# ESP32 WiFi Connect

This component helps with WiFi connection for the device.

It first tries to connect to a WiFi 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 WiFi network.

The URL to access the web server is `http://192.168.4.1`.

Here is a screenshot of the web server:

## Configuration

The WiFi credentials are stored in the flash under the "wifi" namespace. The keys are "ssid" and "password".

## Usage

```cpp

// Initialize the default event loop

ESP_ERROR_CHECK(esp_event_loop_create_default());

// Initialize NVS flash for WiFi configuration

esp_err_t ret = nvs_flash_init();

if (ret == ESP_ERR_NVS_NO_FREE_PAGES || ret == ESP_ERR_NVS_NEW_VERSION_FOUND) {

    ESP_ERROR_CHECK(nvs_flash_erase());

    ret = nvs_flash_init();

}

ESP_ERROR_CHECK(ret);

// Get the WiFi configuration

nvs_handle_t nvs_handle;

ret = nvs_open("wifi", NVS_READONLY, &nvs_handle);

// If the WiFi configuration is not found, launch the WiFi configuration AP

if (ret != ESP_OK) {

    // Blink blue LED to indicate that the device is in configuration mode

    auto& builtin_led = BuiltinLed::GetInstance();

    builtin_led.SetBlue();

    builtin_led.Blink(1000, 500);

    // Start the WiFi configuration AP

    WifiConfigurationAp::GetInstance().Start("ESP32");

    return;

}

nvs_close(nvs_handle);

    

// Otherwise, connect to the WiFi network

WifiStation::GetInstance().Start();

```
