Check and update UNO R4 WiFi firmware

unoR4WiFi_CheckWiFiFirmware.ino run on my dev.board - Nologo UNO R4 WiFi, to check the on board WiFi Firmware version.

/*
  Simple code to check WiFi Firmware on Arduino Uno R4 WiFi

  Wi-Fi support is enabled via the built-in WiFiS3 library that is shipped 
  with the Arduino UNO R4 Core. 
  Installing the core automatically installs the WiFiS3 library.

If not updated latest version, update firmware in Arduino IDE 2, Tools > Firmware updater, refer to the video below.
