🛠 Low-power Wi-Fi and Bluetooth management

M5Paper IoT Development Kit with 4.7-inch Touchscreen e-Ink Display · intermediaire · Connectez votre M5Paper au réseau tout en optimisant l'autonomie grâce au deep sleep.

Hardware: M5Paper, 2.4 GHz Wi-Fi router, smartphone with BLE app. 1. Use WiFi.h library to scan available networks. 2. Connect to a stable network and display the IP address on the e-Ink screen. 3. Enable Bluetooth with BLEDevice.h to send status notifications. 4. To save energy, configure 'light sleep' mode between data syncs. 5. Use timer wake-up to exit sleep every 10 minutes. 6. Verify consumption via USB current monitor if available. Deepening path: Integrate an external sensor via the Grove bus and send its data via MQTT.
