Protocols stack & connection establishment in Bluetooth radio

Some of the issues to be considered in the design of the higher layers of its protocol stack are those that allow the Bluetooth module to be easily integrated into any existing device that may benefit from being connected. Further, for rapid acceptance into the market, it should be possible for existing applications developed over conventional protocols to be easily portable to the Bluetooth platform. In addition, other wireless initiatives, such as IrDa, 2WAP and HomeRF, should also be able to interoperate with this standard. With this in view, interface points where existing protocols may be used over the Bluetooth platform are provided. A Bluetooth device has some peculiar needs not covered by existing protocols, like the need to discover all the services that are available on devices in its proximity. An attempt has been made to provide for interoperability and universal acceptance. Existing protocols can be supported over Bluetooth for rapid development of applications. We provide a protocol stack that takes into account all these problems.
