基于Bluetooth和ZigBee相结合的信息分发器的设计

为了方便用户在特定的场景获得必要的数据服务,考虑到ZigBee和蓝牙共存的可行性,设计出将两者相结合的低成本普适网络环境下的信息分发器系统.该系统的硬件体系由蓝牙、ZigBee、传感器等主要模块构成,ZigBee模块负责无线通信网的组网并通过UART口和蓝牙模块通信,蓝牙模块运用蓝牙对象交换协议OBEX(object exchange)～r中的应用OPP(object push profile)对象"推"送规范来向蓝牙用户发送文件,改进了OPP推送算法来提高传输速率.

Design of information distribution based on combination of Bluetooth and ZigBee

In order to convenient for users to get necessary data services in some scene,taking into account the feasibility of co-existence between ZigBee and Bluetooth,a low-cost universal information network environment distributed system is built combining ZigBee with Bluetooth.The hardware of this system includes Bluetooth,ZigBee and sensor modules,ZigBee is responsible for wireless communi-cations network and through the UART port communicate with Bluetooth module.Bluetooth module send the file to the user using...
