"Removed need for pairing on Windows to discover and connect" - inaccurate ?

Hi.

The page at https://wiki.qt.io/New_Features_in_Qt_5.13 claims that Bluetooth pairing is no longer needed on Windows to discover and connect.

I cannot replicate the above.

Host config:

• Windows 10 Version 1809 (build 17763.678)
• Avantree DG40S USB Bluetooth 4.0 Adapter Dongle
• Qt 5.13.0 MSVC 2017 64 bit

Observations:

1. Windows 10 is able to discover all my devices (iOS 12.4, iOS 10.3.3, Android 5.0.2, Windows 10 ) and also many unknown neighboring devices.

2. Scanning with QBluetoothDeviceDiscoveryAgent discovers some of the unknown neighboring devices but none of my devices.

3. The moment I pair my devices with my host system, QBluetoothDeviceDiscoveryAgent successfully discovers them.
