The Research And Development Of Universal Bluetooth Module

The appearance of Bluetooth is the inevitable final results of the user's needs and technical development of communication. It has already become one of the most expectant technologies in wireless personal area network. Like the personal digital assistant and locomotive telephone, the Bluetooth products are used for satisfying the demands for the moving nature of people too. Compared with them, the Bluetooth products have epoch-making meanings.The market potential of Bluetooth is enormous, whether grasps Bluetooth technology frequently and makes it industrialized or not will influence the developments of information industries of our country to a great extent. The purpose to write this paper is hope to help the person that is about to engaged in and research the Bluetooth products exploitation to be familiar with the Bluetooth environment and grasp Bluetooth technology as soon as possible.This paper is based on Bluetooth criterion 1.1 edition, has been analyzed the communication principle and network structure of Bluetooth technology deeply, researched the scheme of how to develop Bluetooth products, developed the universal Bluetooth module based on Bluetooth host controller interface and existing Bluetooth chips by products, offered the software and hardware solutions of develop Bluetooth application products based on the module for researcher and developer. To prove the feasibility of this scheme, we develop Bluetooth wireless communication test system based on personal computer. We give the detailed description of the whole development course of the Bluetooth product in the paper, which played a active guide role for the development of expansion application products basedon the universal Bluetooth module. At present, the universal bluetooth module products have already getting certain application on the market and bring favorable reflects.At last, this paper summarizes the work in the past of subject, and proposes the research plan for next step.
