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: [Select all] [Expand/Collapse]

1. #include <WiFi.h>
2. Serial.begin(115200);
3. Serial.println();
4. Serial.print("ESP Board MAC Address:  ");
5. Serial.println(WiFi.macAddress());

as to make this with the correct esp_wifi.h

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.
