Examples

Connecting to WiFi station

#include <stdio.h>
#include "freertos/FreeRTOS.h"
#include "freertos/task.h"
#include "wifi_handler_station.h"

void app_main(void)
{
    while (1)
    {
        if(start_wifi_station("{\"c\":2,\"s\":[\"D-Link\",\"Airtel\"],\"p\":[\"yadayada\",\"lololwrong\"]}") == WIFI_ERR_NOT_CONNECTED)
        {
            ESP_LOGE("err", "failed to connect to any wifi");
        }

        wifi_ap_record_t *ap_info = get_wifi_station_info();
        if (ap_info != NULL)
        {
            ESP_LOGI("info", "ssid: %s", ap_info->ssid);
        }
        ESP_LOGI("heap", "heap size: %f", (float)esp_get_free_heap_size() / 1024);

        vTaskDelay(5000 / portTICK_PERIOD_MS);

        stop_wifi_station();

        vTaskDelay(60000 / portTICK_PERIOD_MS);
    }
}

Starting an access point

#include <stdio.h>
#include "freertos/FreeRTOS.h"
#include "freertos/task.h"
#include "wifi_handler_access_point.h"

void app_main(void)
{
    while (1)
    {
        start_wifi_access_point("esp-test", "pass12345");
        
        wifi_ap_record_t *ap_list = scan_wifi_access_point();
        int ap_num = wifi_access_point_list_size();

        if (ap_list != NULL)
        {
            for (int i = 0; i < ap_num; i++)
            {
                ESP_LOGI("ap", "%s", ap_list[i].ssid);
            }
        }

        while (!is_wifi_station_connected());

        vTaskDelay(5000 / portTICK_PERIOD_MS);

        stop_wifi_access_point();

        vTaskDelay(10000 / portTICK_PERIOD_MS);
    }
}
