2-54 Bluetooth PC Card from IBM: Installation and User’s Guide

Discoverability Mode

Discoverability Mode refers to whether other devices can discover your device.
In other words, selecting non-discoverable mode is a way to prevent remote
devices from discovering your device.
The Bonding tab
Bonding refers to the creation of a link key – a bond – between two devices. Bond-
ing is used when a device requires link level security (see “The Security tab” on
page 2-53 for more information). When a remo te de vic e att em pts to co nnec t to th e
device requiring link level security, the users of both devices are prompted for a
password. They must then enter the same password.
The purpose of bonding is for two devices to be able to identify each other so that
no remote device can connect without knowing the right password. This is conve-
nient if, for instance, you do not want any other device than your own Bluetooth-
enabled phone to be able to connect to your computer. Other devices trying to
connect are prompted for the password, which prevents them from interfering
with the current connection.
The duration of the bonding can be set to last beyond the current link; if so, the
two devices are prompted only for the password the first time they connect (i.e.,
when they create the bond).
When creating the bond and when making use of an existing one, both devices
must be in bondable mode. Bonding settings are configured in the Bonding tab of
the Bluetooth Neighborhood Properties window.
In the Bonding tab, you can decide whether your device is able to bond to other
devices. To be able to establish a new bond and to make use of an existing one,
your device must be in bondable mode.

Default Bluetooth Bonding Expiration

In Default Bluetooth Bonding Expiration, you can set bonding to expire when
the link is disconnected, after a specified period of time, or never.
Note: The settings you make in the Bonding tab are default settings that are
applied to all remote devices. For information on how to make settings for
