[ESP32 on PlatformIO] error: conflicting declaration of C function 'sint8 close(SOCKET)' and 'class WiFiUDP' after Importing ArduinoOTA after WiFi.h #178

Closed TNeutron closed 1 year ago

TNeutron commented 1 year ago

I am getting the following error while trying to implement ArduinoOTA in my existing project that uses MQTT, NFC/RFID, TFT display, and a few buttons.

I have the following order of library imports.

#include <Arduino.h>
#include <WiFi.h>

#include <ESPmDNS.h>
#include <WiFiUdp.h>
#include <ArduinoOTA.h>

#include <pgmspace.h>
#include <TFT_eSPI.h>
#include <MFRC522.h>
#include <SPI.h>
#include <ESP32Time.h>
#include "Adafruit_MQTT.h"
#include "Adafruit_MQTT_Client.h"

I am consciously removing WiFi101 library from PlatformIO project library list but however, but it keeps coming back again and again after each complication. My assumption is that ArduinoOTA has a dependency on WiFi101 and that results in this conflict, with the Wifi.h Library.

How to solve this issue?

JAndrassy commented 1 year ago

don't use this library with esp32 WiFi

TNeutron commented 1 year ago

don't use this library with esp32 WiFi

The code examples in the Arduino library also use the WiFi library like 

#include <WiFi.h>
#include <ESPmDNS.h>
#include <WiFiUdp.h>
#include <ArduinoOTA.h>

But using this same pattern. I have found that working but the same pattern in my other project (in PlatformIO) seems to be causing this issue. Any thoughts on that?

EDIT: Oh, this is not recommended in PlatformIO. Missed that. Thanks for quick response anyways.

JAndrassy commented 1 year ago

use the ArduinoOTA library bundled with the esp32 platform
