BTHSET(1) BSD General Commands Manual BTHSET(1)
bthset -- Bluetooth Headset utility
bthset [-v] [-c command] [-m mixer] [-p file] [-s channel]
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 control 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 opening the control con-
nection, bthset will listen on the channel for incoming connections from the Headset and
register as Headset Audio Gateway with the local SDP server.
The options are as follows:
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 environ-
ment variable, if set.
-h Print usage message.
Specify the path to the mixer device. This defaults to the contents of the
BTHSET_MIXER environment variable, or /dev/mixer if not set.
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.
Register with the local SDP server as a Headset Audio Gateway and listen for connec-
tions on the given RFCOMM server channel.
-v Be verbose.
The bthset utility exits 0 on success, and >0 if an error occurs.
