M5Stack PaperDIY Assembly Kit (ESP32-S3) · File : wifi-scan-connect.ino · Language : C++ (Arduino) · Use case : Scanner les réseaux WiFi disponibles et se connecter à un point d'accès connu.

Initializes the ESP32-S3 WiFi 4 module for network connectivity.

Uses the standard Arduino WiFi library. The PaperDIY uses an integrated PCB antenna. Ensure WiFi credentials are correct. The e-paper display is used for visual feedback.
