Wi-Fi 库

[English]

概述

Wi-Fi 库支持配置及监控 ESP32-S2 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-S2 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-S2。

• station/AP 共存模式（ESP32-S2 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。

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!
