J2ME Bluetooth programming (Episode 2)

Peace upon you,

I apology about delaying but I'm sure you forgive me this delay because you know I'm really so busy. In first episode we got introduction about BT and also knew BT Features.Ok let's dig into more details. In this episode after reading it, you should knew terminology of Bluetooth Network Topology , Bluetooth Communication Types and Java BlueTooth API (JABWT)

Bluetooth Network Topology

When two or more Bluetooth-enabled devices come within range and establish a connection, a personal area network is formed. A personal area network can either be a piconet or a scatternet.

• Piconet: Is a single master and up to seven slaves. No matter what kind Bluetooth devices are involved (whether they are phones, access points, PDAs,laptops, headsets, etc.) The master of the piconet is the one that initiates the connection. The device that accepts the connection automatically becomes the slave. Master/slave roles are not predefined; so if a piconet exists between a laptop and a PDA, either device could be the master or the slave.




• Scatternet: Is a scatternet is essentially a chain of piconets. A scatternet is formed when the slave of a piconet also become the master of its own piconet.
