M5Stack ToughC5 Weatherproof IoT Dev Kit (ESP32-C5) · File : toughc5-ble-sensor-hub.ino · Language : Arduino C++ · Use case : Agir comme un hub BLE pour collecter les données d'un capteur environnemental externe.

BLE 5.0 device scanning and displaying MAC addresses and RSSI on the IPS screen.

Uses the native BLE stack of the ESP32-C5. Active mode improves detection but consumes more power. The touchscreen allows visual validation of nearby sensors. Ideal for IoT troubleshooting.
