ESP32 HUZZAH 32 // CONNECT TO WIFI

Post by pkgalanis04 »

"Firmware Tool: InvalidStateError: Failed to execute 'open' on 'SerialPort': The port is already open."

When I compile I get this :
Compilation error: AdafruitIO_WiFi.h: No such file or directory

Do you have a terminal or the Serial Monitor open on that port? Only one program can have a port open at a time.

As for the compile error, have you installed all the required libraries?

This is the sub-forum for the Adafruit IO WipperSnapper firmware and the IO pages related to it. Is the sketch you're attempting to compile the WipperSnapper demo sketch?
