Bluetooth Connection
Bluetooth
functions are in the model of Client/Server. One
Bluetooth
device provides services, and another
Bluetooth
device uses these
Bluetooth
services. After
connection, a
Bluetooth
link is set up between two devices, and the link is called a
Bluetooth
connection. Users can disconnect the connection after finishing his job on
Bluetooth
.
Bluetooth Connection Shortcut
Connection shortcut is used for saving time in searching
devices and browsing services. After a connection is established, it can be saved as a shortcut. The
shortcut can be used later to re-establish the connection, without searching the remote
Bluetooth
devices and browsing services. After a connection is setup, the connection can be saved as a
shortcut, which can be used later without searching
Bluetooth
devices or browsing services.
Bluetooth Device
Bluetooth
devices are addressed in two ways: (1) When referring to the local
device configuration, a
Bluetooth
Device is the local
Bluetooth
hardware which can be a USB
dongles, a UART device, a PCMCIA card or a BCSP device. The user is expected to select the
interface of his
Bluetooth
device in his configuration. (2) When referring to the
Bluetooth
application, it is the
Bluetooth
system as a whole, e.g. a
Bluetooth
modem,
Bluetooth
mobiles or a
Bluetooth
PDA etc. My PC together with the BlueSoleil and the
Bluetooth
dongle would also be
addressed as a remote
Bluetooth
device by other
Bluetooth
devices.
Bluetooth Device Address
A unique 48-bit address that distinguishes between different
Bluetooth
transceivers. Every
Bluetooth
device has a unique address so that other devices can find it
and communicate with it. The address appears in the form of 00:03:20:00:0D:0A.
Bluetooth Device Class
According to the
Bluetooth
standard, every
Bluetooth
device is assigned
a device type, which is represented in device class. The
Bluetooth
device class is three bytes in
length in the form of 04:01:00. On the computer side, the class may be Server, Desktop or Laptop.
Users will be asked to select it during the first time starting.
Bluetooth Device Inquiry
To use
Bluetooth
, the user has to find the remote device first. The
searching procedure is called device inquiry. There are two kinds of inquiry procedure, named
General Inquiry and Limited Inquiry. General Inquiry will find all the
Bluetooth
devices in general
discoverable mode and limited discoverable mode. Limited Inquiry will find only the devices in
limited discoverable mode.
Bluetooth Dongle
A
Bluetooth
device which can be added onto a PC or a notebook to make it
Bluetooth
enabled. Typically a USB device.
Bluetooth bonding
A user initiates the bonding procedure and enters a passkey to create a paired
relationship between two devices. This differs from the authentication procedure where the user is
requested to enter a passkey during the establishment of a link.
Bluetooth Passkey
In the
Bluetooth
authentication procedure, a
Bluetooth
passkey is requested
on both connection sides. The same
Bluetooth
passkey should be input on both sides. If the passkeys
are the same, the authentication procedure is successful and connections can be setup. If the
passkeys are different, the connection and authentication will fail.
Bluetooth Peripheral Device
This is the implementation of the
Bluetooth
Human Interface
Device profile (HID). By using HID, a
Bluetooth
peripheral input device such as
Bluetooth
mouse
or keyboard can interface with the host PC remotely.
Bluetooth Security
Bluetooth
security is an important part for the wireless communication
technology. Illegal access to your computer can be rejected. There are three levels of security: Low,
Medium and High. In Low level, there is no security check. In Medium level, remote
Bluetooth
devices can browse your services. Security is set on every service. The service can be set to request
or not request for authentication and authorization. If you request for authentication, the remote
