[Bluetooth Adpater] Which Bluetooth version does my Windows computer support? Do I need a driver?

Generally, when a user connects a Bluetooth adapter to a Windows computer, it will automatically enable the corresponding Bluetooth version based on the built-in Bluetooth LMP (Link Manager Protocol) of Windows. Therefore, if the LMP is not the latest version, it may not be possible to enable BT 5.4 features.
