/*********************************************************************************************************************************
  SAMD_WiFiNINA.ino
  For SAMD boards using WiFiNINA Modules/Shields, using much less code to support boards with smaller memory
  
  WiFiManager_NINA_WM_Lite is a library for the Mega, Teensy, SAM DUE, SAMD and STM32 boards 
  (https://github.com/khoih-prog/WiFiManager_NINA_Lite) to enable store Credentials in EEPROM/LittleFS for easy 
  configuration/reconfiguration and autoconnect/autoreconnect of WiFi and other services without Hardcoding.
