NAME

btconfig — configure bluetooth devices

SYNOPSIS

btconfig

[-svz] [device [parameters]]

btconfig

[-l]

DESCRIPTION

btconfig is used to configure Bluetooth devices. If the device is given, but no parameters, then btconfig will print information about the device. If no device is given, a basic list of devices will be printed.

When the -l flag is used, just the device names will be printed.

COMMANDS

The following parameters may be specified with btconfig:

up

Enable Bluetooth Device.

down

Disable Bluetooth Device.

pscan

Enable Page Scan. This enables incoming connections to the device.

-pscan

Disable Page Scan.

iscan

Enable Inquiry Scan. This puts the device in Discoverable mode.

-iscan

Disable Inquiry Scan.

encrypt

Enable encryption. This will cause the device to request encryption on all baseband connections, and will only work if authentication is also enabled.

-encrypt

Disable encryption.

auth

Enable authentication. This will cause the device to request authentication for all baseband connections.

-auth

Disable authentication.

switch

Enable Role Switching. In a Bluetooth piconet there is one Master and up to seven Slaves, and normally the device that initiates a connection will take the Master role. Enabling this option allows remote devices to switch connection roles.

-switch

Disable Role Switching.

master

Request the Master role when accepting connections.

-master

Do not request Master role.

hold

Enable Hold Mode.

-hold

Disable Hold Mode.

sniff

Enable Sniff Mode.

-sniff

Disable Sniff Mode.

park

Enable Park Mode.

-park

Disable Park Mode.

name name

Set human readable name of device.

ptype type

Set packet types. type is a 16 bit hex value specifying packet types that will be requested by outgoing ACL connections. By default, all packet types that the device supports are enabled, see bluetooth specifications for more information if you want to change this.

class class

Set class of device. class is a 6 digit hex value the value of which declares the device capabilities. See the “Assigned Numbers - Baseband” document at http://www.bluetooth.com/ for details of constructing a Class of Device value. As a starter, 0x020104 means Desktop Computer, with Networking available.

fixed

Set fixed pin type.

variable

Set variable pin type.

inquiry

Perform device Discovery from the specified device and print details.

imode type

Set inquiry mode type to control which event formats are generated during a device inquiry. The type can be:

std

Standard Inquiry Result Event format.

rssi

Enable Remote Signal Strength Indicator (RSSI) in inquiry results. This will only work if the device features indicate <RSSI with inquiry result>.

ext

Inquiry Result with RSSI format or Extended Inquiry Result fomat. This will only work where the device features indicate <extended inquiry>, and the Extended Inquiry Result will only occur when the remote device provides the extended information.

reset

Perform a hard reset on the device and re-initialise system state.

voice

Set Voice Setting. [This should be 0x0060 for now]

pto

Set Page Timeout value. This is a decimal value in milliseconds, indicating how long the device will attempt to page another device when opening baseband connections.

scomtu

Change SCO mtu value. This is a decimal value, see ubt(4) for reasons why you may need to do this.

All parameters are parsed before any device operations take place. Each time the -v flag is given, verbosity levels will be increased.

Super-user privileges are required to change device configurations.

DIAGNOSTICS

Messages indicating the specified device does not exist, the requested address is unknown, or the user is not privileged and tried to alter an device's configuration.

BUGS

The output is very messy.
