Introduction
INTRODUCTION TO BLUETOOTH
The term “Bluetooth” refers to a worldwide standard for the wireless exchange of data
between two devices.
In order to exchange data, two Bluetooth devices must establish a connection.
Before a connection is established, one device must request a connection with another.
The second device accepts (or rejects) the connection.
The originator of the request is known as the client.
The device that accepts (or rejects) the request is known as the server.
Many Bluetooth devices can act as both client and server.
A client Bluetooth device runs a software program that requests a connection to another
device as part of its normal operation. For example, the program may request a
connection to a remote computer, a printer, or a modem.
Becoming a Bluetooth client normally requires an action by the device operator, such as
an attempt to browse a remote computer, print a file, or dial out on a modem.
Every Bluetooth device that provides a service must be prepared to respond to a connection
request. Bluetooth software is always running in the background on the server, ready to
respond to connection requests.
