Heltec WiFi LoRa 32 (V3) - Compilation error: Multiple libraries were found for "WiFi.h"

[joaopedros2]

I am using the following libraries in my sketch:

#include "LoRaWan_APP.h"
#include "Arduino.h"
#include <WiFi.h>
#include <PubSubClient.h>
#include <Wire.h>
#include "HT_SSD1306Wire.h"

and the error is as follows:

I reinstalled everything again to make sure there was nothing wrong with my Arduino on Windows, and after reinstalling everything, the only library I added was PubSubClient.h Any idea what could be causing this issue?

I get the same error when trying to run the DrawingDemo example. (among other issues)

Does anyone know which OLED libraries work together with these?

"LoRaWan_APP.h" "Arduino.h"

With this release, there needs to be a copy of esptool.py under the folder structure listed. I created the directory and copied esptool.py into it and had this error go away.

This method works in 0.0.7?
