Bluetooth system being application in family gateway have dissertated in the theme. The theme follows by the clue of discussing the system scheme with rules of integer design, which stands out the fluent feature of process of design. In both sides of theory and realization, the theme not only introduces the basic principle and implement, but embodies the thinking in project. Firstly the feasibility of building community LAN have demonstrated; Secondly stream model of internal network determined in nature, at the same time the selected hardware project are analyzed. What's mentioned above will be the base of the succedent discussion. Thirdly, Bluetooth protocol^ cooperation of Bluetooth and coldfire chip> and primitive language have asserted in detail. Finally, material implementation of software and hardware even maul function which system needed are interpreted. Implementing wireless delivering picture with bluetooth system is a concrete sample. The whole theme carries out keeping the consist in content, taking thinking in focus. I wish the theme can be to advantage hi the latter development.
