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:
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.
