3-1 Introduction
Bluetooth™ for Windows (BTW) software installs with a default configuration
that allows the application to be used “out-of-the-box” without making
decisions about security and other user-configurable options.
The default configuration settings include:
x Medium Bluetooth security.
x Service startup at system start.
x Default My Shared Directory and My Inbox.
These settings allow your computer to find the discoverable and connectable Bluetooth-
enabled devices within radio range (referred to as the Bluetooth Neighborhood). Your
computer will then be able to use the services on these devices, for example, surf the
web. In turn, these other Bluetooth devices (referred to as remote devices) will be able to
discover your computer and use its services.
Your computer will also be ready to wirelessly accept items including contacts
(electronic business cards), appointments and meetings, messages received
as e-mail, and notes.
3-1.1 BTTRAY
When BTW is installed on your computer, a shortcut for one of its components—the
Bluetooth System Tray (BTTray)—is added to the Microsoft® Windows® Startup folder.
On system start, it is automatically started and a BTTray icon appears in the Windows
system tray to notify you that it is running. BTTray functionality provides:
x Unobtrusive notification when intervention is required to authorize a security
request or enter a Bluetooth passkey.
x Dialog boxes that prompt for security authorization and allow passkey entry.
x Bluetooth “pairing” support.
x Access to the Bluetooth Configuration window.
The BTW Bluetooth stack is also started on system start. This program runs without user
intervention. The stack is the engine behind the scenes that drives the BTW software and
allows your computer and its Bluetooth device (for example, a USB dongle, a PC card, or
a multi-port) to communicate with other Bluetooth devices. The stack server controls the
Bluetooth device attached to your computer, protects it from unauthorized intrusion, and
ensures that your computer’s Bluetooth connections operate correctly.
BTTray also runs in the background. It waits for notifications from the stack server that a
remote device has requested access to services on your computer. However, notification
is dependent upon how BTW security is configured:
x If High security is set in the General tab of the Bluetooth Configuration window,
BTTray will display a passkey notification each time a non-paired device wants
to discover local services on your computer. The High security setting requires
all remote devices to supply a passkey, like a Personal Identification Number
(PIN), before services can be discovered. All data will be sent using
encrypted links.
x If Medium security is set in the General tab of the Bluetooth Configuration
window, BTTray will display a security dialog only when the specific local
service that the remote device is requesting requires authentication or
authentication and authorization.
