/****************************************************************************************************************************
  WiFiStorage.ino
  For boards with WiFiNINA module/shield.

  Based on and modified from WiFiNINA library https://www.arduino.cc/en/Reference/WiFiNINA
  to support nRF52, SAMD21/SAMD51, STM32F/L/H/G/WB/MP1, Teensy, etc. boards besides Nano-33 IoT, MKRWIFI1010, MKRVIDOR400, etc.
