| Bluetooth technology i$ opening standard in the field of wireless data and digital audio communication. It can set up a wireless communication environment for fixed or mobile devices with low-cost short range wireless connection. Currently, with the development of information industry and the growing demand for wireless operation, Bluetooth technology is applied not only in office environment but in lots of information system with realizing some special functions.Combined with Bluetooth application practical project, this thesis designed a bluetooth profile oriented data adapter module for the purpose of reducing the complication in secondary development.Differ from the traditional HCI Bluetooth data module, this module has a relative simple user interface and face to data services. It can be applied in other information system easily. Bluetooth core stack and general profiles was embedded into the module, that reduced the difficulties of developing bluetooth application system.Based on the intensive research in bluetooth protocol system, this thesis give some solutions about the techniques of realizing bLuetooth protocol stack. As a result, we design and realize the multi-profile supported bluetooth data adapter module depending on the embedded system developing techniques and the techniques of realizing protocol. The research results below has been gotten:1. Bring solutions for key taches in realizing bluetooth protocol.2. Design a portable and easy-upgraded embedded software system structure.3. Define a new command language, called BT language, for module application, realize the command syntax parser as well.4. Design and realize the state machine for the module software system running.5. Realize most of the basic function about the bluetooth protocol, also we optimize some functions for bring convenience when operating the data module. Especially, the function of parameter auto recorded and auto registered makes the module more smart.
