NAME
     btsco -- Bluetooth SCO Audio

SYNOPSIS
     btsco*    at bthub?
     audio*    at audiobus?

DESCRIPTION
     The btsco driver provides support for Bluetooth SCO Audio devices through the audio(4)
     driver.

     The btsco driver must be configured at run time with the btdevctl(8) program.  The following
     properties are used by the btsco driver during autoconfiguration:

     local-bdaddr
	       Local device address.

     remote-bdaddr
	       Remote device address.

     service-name
	       The btsco driver matches the 'HF' and 'HSET' services.  For the 'HF' service, the
	       btsco device will, on open(2), listen for incoming connections from the remote
	       device.	Otherwise, btsco will attempt to initiate a connection to the remote
	       device.

     rfcomm-channel
	       This integer value is not used directly, but will be stored and passed via the
	       BTSCO_INFO ioctl as below:

     SCO connections require a baseband connection between the two devices before they can be
     created.  The btsco driver does not create this, but can provide information to facilitate
     an application setting up a control channel prior to use, via the BTSCO_INFO ioctl(2) call
     on the mixer device, which returns a btsco_info structure as follows:

     #include <dev/bluetooth/btsco.h>

     struct btsco_info {
	     bdaddr_t	     laddr;	     /* controller bdaddr */
	     bdaddr_t	     raddr;	     /* headset bdaddr */
	     uint8_t	     channel;	     /* RFCOMM channel */
	     int	     vgs;	     /* mixer index speaker */
	     int	     vgm;	     /* mixer index mic */
     };

     #define BTSCO_INFO      _IOR('b', 16, struct btsco_info)

     The btsco driver can be configured to act in Connect or Listen mode.  In Connect mode, the
     btsco driver will initiate a connection to the remote device on an open(2) call, whereas in
     Listen mode, open(2) will block until the remote device initiates the connection.

HISTORY
     The btsco driver was written for NetBSD 4.0 by Iain Hibbert under the sponsorship of
     Itronix, Inc.

BUGS
     btsco takes no notice of the HCI Voice Setting in the Bluetooth controller, and this must be
     0x0060 (the default) as alternate values are currently unsupported.
