/****************************************************************************************************************************
nRF52_ESP8266Shield.ino
For nRF52 boards using ESP8266 AT WiFi Shields, using much less code to support boards with smaller memory
ESP_AT_WM_Lite is a library for the Mega, Teensy, SAM DUE, SAMD and STM32 boards (https://github.com/khoih-prog/ESP_AT_WM_Lite)
to enable store Credentials in EEPROM to easy configuration/reconfiguration and autoconnect/autoreconnect of WiFi and other services
without Hardcoding.
