void setup() {}

void loop() {}

Resulting error:

File paths:

What should I try next?

2

What is the file path of your sketchbook folder ?

3

The error message also tells you it is using: C:\Users\user\Documents\Arduino\libraries\

My question was intended to be a hint as to the problem

5

Too subtle - for me anyway :slight_smile:

It's in both places though.

Deleted the local version. Now this error:

21-3-12_MainTransmitterReceiver:4:31: fatal error: ESPAsyncWebServer.h: No such file or directory
compilation terminated.
exit status 1
ESPAsyncWebServer.h: No such file or directory

Yet, that file is here:

H:\Arduino\libraries\ESPAsyncWebServer\src\ESPAsyncWebServer.h

Can you please answer the question posed in reply #1

H:\Arduino

I thought that was implied.

Thank you

Your .ino file is in a folder in C:\Users\user\Documents\Arduino\ so that is your sketchbook directory. What does File/Preferences show as your sketchbook directory ?
