This component helps with Wi-Fi connection for the device.
It first tries to connect to a Wi-Fi network using the credentials stored in the flash. If this fails, it starts an access point and a web server to allow the user to connect to a Wi-Fi network.
The URL to access the web server is http://192.168.4.1.
- Add ja / zh-TW languages.
- Add advanced tab.
- Add "Connection: close" headers to save open sockets.
- Add support for language request.
- Add support for ESP32 SmartConfig(ESPTouch v2)
- Improve Wi-Fi connection logic.
- Add support for multiple Wi-Fi SSID management.
- Auto switch to the best Wi-Fi network.
- Captive portal for Wi-Fi configuration.
- Support for multiple languages (English, Chinese).
The Wi-Fi credentials are stored in the flash under the "wifi" namespace.
The keys are "ssid", "ssid1", "ssid2" ... "ssid9", "password", "password1", "password2" ... "password9".
// Initialize the default event loop

}

// Get the Wi-Fi configuration
auto& ssid_list = SsidManager::GetInstance().GetSsidList();

// Start the Wi-Fi configuration AP
auto& ap = WifiConfigurationAp::GetInstance();
ap.SetSsidPrefix("ESP32");
ap.Start();
return;
}
// Otherwise, connect to the Wi-Fi network
WifiStation::GetInstance().Start();
