1、摘要智能住宅伴随着计算机、通信、网络和控制技术的发展而出现，家庭网关作为智能住宅的核心设施把由信息家电、功能各异的传感器、PC及其外设等构成的家庭内部网络和小区局域网联系起来，进而接入国际互联网，实现信息共享、远程控制、集中管理等功能。随着新技术的出现，家庭网关的设计也被注入了新的活力，本文介绍的就是一种融合蓝牙技术的嵌入式家庭网关。蓝牙技术是一种用于各种固定与移动的数字化硬件设备之间的低成本、近距离的无线通讯连接技术，在家庭场合应用可以取代烦琐的电缆。主网关是家庭主网和家庭外部公共网络或社区网络的接口，是真正意义上的家庭网关，而子网关是作为一个“设备”接入到家庭
2、主网中,它是家庭控制子网到家庭主网的接口。本文的家庭子网网关蓝牙模块采用CSR公司最近研发的第六代芯片BlueCore6，该芯片采用AuriStream技术，它是蓝牙处理语音传输方式的一个巨大突破，提供了更高的语音质量，并且功耗降低了40%，在远程控制方面采用PSTN（公共电话交换网）接入方式最为理想。关键词：蓝牙，嵌入式系统，μClinux，MCF5272，家庭网关ABSTRACTTheintelligencehousingisfollowingthecomputer,thecorrespondence,thenetworkandthecontroltechno
