    Hi,

    I have a problem with my Lumia 2520 bluetooth drivers. Windows RT 8.1 updated all updates after starting to use the tablet. But there is left 3 unknown "probably" bluetooth devices in device manager.

    AAS
    MS-ABTP - Automatic Bluetooth Pairing Protocol
    MS-TCC - Tethering Control Channel Protocol

    I can't find theese drivers nor by automatic update drivers methode nor by manually to add them.

    I can see the hardwere ID in device manager, but nowhere to find any drivers.

    BTHENUM\{d9009112-cd2b-4e7a-a463-437d71e14905}_VID&00010006_PID&0001

    Some of the bluetooth components drivers are installed normally, so the tablet cn see other bluetooth devices and it can connect to them, but after connecting theres no file transfer are any communication between the devices , as a lumia 925 phone or Probook G2 455 laptop.

    Result is that the bluetooth isn't working properly on the Lumia 2520 Windows RT 8.1 Tablet.

    Any suggestion?

    Thank You!
