include wifi.h can't be resolved in VSCode

[hape65]

hi
i'm new to the ESP32 world. I have bought a few ESP32-C6-DevKitC-1.
I have managed to get the "helloworld" in VSCode to get build and flashed.
I have also managed to get the Hardware debugging to work.

But the simple

#include "wifi.h"

couldn't be resolved.

the includes:

#include <stdio.h>
#include <inttypes.h>
#include "sdkconfig.h"
#include "freertos/FreeRTOS.h"
#include "freertos/task.h"
#include "esp_chip_info.h"
#include "esp_flash.h"
#include "esp_system.h"
#include <esp_now.h>

work like a charm.

Astonishing for me also the

#include "C:/Users/"user"/esp/v5.2.1/esp-idf/components/esp_wifi/include/esp_private/wifi.h"

doesn't work.

What could be wrong or what should i do to get this to work.

thx for helping in advance

Why would you need wifi.h in the first place? The 'normal' way to include wifi functions is by including esp_wifi.h.

hi
thx for answering. I understood your point.
But for me (as a beginner in the ESP32 world) it seems to be easier to make

Code: Untitled.c Select all

#include <WiFi.h>

Serial.begin(115200);

Serial.println();

Serial.print("ESP Board MAC Address:  ");

Serial.println(WiFi.macAddress());

as to make this with the correct esp_wifi.h

Code: Untitled.c Select all

/*******************************************************************************************

            Code created by AI and OK1TK with support of the Espressive ESP32 forum

 *******************************************************************************************/

#include <stdio.h>

#include "esp_wifi.h"

#include "esp_log.h"

#include "nvs_flash.h"

void app_main()

{

    esp_err_t ret;

    //Initialize the default NVS partition.

    ret = nvs_flash_init();

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

        // If NVS initialization fails due to uncleaned pages or a new version, we clear NVS and try again

        ESP_ERROR_CHECK(nvs_flash_erase());

        ret = nvs_flash_init();

    }

    ESP_ERROR_CHECK(ret);

    // TCP/IP stack initialization

    esp_netif_init();

    esp_event_loop_create_default();

    // Initialization WiFi

    wifi_init_config_t cfg = WIFI_INIT_CONFIG_DEFAULT();

    ret = esp_wifi_init(&cfg);

    if (ret != ESP_OK) {

        ESP_LOGE("WiFi", "WiFi initialization FAILED!: %s", esp_err_to_name(ret));

        return;

    }

    // Retrieving the the MAC address of the WiFi interface

    uint8_t mac[6];

    ret = esp_wifi_get_mac(ESP_IF_WIFI_STA, mac);

    if (ret != ESP_OK) {

        ESP_LOGE("WiFi", "Unable to retrieve the MAC address of the WiFi interface: %s", esp_err_to_name(ret));

        return;

    }

    // Writing the MAC address of the WiFi interface to the terminal

    ESP_LOGI("WiFi", "The WiFi interface MAC address: %02x:%02x:%02x:%02x:%02x:%02x",

             mac[0], mac[1], mac[2], mac[3], mac[4], mac[5]);

}C:/Users/hape/.espressif/tools/xtensa-esp-elf/esp-13.2.0_20230928/xtensa-esp-elf/xtensa-esp-elf/include

it could be that i didn't understand the idea behind the esp_wifi.h . i found https://docs.espressif.com/projects/esp ... _wifi.html as documentation.

thx for clearing my confusionv in advance

Your first code sample is for the Arduino platform and the second is for ESP-IDF. The private wifi.h header in ESP-IDF isn't the same as the WiFi.h header in Arduino and including it won't provide any Arduino-like functionality for your code.
