I have a similar problem. I received recurring messages from the Windows Action Center that there was a problem with my Bluetooth. I clicked on the notifications and was prompted to download and install Qualcomm Atheros Bluetooth Software V8.0.1.316_x64_Win8_Win8.1. Since installing my PC no longer connects to any of my Bluetooth devices. The Bluetooth icon appears correctly in the system tray. If I go to Bluetooth settings, each device shows not connected. If I try to add a new device, the system doesn't detect any.
After hours of searching on my own then on hold and with service personnel at Dell, we determined that the Atheros Bluetooth Software V8.0.1.316_x64_Win8_Win8.1 is not in fact compatible with Windows 8.1.
I can't uninstall the package. When I try to do so, Windows tells me that I am trying to "install" software that is not compatible with my verison of Windows. I'm trapped.
Dell is telling me that the solution is to roll back to Windows 8. I'm not willing to do this. I upgraded back in the spring and who knows how much hassle the change will incur for me.
This all really stinks. Microsoft made a miscalculation that people would give up their keyboards and mice in favor of a "Next Generation" interface. Windows 8.0 was their answer. Windows 8.1 was their reaction to the marketplace failure of Win 8. The problem is that Microsoft doesn't live in a vacuum. A large part of their success is the ecosystem of other vendors who write drivers, applications and add ons to their products. They seem to have failed to consider (or don't care about) the chain of reaction of lost productivity they have caused because these vendors didn't step to Microsoft's cadence.
I'm not sure what to do except live without Bluetooth until someone comes to their senses and fixes this problem. We are not alone. Across the globe there are many people dealing with
this same issues. I hope Microsoft learns how mad we are at this enormous inconvenience. Frankly though, I don't think they care about their consumers inconveniences.
