After upgrading to Win 8.1, The Bluetooth in the system is not working. It was fine in Win 8.
I installed the latest Mediatek drivers (SP65235), and Bluetooth installs, but does not fully pair with my headset or with my mobile.
I check the Ralink folder under Program files (x86), and I see only one folder Program Files, but not all the the other software or drivers required for bluetooth to work properly. I have reinstalled many times, but the same issue.
Need help ....
My PC is
Model # : HP Pavilion 15-n006ax Notebook PC (ENERGY STAR)
Wireless : Ralink RT3290 (Wireless as well as Bluetooth)
From what I have read over, you do have the latest driver available for the Mediatek Bluetooth driver. I would suggest running through the document 'Using Bluetooth Devices (Windows 😎', as some times the Bluetooth connection can be a little picky. Now if you are still not able to pair Bluetooth devices, I would suggest the document 'Fixing Bluetooth Problems'. Now I know that some of the steps in this document are for Windows 7, but still can be used for Windows 8.1.
Please let me know how the above steps have worked for you.
