Blink example works in my windows arduino esp32 installation though...

[me-no-dev]

you have 2 sketches in the same folder
wifi.ino and WiFiClientBasic.ino

[zhivko]

So each ino must be in its own folder? This should be mentioned in readme.md. Does this limitation comes from arduino itselve?

…

[me-no-dev]

should not be mentioned in the readme because it's Arduino thing. But having two compilable files that implement the same functions (loop and setup) will throw error with any builder.
Sketches are kept in folders with names the same as the sketches

[zhivko]

OK, I put each ino in its own folder and trying WiFiScan example, I get this error in serial terminal and then wroom32 constantly reset itself - then I need to pull io0 to low so I can program it again.:

Sorry for not copy pasting error, but seems copy/paste in Serial monitor doesnt work...

[me-no-dev]

not enough power to your ESP ;) maybe better cable?

[zhivko]

Yeah - you are correct! I change power of my board from +3.3V pin of cp2102 usb to ttl adapter to +5V pin (I have LD1117V33 on board) and example now works! Yes Thank you!

I got the same error and it was only because I left a bracket open. Once I deleted the additional bracket, the issue solved immediately... just for the record
