esp_netif组件还处理Wi-Fi事件,以提供一组默认行为。例如,当Wi-Fi站连接到AP时,esp_netif将自动启动DHCP客户端(默认情况下)。 // 创建系统事件任务并初始化应用程序事件的回调函数。 ESP_ERROR_CHECK(esp_event_loop_create_default()); // 创建具有TCP / IP堆栈的默认网络接口实例绑定AP。 esp_netif_create...

三者之间有什么关系? esp_wifi驱动库用户控制wifi硬件单元; lwip是一层纯软件,轻量级TCP/IP协议栈; esp_netif是esp官方提供的操作TCP/IP协议栈的API 原文链接:https://blog.csdn.net/qq_34473570/article/details/108560904

Understanding that the DHCP server was not actually working I dumped esp_netif_get_ip_info() which reveals that the ESP has address 0.0.0.0 To intitialise DHCP I use: esp_netif_dhcps_stop(), esp_netif_set_ip_info(), esp_netif_dhcps_start() but the assigned address does not stick whe...
