IEEE 802.15.4是由IEEE 802.15工作组管理的一个技术标准，它为低速无线个人区域网络 (LR-WPAN) 定义了物理层和介质访问控制 (MAC) 规范。因此，它构建了一个通用的标准MAC层，为ZigBee和Thread等协议奠定了基础，从根本上支持了再上层的协议栈。OpenThread是Thread®标准的开源版本，并在广泛支持的IEEE 802.15.4无线标准基础上生成。OpenThread协议可实现所有Thread网络层（IPv6、6LoWPAN、具有MAC安全性的IEEE 802.15.4、Mesh Link Establishment、Mesh Routing）和设备角色，同时还提供边界路由器支持。它需要的内存容量较小，并且具有高度可移植性，非常适合基于低功耗无线方式进行设备间通信的IPv6家庭应用。 基于意法半导体同类产品中最优秀的超低功耗STM32L4微控制器，STM32WB双核无线MCU通过OpenThread协议栈支持IEEE 802.15.4通信协议的单路和并发模式。可满足各种物联网应用的需求。并且是经过Thread认证的组件。
