摘要
针对物联网系统中硬件设备缺少人机接口而导致Wi-Fi网络配置过程繁琐的问题,基于Wi-Fi监听模式提出一种低成本、高效率、普遍适用的Wi-Fi设备配网方法。该方法将配网数据封装到802.11数据帧的目标MAC地址中进行传输,Wi-Fi设备利用监听模式抓取这些802.11数据帧,从而实现配网数据的传递。通过对编码规则和配网数据包结构进行约定,并解决信道锁定问题,形成了一套完整的配网协议,实验证明该方法不仅配网方便、快捷,更能够实现批量配网。
Because of hardware devices in IoT system lacking man-machine interface,Wi-Fi network configuration is inconvenient.A low-cost,high-efficiency and universal Wi-Fi device network configuration method based on Wi-Fi monitor mode is proposed.The method encapsulates network configuration data into the destination MAC address of the 802.11 frame for transmission,and Wi-Fi device works on monitor mode to capture these 802.11 frames at the same time,therefore,it achieves transmission of network configuration data.This paper designs a protocol for network configuration that include coding rules,packet structure and channel locking process,and solves the problem of channels locking.The experiment proves that this method not only makes network configuration convenient and fast,but also can configure multiple devices at the same time.
