M5Stack ToughC5 Weatherproof IoT Dev Kit (ESP32-C5) · File : toughc5_wifi6_scanner.ino · Language : C++ (Arduino) · Use case : Scanner les réseaux Wi-Fi disponibles en utilisant la capacité Wi-Fi 6 de l'ESP32-C5.

Demonstrates the dual-band (2.4/5 GHz) Wi-Fi 6 scanning capability of the ESP32-C5.

Uses the standard ESP32 WiFi library. The ESP32-C5 supports Wi-Fi 6; this scanner lists SSIDs, signal strength (RSSI), channel, and encryption type. No internet connection is required for scanning.
