About Client and Server
Before we start discussing about what each of the services does, let us briefly tell you a bit about
Client and Server since we will be mentioning a lot of these two in this chapter.
In order for two Bluetooth devices to exchange data, they must establish a connection. However,
before a connection is established, one device must request a connection with the other. This is
the Client.
The second device that accepts or rejects the connection is then known as the Server. Many
Bluetooth devices can act as both client and server.
Bluetooth Serial Port
The Bluetooth Serial Port service allows two Bluetooth devices to establish a wireless connection
through a virtual communications port and then use that connection as if it were a hardwired
serial cable between those devices.
Connection is initiated from the client. To establish a Bluetooth serial port connection:
1. On
the
Client
, open
My Bluetooth Places
by double-clicking the
icon on your desktop.
2. Select
Entire Bluetooth Neighborhood
.
3. Right-click anywhere except on a device name and select
Refresh
from the pop-up menu. This updates your current list of
available devices.
4. Right-click the server (the receiver of your request) with which
you want to establish a connection. Select
Discover Available
Services
from the pop-up menu to display an updated list of
available services.
5. Double-click
Bluetooth Serial Port
. A dialog box appears,
containing the communications port number assigned to this
connection by the client. The application that will use this
connection must be configured to send data to this port.
Depending on the security configuration, the dialog box that provides communications port
information may not appear until after Authentication and Authorization have been accomplished.
The application on the server must be configured to use the correct communications port.
