Arduino R4 WiFi

Hi!
I have a sketch for Arduino R4 WiFi. This sketch compiles fine in the Arduino IDE.
In Visual Studio, I get this error:
fatal error: WiFiS3.h: No such file or directory
#include "WiFiS3.h"
Why?
I only get this kind of error on R4 WiFi.

Thanks in advance.

Thanks for the report.

Can you enable the below options in Visual Micro:
  • vMicro > Compiler > Verbose
  • vMicro > Compiler > Show Build Properties


Then perform a build on the affected project, and attach the complete output as a text file for us to review?

If you can enable the File > Preferences > Verbose Output During "Compile" in the Arduino IDE and attach their log as well it will help greatly.

Thanks for the files, and we have replicated the issue on the same 2024.0722.05 version.

If you update Visual Micro to the latest version available from our Downloads Page, the sketch will compile as expected:
https://www.visualmicro.com/page/Arduino-Visual-Studio-Downloads.aspx

If for some reason you do not want to upgrade, you should be able to workaround the problem by adding the #include "WiFiS3.h" above #include <ArduinoBLE.h> in your INO sketch.

I updated Visual Micro, with no changes, but the second option:

by adding the #include "WiFiS3.h" above #include <ArduinoBLE.h> in your INO sketch.

Works fine, thank you very much!

Have a nice day!
