Trere are few things I am willing to try. First of all check the Sony Bluetooth drivers. 13" flip model uses the same adapter. I know for a fact Sony uses october release drivers as a part of the driver package. then I am planning to check Dell drivers and installation package. Dell uses the same board on a XPS model and it works really well.
I also ordered new Broadcom adapter to rule out hardware issue and go from there. My adapter does work right now
as long as I do not reboot the laptop. I had to remove all broadcom dravers and associations. and after that driver loads with no problems. I'll be out on vacation for the next two weeks. Hopefully Intel will release a new BT driver package by then. They 've been promising to release a new set for a few month now and if this is does not work I am not planning to go above and beyoung fixing someone's screwups, if the Broadcom adapter will work I'll toss this one in a garbage and forget the whole thing.
