| With the rapid development of wireless communication technology and mobile communication technology, people find it more and more necessary to make mobile devices, such as Mobile phone, Hand PC and PDA, interconnected wirelessly, which brings forth Bluetooth technology. Bluetooth is a kind of short-range wireless communication, a world widely open standard for wireless data and voice communication, which can set up an adhoc LAN between fixed devices and mobile devices with low cost, short-range wireless connection. Bluetooth technology makes portable devices connected and enables people to exchange information anytime and anywhere. And Bluetooth will bring a promising market.The protocol specification of Bluetooth communication designed by Special In terest Group is a kind of global uniformed technical standard. It must be conformed when Bluetooth-related products are designed. Under the Bluetooth specification framework, the paper introduces the architecture and profiles of Bluetooth. By conforming embedded system, Bluetooth software module, the paper analyzes Bluetooth software module under embedded system and the development of Bluetooth in embedded system.Audio and video distribution has a wide application foreground. AVDTP, A2DP, GAVDP, VDP protocol and profiles ard drafted out by SIG(Bluetooth Special Interest Group). These protocol and profiles provide the interoperable between different devices. The paper introduces Bluetooth audio module, which includes Bluetooth Headset Profile and Bluetooth Advanced Audio Distribution Profile, and the structure of Headset profile and A2DP.The paper explains the design of Headset profile and A2DP, then put forwards the solutions of Headset profile and A2DP based on Windows CE. |
