BTHSET(1)               NetBSD 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.
