OMAP4460 Bluetooth Audio issus

Other Parts Discussed in Thread: 4460

HI I am using  the http://omapedia.org/wiki/4AI.1.7_OMAP4_Icecream_Sandwich_Panda_Notes for my 4460 pandaboard.

According to http://e2e.ti.com/support/omap/f/849/t/226568.aspx, If I want to  hear the music  through the BT

I should :

1) Use the DVI port if you are using a Pandaboard

2) Pair your BT headset or device

3) Go to the BluetoothSCOA application and check the option to enable music via media player

4) Open media player and start the playback.

 

But could I use the Advanced Audio Distribution Profile (A2DP) instand of the Hands-Free Profile ?

Because the sound of that is very bad and I want to use the HCI_TX & HCI_RX to send the sond.

Also it seem very strange to go to the BluetoothSCOA application and check the option to enable music via media player.

 

Thanks

    Hi Sunny,

    The use of BluetoothSCOA is just to let android know that now the audio have to go to the Bluetooth port instead of the speakers or the headset, and set the path.

    It's very glad to see you again..

    I know that the BluetoothSCOA is let android know that now the audio have to go to the Bluetooth port .

    But there are two preoblems:

    1.  I have paired my BT headset . why it can't tell the android to let the audio go to the Bluetooth port ?  As normal,  it will let the audio of android go to the a2dp.

    2. When I use the BluetoothSCOA. it will send the audio to the Bluetooth port . But it uses the pcm (Hands-Free Profile  right ?) ,the sound of that is very bad .

    Can it use the HCI_TX & HCI_RX  port ?(Hands-Free Profile right ?)

    I modify the device.mk, add the audio.a2dp.default lib

    # BlueZ a2dp Audio HAL module
    PRODUCT_PACKAGES += audio.a2dp.default

    and i see the log:

    Hi Sunny,

    That is because the audio manager for panda is very basic, it is not able to handle several streams and only supports that profile for BT. It is up to the community to make it more complex and support even more profiles. You may want to ask to the panda mailing list how to do that.
