CODE MẪU TEST WIFI CỦA ESP32 S3 TRÊN ARDUINO IDE:

/*

 *  This sketch demonstrates how to scan WiFi networks.

 *  The API is based on the Arduino WiFi Shield library, but has significant changes as newer WiFi functions are supported.

 *  E.g. the return value of `encryptionType()` different because more modern encryption is supported.
