Prior to the AU update, my Bluetooth mouse worked fine on my SP4 I used an ISO and did a clean install. Since then, My Dell Travel mouse WM524 does not work. It pairs successfully, sometimes even shows the mouse under Bluetooth in the action center as being connected. The mouse however, continuously blinks as if it is not connected. I\’ve tried pairing, unpairing, removing device, uninstalling the mouse in device manager, restarting pc… Nothing works. Tried pairing it on my friends MacBook pro and it paired and worked fine Driver info for "Marvell AVASTAR Bluetooth Radio Adapter" shows Driver date as 2/5/16 and Driver Version as 15.68.9040.67. Is this the latest? Windows update doesn\’t show any updates. Any solutions.
