调用esp_wifi_start()来启动wifi,启动wifi之后就会进入esp_event_loop_init()创建的事件里面。 4、启动扫描周围wifi(这一步不是必须的,实现前面三步就可以实现wifi连接) 调用esp_wifi_scan_start(const wifi_scan_config_t *config, bool block);启动扫描 typedef struct { uint8_t *ssid; /**< SSID of ...

如下图,USER CODE 调用 ESP-NETIF 中的 API 接口初始化 TCP/IP 协议栈,之后调用 esp_wifi 中的API接口初始化wifi硬件,然后就能进入数据的收发过程。 在这里插入图片描述 我们这里只是简单的了解了一下 ESP-NETIF 是什么,为了我们能够理解下面介绍的 WiFi 的使用步骤,具体的内部实现暂时不做深究。
