🛠 Configure WiFi and Bluetooth 5.0 LE on the ESP32-S3
PaperDIY Assembly Kit · intermediaire · Établissez une connexion réseau fiable en exploitant les capacités du SoC ESP32-S3 et de son antenne PCB.
Include the WiFi.h and BLEDevice.h libraries in your Arduino project. Ensure the PaperDIY kit is powered via USB-C or the internal battery.
Configure WiFi settings for station mode. Use WiFi.begin(ssid, password) and implement auto-reconnect logic in case of signal loss.
For Bluetooth, initialize the BLE service. Create a virtual device with a custom service to transmit sensor data or screen status.
Manage radio interruptions: The ESP32-S3 shares the PCB antenna. If using WiFi and BLE simultaneously, test connection stability and adjust power settings if necessary.
Use the 8MB PSRAM to store network buffer messages if handling large data volumes, preserving critical SRAM.
Verify the connection via the serial monitor by displaying the obtained IP address and BLE scan status.
Deepen your knowledge: Implement Deep Sleep mode between connections to maximize the autonomy of the 140mAh battery.
