NAME

     bthub -- Bluetooth Remote Device Hub

SYNOPSIS

     bthub* at bcsp?
     bthub* at bt3c?
     bthub* at btbc?
     bthub* at btuart?
     bthub* at sbt?
     bthub* at ubt?

     bthidev* at bthub?
     btmagic* at bthub?
     btsco* at bthub?

DESCRIPTION

     The bthub device is used to attach remote Bluetooth devices to the system, and will attach to Bluetooth controllers as they are enabled.

CONFIGURATION

     Normally, Bluetooth Remote Devices will be configured on the bthub using the btdevctl(8) program, which passes a proplib(3) dictionary to the
     control file /dev/bthub with the BTDEV_ATTACH and BTDEV_DETACH ioctl(2) commands.

     The following properties are used by bthub:

     local-bdaddr  Local BD_ADDR.  This required property should be a six byte data blob.

     remote-bdaddr
		   Remote BD_ADDR.  This required property should be a six byte data blob.

     service-name  Service name.  This required property should be a string indicating the service to configure, and may be one of the following:

		   HF		 Handsfree, see btsco(4).
		   HID		 Human Interface Device, see bthidev(4).
		   HSET 	 Headset, see btsco(4).

     Properties used by the configured device are listed in the appropriate device manual page.

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 incom-
	       ing 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.
