/****************************************************************************************************************************
ConfigOnSwitchFS_MQTT_Ptr.ino
For ESP8266 / ESP32 boards
ESP_WiFiManager is a library for the ESP8266/ESP32 platform (https://github.com/esp8266/Arduino) to enable easy
configuration and reconfiguration of WiFi credentials using a Captive Portal. Inspired by:
http://www.esp8266.com/viewtopic.php?f=29&t=2520
https://github.com/chriscook8/esp-arduino-apboot
https://github.com/esp8266/Arduino/blob/master/libraries/DNSServer/examples/CaptivePortalAdvanced/
Modified from Tzapu https://github.com/tzapu/WiFiManager
and from Ken Taylor https://github.com/kentaylor
Built by Khoi Hoang https://github.com/khoih-prog/ESP_WiFiManager
Licensed under MIT license
*****************************************************************************************************************************/
/****************************************************************************************************************************
This example will open a configuration portal when no WiFi configuration has been previously entered or when a button is pushed.
It is the easiest scenario for configuration but requires a pin and a button on the ESP8266/ESP32 device.
The Flash button is convenient for this on NodeMCU devices.
Also in this example a password is required to connect to the configuration portal
network. This is inconvenient but means that only those who know the password or those
already connected to the target WiFi network can access the configuration portal and
the WiFi network credentials will be sent from the browser over an encrypted connection and
can not be read by observers.
The Credentials, being input via Config Portal, will then be saved into LittleFS / SPIFFS file,
and be used to connect to Adafruit MQTT Server at "io.adafruit.com" and publish a Temperature Topic
Based on original sketch posted by user "wackoo" on https://forum.arduino.cc/index.php?topic=692108
