Research And Application Of The Protocol Stack Of Bluetooth

The study to research how to develop product by analysis the Bluetooth profile and protocal stack. The hardest part of this study is how to choice the right resource and profile to research,and meet the demand.Bluetooth wireless technology is a short-range communications systemintended to replace the cable(s) connecting portable and/or fixed electronicdevices. The key features of Bluetooth wireless technology are robustness, lowpower, and low cost.Many features of the core specification are optional,allowing product differentiation.The Bluetooth core system consists of an RF transceiver, baseband, and protocol stack. The system offers services that enable the connection of devices and the exchange of a variety of classes of data between these devices.With the recent advance in wireless technologies, short-range wireless transmission gradually becomes a new trend, and provides users with more convenient services. One renowned example will be the standardization of Bluetooth specification that provides previously standalone devices the network services. In Bluetooth wireless systems, Bluetooth devices are organized in piconets. A set of piconets can be grouped and interconnected as a scatternet[5].The basic principle and technical features of Bluetooth Technique and protocal stack are introduced and its application area is discussed.The problem in the face of Bluetoothe Technique are also introduced in this paper.This paper briefly introduces Bluetooth SIG and Bluetooth standard progress.The application profiles and practical applications based on Bluetooth technology are given.
