Windows 10, bluetooth Midi

Hi,
I've bought 1 off Yamaha ud-bt01 and md-bt01
Windows 10 ( fall 1699.15 build) sees them ok and they appear in cakewalk devices.
However if I select them and hit apply, the program hangs until terminated. Any help gratefully received.
Also if your thinking of buying one of these be aware that the ONLY way to update the firmware and Name the port ( in the device not sonar) is by an APPLE config app.
There is no windows or andriod app available.
Regards
Damian
