It would also be helpful to see a wireshark log of what the device is actually doing.

Windows is protective of some well-known services/characteristics and won't allow accessing them. Similarly, BlueZ hides the GAP Service completely, making the device name inaccessible. Furthermore, the device name displayed by...

I do not understand the issue. Can you give a fully reproducible test case?
