bluetooth.device.conf
- Bluetooth device configuration file
DESCRIPTION
Bluetooth device configuration framework provides ability to adjust certain
Bluetooth device parameters on per-device basis.
Bluetooth device configuration files are plain text files that should conform
to basic
sh(1)
syntax.
Even though Bluetooth device are not exactly shell scripts,
they are parsed and passed through shell
eval
command.
This makes it possible to use various shell tricks in the Bluetooth device
configuration files.
The
/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
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.
The system wide Bluetooth device configuration file is called
/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.
Configuration parameters overrides for the specific Bluetooth device
should be placed in the
/etc/bluetooth/ DEVICE_DRIVER_NAME .conf
file.
Where
DEVICE_DRIVER_NAME
is the device driver name of the Bluetooth device.
The following list provides a name and short description for each
variable that can be set in a Bluetooth device configuration file.
authentication_enable
(Vt bool
)
The
authentication_enable
parameter controls if the device requires to authenticate the remote device
at connection setup.
If set to
``YES
''
the device will try to authenticate the other device at connection setup.
Bluetooth authentication requests are handled by
hcsecd(8)
daemon.
class
(Vt str
)
The
class
parameter is used to indicate the capabilities of the device to
other devices.
For more details see
``Assigned Numbers - Bluetooth Baseband''
document.
connectable
(Vt bool
)
The
connectable
parameter controls whether or not the device should periodically scan for
page attempts from other devices.
If set to
``YES
''
the device will periodically scan for page attempts from other devices.
discoverable
(Vt bool
)
The
discoverable
parameter controls whether or not the device should periodically scan for
inquiry requests from other devices.
If set to
``YES
''
the device will periodically scan for inquiry requests from other devices.
encryption_mode
(Vt str
)
The
encryption_mode
parameter controls if the device requires encryption to the remote device
at connection setup.
At connection setup, only the devices with the
authentication_enable
parameter enabled and
encryption_mode
parameter enabled will try to encrypt the connection to the other device.
Possible values are
``NONE
''
encryption disabled,
``P2P
''
encryption for only point-to-point packets,
or
``ALL
''
encryption for both point-to-point and broadcast packets.
hci_debug_level
(Vt int
)
HCI node debug level.
Higher values mean more verbose output.
l2cap_debug_level
(Vt int
)
L2CAP node debug level.
Higher values mean more verbose output.
local_name
(Vt str
)
The
local_name
parameter provides the ability to modify the user friendly name for the device.
role_switch
(Vt bool
)
The
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
role switch
is disabled then accepting device will remain Slave.
FILES
/etc/defaults/bluetooth.device.conf
/etc/rc.d/bluetooth
EXAMPLES
The
/etc/bluetooth/ubt0.conf
file should be used to specify configuration parameters overrides for the
first USB Bluetooth device
(device driver name is
ubt0 )
The
/etc/bluetooth/ubt1.conf
file should be used to specify configuration parameters overrides for the
second USB Bluetooth device.
