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.
