摘要
首先介绍基于ZigBee协议的OTA系统,并在CC2530F256硬件平台上进行验证。在Z-Stack协议栈中,设计出一种镜像页请求的空中下载(Over the Air,OTA)更新方式,并通过实验测试,与原有的镜像块请求方式进行了比较分析。实验结果表明,镜像页请求方式可以大大减少网络的更新流量,从而提高节点的更新效率。
OTA system based on ZigBee protocol is first introduced, and it is validated on CC2530F256 hardware platform. In Z-Stack protocol stack,an Over the Air(OTA) upgrade method of image page request is designed, and it is compared with the original image block request method by experiments. Experimental result shows that the method of image page request can greatly reduce the network update traffic and improve the upgrade efficiency of nodes.
