PlatformIo ESP8266Wifi.h Using Problem

adolphe · June 22, 2022, 2:07pm

Hello,

While coding with PlatformIo, the ESP8266Wifi.h library gives an error while compiling. It may cause problem.

#include <Arduino.h>
#include <ESP8266Wifi.h>


void setup() {
  // put your setup code here, to run once:
}

void loop() {
  // put your main code here, to run repeatedly:
}

I cannot reproduce this issue with the platformio.ini

[env:nodemcuv2]
platform = espressif8266
board = nodemcuv2
framework = arduino
lib_deps =
   me-no-dev/ESP Async WebServer@^1.2.3

and the same source code as you.

What’s your platformio.ini?

Why does it throw an error when adding #include <ESP8266Wifi.h> I’ve searched everywhere and can’t find it.

Please remove the folders

and retry building.

I uninstalled and reinstalled the IDE via Visual Studio Code. I deleted the folders in the directory you mentioned. Probably no problem. If so, I’ll post here again. Thank you. For quick turnaround and support. You’re welcome. Warm greetings from Turkiye…
