Win 10 Bluetooth driver

I have a Macbook Pro mid 2014 with Yosemite (fully up to date). I am waiting for my boot camp OS, currently Win 8.1 64 bit to update to Win 10. I have gotten a message in the get win 10 app which states that the Apple Broadcom Bluetooth Adapter on my machine is not compatible with Win 10. Is this a driver issue or a hardware issue?? If it is a driver issue, is there an updated driver available?

Thanks! Peg
