Connectio
n
The term “Bluetooth” refers to a worldwide standard for th
e
wireless exchange of data between two devices. In order to ex
-
change 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. Every Bluetooth device that provides a
service must be prepared to respond to a connection
request.
Bluetooth soft- ware is always running in the background on
the
server, ready to respond to connection requests.
