How To Install Using Arduino Library Manager

Features

This WiFiMulti_Generic library is a simple MultiWiFi library to adapt ESP32/ESP8266 MultiWiFi feature of WiFi libraries to all other WiFi modules and libraries. The functions are similar and compatible to those of ESP32 MultiWiFi and ESP8266 MultiWiFi libraries to make life much easier to port sketches from ESP8266/ESP32.
