“If you use ESP8266 with Arduino Core you will certainly be issuing instructions: WiFi.begin(SSID, Password). It can connect WLAN easily but the access point to be connected is fixed and inflexible.
Whenever the access point to be connected changes, do you rewrite the sketch and upload it?
You use AutoConnect as an Arduino library, you forget time and effort for the revising the sketch.
It an Arduino library united with ESP8266WebServer class. Easily implementing the Web interface constituting the WLAN for ESP8266 WiFi connection. With this library to make a sketch easily which connects from ESP8266 to the access point at runtime by the web interface without hard-coded SSID and password.”
