WiFi' was not declared in this scope #143
Description
Hello dear team,
I have been trying for hours to flash my ESP32 via Arduino ID exactly according to the instructions.
Unfortunately, I always get an error message when checking in Arduino. Unfortunately I don't know what to do.
I hope someone can help me.
Thanks in advance.
