How To Install Using Arduino Library Manager

This library is a Light Weight Credentials / WiFi Manager for WiFiNINA modules/shields, specially designed to support AVR Mega, STM32, Teensy, SAM DUE, SAMD,  etc. boards running WiFiNINA modules/shields, with smaller memory (64+K bytes)

You can also specify static AP and STA IP. Use much less memory compared to full-fledge WiFiManager. Credentials are saved in EEPROM, FlashStorage or DueFlashStorage.

You can use this library when your boards have more than 32K bytes of memory, for example Mega1280, Mega2560.

The web configuration portal, served from the WiFiNINA modules/shields is operating as an access point (AP) with configurable static IP address or use default IP Address of 192.168.4.1
