Hi, Amaroo 2921
Welcome to the MicroSoft Community.
Thank you very much for your generosity in sharing the problems you found and their solutions. I appreciate your contribution to community content building and your sharing is a valuable experience for the Microsoft community. For these types of issues that really aren't easy to get to, I tend to consider the Bluetooth adapter driver as the cause, and the Bluetooth 4.0 dongle is really a much more intuitive solution.
If you have good ideas about the Windows experience you encountered, please feel free to share them with the Microsoft community, it will help more users who are facing the same problem.
Best Regards
Martin | Microsoft Community Support Specialist
