Switch BT adapter

[RCOO]

I've got an Atheros AR9285 which provides Bluetooth and Wifi on my setup.

The BT version is inferior to 4.0, however.

I've got an Asus BT-400 dongle, and I would like to disable the built-in Bluetooth and switch to the dongle to have the continuity feature.

Bluetooth Explorer does not switch the adapter (it fails and the built-in remains active).

And my DSDT: http://cl.ly/050r3k1e3F2F

 

Can anyone help me achieve this?

Thanks

Hi,

 

In the DSDT you could try to disable the BT device: 

Change: 

                Device (BT)
                {
                    Name (_HID, "TOS6205")  // _HID: Hardware ID
                    Name (BTWK, Zero)
                    Method (_STA, 0, NotSerialized)  // _STA: Status
                    {
                        If (LNotEqual (PIDC (0x19), Ones))
                        {
                            If (BTON)
                            {
                                Return (0x0F)
                            }
                            Else
                            {
                                Return (Zero)
                            }
                        }
                        Else
                        {
                            Return (Zero)
                        }
                    }

                    Method (DUSB, 0, NotSerialized)
                    {
                        Store (Zero, ^^PCI0.LPCB.EC0.BTDT)
                    }

                    Method (AUSB, 0, NotSerialized)
                    {
                        Store (One, ^^PCI0.LPCB.EC0.BTDT)
                    }

                    Method (BTPO, 0, NotSerialized)
                    {
                        ^^PCI0.LPCB.EIOW (One, One, 0xF4, One)
                        ^^PCI0.LPCB.EC0.BTOF ()
                    }

                    Method (BTPF, 0, NotSerialized)
                    {
                        ^^PCI0.LPCB.EIOW (One, One, 0xF4, Zero)
                        ^^PCI0.LPCB.EC0.BTOF ()
                    }

                    Method (BTST, 0, NotSerialized)
                    {
                        Store (^^PCI0.LPCB.EC0.BTSW, Local3)
                        If (Local3)
                        {
                            ShiftLeft (^^PCI0.LPCB.EC0.BTDT, 0x06, Local0)
                            ShiftLeft (^^PCI0.LPCB.EC0.BTPW, 0x07, Local1)
                        }
                        Else
                        {
                            Store (Zero, ^^PCI0.LPCB.EC0.BTDT)
                            Store (Zero, ^^PCI0.LPCB.EC0.BTPW)
                            Store (One, BTPR)
                            Store (Zero, Local0)
                            Store (Zero, Local1)
                        }

                        Or (Local0, Local1, Local2)
                        Or (Local2, Local3, Local2)
                        Return (Local2)
                    }
                }
            }

To:

                Device (BT)
                {
                    Name (_HID, "TOS6205")  // _HID: Hardware ID
            Name (_STA, Zero)  // _STA: Status
            }

No idea if it works, i applied this method to my SSDT only. 

[RCOO]

Tried what you suggested. Built-in bluetooth still is enabled.

[WaldMeister]

Hmm, 

^^PCI0.LPCB.EC0.BTOF ()

Seems to be the method off, perhaps the nvidia method on notebooks can be used. 

No hardware switch present you can use? 

[RCOO]

Nope. No hardware switch.

Where would I insert that statement in the DSDT?

[WaldMeister]

Method _REG should do the trick. 

            Method (_REG, 2, NotSerialized)  // _REG: Region Availability
            {
                If (LEqual (Arg0, 0x03))

                    Store (EIOR (0x07, Zero, 0xA3F4), Local0)
                    And (Local0, Zero, Local0)
                    If (LGreaterEqual (OSYS, 0x07D9))
                    {
                        EIOW (0x07, Zero, 0xA3F4, 0x03)
                    }
                    Else
                    {
                        If (LGreaterEqual (OSYS, 0x07D6))
                        {
                            EIOW (0x07, Zero, 0xA3F4, One)
                            Store (One, OSTY)
                        }
                        Else
                        {
                            If (LEqual (OSYS, 0x03E8))
                            {
                                EIOW (0x07, Zero, 0xA3F4, 0x02)
                            }
                            Else

                                {
                                    If (LNotEqual (OSYS, Zero))
                                    {
                                        EIOW (0x07, Zero, 0xA3F4, Zero)
                                        Store (Zero, OSTY)
                                    }
                                }
                            }
                        }
                    }
                }

                {
                    HTEV (0x02)
                }

                Store (One, ACPW)
                Sleep (0x0A)
                Store (ACPW, PWRS)
                PNOT ()
                BTOF ()
            }

iasl 5.0 returns errors, compiled it under 4.0.

 

Anyway, no idea if it works, worth a try though

Tried that DSDT. Still did not work. Thanks for the attempt though.
