摘要
针对目前尚无支持OpenThead协议的边界路由器这一问题,提出并验证一种OpenThread边界路由器设计方案。采用树莓派作为边界路由器的主机端,通过以太网口连接外部IP网络,通过内置WiFi连接专员认证设备;采用德州仪器CC2538微控制器作为边界路由器的协处理器端,接入OpenThread网络;边界路由器的主机端和协处理器端通过USB连接。实验结果表明,该OpenThread边界路由器功能能够实现,节点设备可通过边界路由器连接互联网,并允许外部OpenThread专员设备添加新节点到OpenThread网络中。
For solving the problem of no border router supporting OpenThead protocol at present,a design scheme of OpenThread border router was proposed and verified.Raspberry Pi was used as the HOST of border router,the external IP network was connected through Ethernet interface,and the commissioner devices were connected through the built-in WiFi.Using the Texas instruments CC2538 microcontroller as the Co-Processor of border router,the OpenThread network was accessed.The HOST and Co-Processor of border router were connected via USB.Experimental results show that the fundamental functions of OpenThread border router are achieved,node devices can connect to Internet through it,and external OpenThread commissioner is allowed to add new nodes to the OpenThread network.
