Research And Implementation Of Bluetooth Personal Area Network

The Bluetooth technology is a combine product of mobile communication and computer network technology, its appearance has provided a kind of open wireless pronunciation and data communication standard. Along with widespread application of the short distance wireless correspondence is more and more used in the modern society, the wireless Personal Area Network (PAN) becomes one of the most rapid developing domains currently. By costing inexpensive, the network is nimble and so on merit, the Bluetooth becomes the new research hot spot of the multitudinous wireless technology and the good choice of PAN realization.The key problem this article intends to solve is that in the foundation of research and analysis to the Bluetooth technology and the wireless PAN, design and realizes a kind of Bluetooth PAN using the module technology.Firstly, this article studied the Bluetooth technology characteristic and application profile of PAN, analyzed the Bluetooth Network Encapsulation Protocol (BNEP). Secondly, unified the design principle of COM module technology and BNEP protocol, Bluetooth PAN was designed, which based on the module technology, including the bottom upward top system structure, driver structure design as well as data transmission mechanism design and so on. Thirdly, this article realized Bluetooth PAN in Windows OS platform, including the first floor correspondence mechanism realization, the service management realization and the connection management realization, etc. Then according to project reality, several typical questions have been analyzed and corresponding solution has been produced.Through analysis and research of Bluetooth test principle, this article designed and realized the Bluetooth PAN automated test system. According to the practical application of this automated test system application, the performance and stability of Bluetooth PAN is confirmed. At the same time, PAN automated test has provided the reference for automated test of other Bluetooth profile model.As a part of Bluetooth software BlueSoleil 5.x, Bluetooth PAN which designed and realized by this article has already entered the domestic and foreign markets, obtained user's approval, and achieved the anticipated goal.
