Research And Realization On The Bluetooth LAN Gateway

With the development of Bluetooth technology and importance of Internet to pepple, more and more Bluetooth equipments appear around people. Just through analysing to current situation of the development of Bluetooth technology, the research of the Bluetooth LAN gateway is carried on.Based on Bluetooth Core Package 1.0, 1.1 and 1.2, Bluetooth technology and agreement has been analysed in detail and some new content on Bluetooth Core Specification Version 2.0 + Enhanced Data Rate in this paper is added at first. Then make a narration to design idea of Bluetooth LAN gateway, and through comparing to three kinds of development scheme of Bluetooth, after then show the development scheme of the Bluetooth LAN gateway: the Bluetooth module and the development scheme based on BlueZ agreement stack have been confirmed. Afterwards make a briefly narration to develop board of Bluetooth and S3C44BOX ARM develop board that be used in the course of development. In the most important "The Design and Realization of Bluetooth System" chapter, make out hardware design to Bluetooth LAN gateway at first, then narrate in detail the transplantation of uClinux operating system and BlueZ Bluetooth protocol stack, after that make analysis to BlueZ Bluetooth protocol stack, finally come true PAN profile by analysing the course of forming network on PAN and the process of communications between NAPU and NAP in detail. At the end of this paper, make a test to Bluetooth LAN gateway by setting up the Bluetooth LAN.
