Pairing Win 7 & Samsung Galaxy Tab S2 via Bluetooth

Has anyone else tried to pair via Bluetooth a Win 7 PC, Ultimate Edition
if it matters, and a Samsung Galaxy Tab S2 SM-T719, LTE edition? I can
link the two by USB cable, and copy data between the two, but now I have
a potential need to link the two by Bluetooth.

I authenticate between the two successfully, but then W7 complains that
it doesn't have drivers for three new devices labelled ...
Bluetooth Peripheral Device
.... and that it can't find them by searching the web. There are no
drivers on the Samsung support page for that device:

I've tried ringing Samsung support, but got a thicko who couldn't
understand why I would be ringing Samsung mobile support for Windows
drivers, and who wanted to transfer me to their Windows support, but I
wouldn't let him, saying that I had a Samsung tablet, not a Samsung PC.
Finally, he gave an email address for their technical support helpdesk,
I've emailed them, and received an acknowledgement, but as yet no useful
help.

In the meantime, has anyone else come up against this sort of problem
when pairing a W7 PC and a Samsung mobile, and can they suggest anything
to help?

TIA
