Building a personal area network
[PAN]
You can use the PAN profile to build a network of Bluetooth TM wireless technology-enabled devices.
→ Operating as a server
→ Operating as a client
A personal area network comprises a client-server architecture. The device to which other devices connect is called the "server", and a device that
connects to the server is called a "client."
The client-server relationship is not necessarily a fixed one. The first of two devices to establish a connection can be the server when one other
device is present, and can be the client in other instances.
Note
 The maximum total number of devices that can be used to constitute a single personal area network is seven: one server and six clients.
A network comprising as many as seven devices could theoretically be built, but an operating environment that involves the use of other
Bluetooth
TM wireless technology devices, leaving aside other complications, might require the network to comprise fewer components..
By using the PAN profile, you will be able to build a network that uses the same TCP/IP protocol used in regular LANs. Accordingly, the machine
designated as the server can be used for configuration tasks that utilize DHCP, such as assigning IP addresses to clients.
In addition, you will be able to configure folder and file sharing, which will allow data to be browsed by other servers or clients on the network.
