In Bluetooth Connection
The term “Bluetooth” refers to a worldwide standard for the
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.
