The Research And Realization Of Bluetooth Headset Profile

Bluetooth technology is a world wide open standard for wireless data and voicecommunication, it is built upon low cost local area wireless connection with which ashort range wireless channel can be set up between fixed and mobile devices.Bluetooth technology connects portable computers and celluar phones wirelessly.Thisachievement leads to an even closer relationship between computer andcommunication and enables people exchanging data everywhere ang anytime.Bluetooth technology is demanded to apply to the small-scale consumption terminalproducts more and more, the Bluetooth headset that this thesis introduces is a bestillustration.This thesis introduces the characteristics of Bluetooth technology, the structure ofBluetooth core specifications stack and discusses the implementation of protocol indetail. And also this thesis introduces all of the application of Bluetooth profile.After studying and analyzing the theory of Bluetooth audio communication andBluetooth headset profile, this paper expounds the design and implement of Bluetoothheadset application in hardware and software, which is based on CSR's Bluetoothchip and the development kit of CSR.The circuit and code in the paper has been fully debugged and tested in thefactual application. Also, the headset can create a connection and communicate with acelluar telephone which has Bluetooth function in audio channel.
