.Sh NAME
|
|
.Nm bluetooth.device.conf
|
|
.Nd Bluetooth device configuration file
|
|
.Sh DESCRIPTION
|
|
Bluetooth device configuration framework provides ability to adjust certain
|
|
Bluetooth device parameters on per-device basis.
|
|
.Pp
|
|
Bluetooth device configuration files are plain text files that should conform
|
|
to basic
|
|
.Xr sh 1
|
|
syntax.
|
|
Even though Bluetooth device are not exactly shell scripts,
|
|
they are parsed and passed through shell
|
|
.Ic eval
|
|
command.
|
|
This makes it possible to use various shell tricks in the Bluetooth device
|
|
configuration files.
|
|
.Pp
|
|
The
|
|
.Pa /etc/rc.d/bluetooth
|
|
script is used to start and stop Bluetooth devices.
|
|
This script is not executed by default when system boots.
|
|
It is called by
|
|
.Xr devd 8
|
|
in response to Bluetooth device arrival and departure events.
|
|
It is possible to execute this script by hand if required.
|
|
The script accepts Bluetooth device driver name as an extra parameter.
|
|
.Pp
|
|
The system wide Bluetooth device configuration file is called
|
|
.Pa /etc/defaults/bluetooth.device.conf .
|
|
Configuration parameters set in the system wide Bluetooth device configuration
|
|
file apply to every Bluetooth device connected to the system.
|
|
.Pp
|
|
Configuration parameters overrides for the specific Bluetooth device
|
|
should be placed in the
|
|
.Pa /etc/bluetooth/ Ns Ar DEVICE_DRIVER_NAME Ns Pa .conf
|
|
file.
|
|
Where
|
|
.Ar DEVICE_DRIVER_NAME
|
|
is the device driver name of the Bluetooth device.
|
|
.Pp
|
|
The following list provides a name and short description for each
|
|
variable that can be set in a Bluetooth device configuration file.
|
|
.Bl -tag -width indent-two
|
|
.It Va authentication_enable
|
|
.Pq Vt bool
|
|
The
|
|
.Va authentication_enable
|
|
parameter controls if the device requires to authenticate the remote device
|
|
at connection setup.
|
|
If set to
|
|
.Dq Li YES ,
|
|
the device will try to authenticate the other device at connection setup.
|
|
Bluetooth authentication requests are handled by
|
|
.Xr hcsecd 8
|
|
daemon.
|
|
.It Va class
|
|
.Pq Vt str
|
|
The
|
|
.Va class
|
|
parameter is used to indicate the capabilities of the device to
|
|
other devices.
|
|
For more details see
|
|
.Pa https://www.bluetooth.org/foundry/assignnumb/document/baseband .
|
|
.It Va connectable
|
|
.Pq Vt bool
|
|
The
|
|
.Va connectable
|
|
parameter controls whether or not the device should periodically scan for
|
|
page attempts from other devices.
|
|
If set to
|
|
.Dq Li YES ,
|
|
the device will periodically scan for page attempts from other devices.
|
|
.It Va discoverable
|
|
.Pq Vt bool
|
|
The
|
|
.Va discoverable
|
|
parameter controls whether or not the device should periodically scan for
|
|
inquiry requests from other devices.
|
|
If set to
|
|
.Dq Li YES ,
|
|
the device will periodically scan for inquiry requests from other devices.
|
|
.It Va encryption_mode
|
|
.Pq Vt str
|
|
The
|
|
.Va encryption_mode
|
|
parameter controls if the device requires encryption to the remote device
|
|
at connection setup.
|
|
At connection setup, only the devices with the
|
|
.Va authentication_enable
|
|
parameter enabled and
|
|
.Va encryption_mode
|
|
parameter enabled will try to encrypt the connection to the other device.
|
|
Possible values are
|
|
.Dq Li NONE
|
|
encryption disabled,
|
|
.Dq Li P2P
|
|
encryption for only point-to-point packets,
|
|
or
|
|
.Dq Li ALL
|
|
encryption for both point-to-point and broadcast packets.
|
|
.It Va hci_debug_level
|
|
.Pq Vt int
|
|
HCI node debug level.
|
|
Higher values mean more verbose output.
|
|
.It Va l2cap_debug_level
|
|
.Pq Vt int
|
|
L2CAP node debug level.
|
|
Higher values mean more verbose output.
|
|
.It Va local_name
|
|
.Pq Vt str
|
|
The
|
|
.Va local_name
|
|
parameter provides the ability to modify the user friendly name for the device.
|
|
.It Va role_switch
|
|
.Pq Vt bool
|
|
The
|
|
.Va role_switch
|
|
parameter controls whether the local device should perform role switch.
|
|
By default, if role switch is supported, the local device will try to perform
|
|
role switch and become Master on incoming connection.
|
|
Some devices do not support role switch and thus incoming connections from
|
|
such devices will fail.
|
|
If
|
|
.Va role switch
|
|
is disabled then accepting device will remain Slave.
