# Wi-Fi 库

[English]

## 概述

Wi-Fi 库支持配置及监控 ESP32 Wi-Fi 连网功能。支持配置：

- station 模式（即 STA 模式或 Wi-Fi 客户端模式），此时 ESP32 连接到接入点 (AP)。

- AP 模式（即 Soft-AP 模式或接入点模式），此时基站连接到 ESP32。

- station/AP 共存模式（ESP32 既是接入点，同时又作为基站连接到另外一个接入点）。

- 上述模式的各种安全模式（WPA、WPA2、WPA3 等）。

- 扫描接入点（包括主动扫描及被动扫描）。

- 使用混杂模式监控 IEEE802.11 Wi-Fi 数据包。

## 应用示例

ESP-IDF 仓库的 wifi 目录下提供了演示 Wi-Fi 库功能的几个应用示例，请查看 README 了解更多详细信息。

### Header File

- components/esp_wifi/include/esp_wifi.h

- This header file can be included with:

  >     #include "esp_wifi.h"

- This header file is a part of the API provided by the `esp_wifi` component. To declare that your component depends on `esp_wifi`, add the following to your CMakeLists.txt:

  >     REQUIRES esp_wifi

  > or

  >     PRIV_REQUIRES esp_wifi

### Functions

esp_err_t esp_wifi_init(const wifi_init_config_t *config)

  Initialize WiFi Allocate resource for WiFi driver, such as WiFi control structure, RX/TX buffer, WiFi NVS structure etc. This WiFi also starts WiFi task.

  Attention

    1. This API must be called before all other WiFi API can be called

  Attention

    2. Always use WIFI_INIT_CONFIG_DEFAULT macro to initialize the configuration to default values, this can guarantee all the fields get correct value when more fields are added into wifi_init_config_t in future release. If you want to set your own initial values, overwrite the default values which are set by WIFI_INIT_CONFIG_DEFAULT. Please be notified that the field 'magic' of wifi_init_config_t should always be WIFI_INIT_CONFIG_MAGIC!

  Attention

    The home_chan_dwell_time needs to be a minimum of 30ms and a maximum of 150ms.

  Attention

    Set any of the parameters to 0 to indicate using the default parameters - scan_time.active.min : 0ms, scan_time.active.max : 120ms home_chan_dwell_time : 30ms scan_time.passive : 360ms

    Whether MBO is enabled for the connection. Note that when mbo is enabled, the application itself should not set specific bssid (i.e using bssid_set and bssid in this config)or channel to connect to. This defeats the purpose of a MBO supported network, and hence if btm is supported and a specific bssid or channel is set in this config, it will be cleared from the config at the first disconnection or connection so that the device can roam to other BSS. It is recommended not to set BSSID when MBO is enabled. Enabling mbo here, automatically enables btm and rm above.
