摘要
采用蓝牙技术与分组语音技术相结合的方法,设计蓝牙接入网关并利用LwIP协议栈在Blackfin处理器上开发嵌入式系统,通过以太网建立起蓝牙语音网络。系统地介绍了蓝牙语音网的系统架构以及接入点的软硬件设计方法。实际测试结果表明本系统可以同时支持7路蓝牙语音传输并实现蓝牙耳机在不同接入点之间的切换,测试效果满足实时通话要求。
In the paper, combining bluetooth technology and packet voice technology, we design bluetooth access gateway and develop embedded system on Blackfin processor with lightweight TCP/IP stack to establish a bluetooth voice network via ethernet. The paper introduces the system architecture of voice network over bluetooth and hardware and software design methods of accessing point. The actual test results show that the system allows up to 7 bluetooth terminals to transmit their audio signals simultaneously to each destination through ethernet and achieve switch for bluetooth headsets among different access points. Test results achieve the requirements of real-time voice communication.
