] = UUID.fromString("00000000-0000-1000-8000-00805F9B34FB"); mBluetoothAdapter.startLeScan(uuid, mLeScanCallback); 

But finally I can scan nothing. How can I resolve this problem.
