Issue or Suggestion Description

Could you please elaborate on the functionality of join_mesh_without_configured_wifi in esp_mesh_lite_config_t (JOIN_MESH_WITHOUT_CONFIGURED_WIFI_INFO / CONFIG_JOIN_MESH_WITHOUT_CONFIGURED_WIFI_INFO)?

I want to ensure that a mesh network can form regardless of whether the root node is connected to a router. While I understand that join_mesh_ignore_router_status needs to be set to true for this scenario, the example configuration also sets join_mesh_without_configured_wifi to true for non-root nodes. Could you clarify why this setting is necessary or beneficial in such a case?

Your clarification will help in properly configuring and understanding the library's behavior in this context.

Thank you!

• JOIN_MESH_WITHOUT_CONFIGURED_WIFI_INFO 设置为 true：

  • 设备在上电执行 esp_mesh_lite_start 之后就会尝试加入 Mesh 网络，即使设备没有配网（没有路由器信息）。

• JOIN_MESH_WITHOUT_CONFIGURED_WIFI_INFO 设置为 false：

  • 设备如果已经配过网，存在路由器信息，那么设备在上电执行 esp_mesh_lite_start 之后就会尝试加入 Mesh 网络；
  • 如果设备没有配过网，不存在路由器信息，那么设备在上电执行 esp_mesh_lite_start 之后就不会尝试加入 Mesh 网络，除非收到配网信息之后，用户主动调用 esp_mesh_lite_set_router_config()； esp_mesh_lite_connect();

• join_mesh_ignore_router_status 设置为 true：

  • 指子节点尝试加入 Mesh 网络时，应当忽略根节点是否连接到路由器，即使根节点没有连接路由器，子节点与根节点 Mesh ID 保持一致其也可以加入到 Mesh 网络中。
  • 这个配置仅对于 no_router 示例里面的子节点有用，其他情况应当避免这个配置设置为 true。
