BTHSET(1)		  BSD General Commands Manual		     BTHSET(1)

NAME
     bthset — Bluetooth Headset utility

SYNOPSIS
     bthset [-v] [-c command] [-m mixer] [-p file] [-s channel]
     bthset [-h]

DESCRIPTION
     The bthset utility is used to access a Bluetooth Headset with the
     btsco(4) audio device.  It opens the mixer(4) device and creates the con‐
     trol connection to the headset, then conducts volume settings each way.
     When bthset receives a SIGUSR1 signal, it will start sending RING codes
     to the headset until the headset button is pressed or a SIGUSR2 signal is
     received.	If the headset is ringing and bthset receives a button press
     notification, the specified command (if any) is executed.

     When the server channel is specified with the -s option, instead of open‐
     ing the control connection, bthset will listen on the channel for incom‐
     ing connections from the Headset and register as Headset Audio Gateway
     with the local SDP server.

     The options are as follows:

     -c command
	     Specify an optional command to be executed when the headset
	     responds to ringing with a button press event.  This defaults to
	     the contents of the BTHSET_COMMAND environment variable, if set.

     -h	     Print usage message.

     -m mixer
	     Specify the path to the mixer device.  This defaults to the con‐
	     tents of the BTHSET_MIXER environment variable, or /dev/mixer if
	     not set.

     -p file
	     Write the PID to file so that other programs can find us later.
	     This defaults to the contents of the BTHSET_PIDFILE environment
	     variable, if set.

     -s channel
	     Register with the local SDP server as a Headset Audio Gateway and
	     listen for connections on the given RFCOMM server channel.

     -v	     Be verbose.

EXIT STATUS
     The bthset utility exits 0 on success, and >0 if an error occurs.

FILES
     /dev/mixer
