# 无路由器示例

## 介绍

本示例将介绍如何快速组建一个无路由器 ESP-Mesh-Lite 网络，其余的组网方案及详细使用方式参见 [README](https://github.com/espressif/esp-mesh-lite/blob/master/examples/mesh_local_control/README_CN.md)，在运行本示例之前请详细阅读 [User Guide](https://github.com/espressif/esp-mesh-lite/blob/master/components/mesh_lite/User_Guide_CN.md)。

## 配置

运行本示例，您至少需要准备两块开发板，一块配置为根节点，其余为非根节点，本示例默认为非根节点类型。

- 根节点：一个 ESP-Mesh-Lite 网络中有且仅有一个根节点，通过 `MESH_LITE_ID` 和信道来区分不同的 `MESH-LITE` 网络
- 非根节点：包含叶子节点和中间节点，其根据网络情况自动选择父节点
	- 叶子节点：叶子节点不会做为中间节点，即不允许有下游链接

你需要通过 `idf.py menuconfig`(CMake)，在 `Example Configuration` 子菜单下，配置一个设备为根节点，其余设备为非根节点。
您也可以在 `Component config -> ESP Wi-Fi Mesh Lite` 子菜单下，配置 ESP-Mesh-Lite 的最大层级、`MESH_LITE_ID` 等参数。

## 运行

1. 初始化 Wi-Fi，根据配置启动 ESP-Mesh-Lite；
2. 创建定时器：定时打印 ESP-Mesh-Lite 网络的层级，父节点的信号强度及剩余内存。
