| Bluetooth technology is a specification for short-range wireless communication. It has many advantages such as strong anti-interference capability, low cost, low power consumption, good mobility, and particularly have superior performance on voice transmission on phone calls. In order to achieve greater market share, domestic and international mobile phone platforms such as MTK, Spreadtrum, Symbian, Windows Mobile and Linux, have Bluetooth voice technology applied currently, and have been designing Bluetooth-voice-enabled products. In recent years, there have been many emerging mobile phone platforms in domestic. Anyka is one of these platforms whose development is relatively good and rapid, and now it's mainly for the domestic mobile phone market. The Anyka platform yet did not have the function of Bluetooth voice before the research of this paper. Therefore, to integrate and realize this function on the platform has certain degree of difficulty, reflected in the problems of designing solution and software.In order to solve the two problems, this paper relatively designed Bluetooth integration solution and software based on Bluetooth technology and on the Anyka platform, which ultimately brought about a new Bluetooth voice system. The main work of this paper could be divided into two parts: design of integration solution and design of Bluetooth software.For the design of integration solution, this paper took overall consideration of the cost, the difficulty in technique, the stability and other important factors, designed a new structure of Bluetooth voice system, and made further research, obtaining a solution called "single-chip embedded solution". This solution featured fully functional and effective control of integration costs.For the design of Bluetooth software, this paper developed the software closely integrated with the Anyka system, via optimized designing. This software contained several new highlights which could effectively optimize the operation of the software, reduce the burden on the system and guarantee the quality of software. These highlights included Bluetooth process of voice link control and application, mechanism of handling Bluetooth events and AT commands.The experimental results showed that, the new designed Bluetooth voice system based on Anyka had good performance and better compatibility to many Bluetooth headsets. And more, it had similar effects of call quality and distance compared to other mobile phone platforms. Therefore, applying the work mentioned above in this paper, to design and realize the new Bluetooth system can successfully clear the problems of integration solution and software designing. |
