I work with HSP, HFP profiles in android and use for development pandaboard.
So which drivers used for SCO (as pcm packets) data tranmission in TI board?
I think for this used some implementation of AudioHardware for AudioFlinger and some driver (may be several for audio and bluetooth). I can't understand because btwilink driver usb UART_HCI bus and doesn't participates in SCO data transmissions and may be this driver provided without source.
