Routing Audio to the Bluetooth Hardware (Windows Embedded CE 6.0)
1/6/2010
The AG service provides the functionality for routing audio to the Bluetooth chip. This is done by sending the message, WODM_BT_SCO_AUDIO_CONTROL that the audio driver receives to route audio.
Note
The Audio Gateway service automatically creates a SCO connection to the headset device.
Windows Embedded CE provides a sample audio driver, Btscosnd that processes this message in the WAV_IOControl function to provide audio routing. WODM_BT_SCO_AUDIO_CONTROL offsets the need for the hardware platform to provide this functionality.
For more information about Btscosnd, see Protocol Extension Sample.
