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 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 connection,
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:
- -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 contents 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.
