5. Instruccions de configuració

5.1 Connexions de maquinari

1. Insereix la targeta SIM: Carefully insert a Nano SIM card into the designated SIM card slot on the board. Ensure correct orientation.
2. Inseriu la targeta TF (opcional): If using, insert a TF (MicroSD) card into the TF card slot.
3. Connecteu les antenes: Connect the LTE antenna to the main cellular antenna connector and the GPS antenna to the GPS connector. Ensure a secure connection.
4. Font d'alimentació: The board can be powered via the USB-C port or by inserting an 18650 battery into the battery holder on the back. The solar input range is 4.4V-6V.
5. Connexió USB: Connect the board to your computer using a USB-C cable for programming and serial communication.

5.2 Configuració del programari

1. Instal·leu els controladors: Ensure necessary USB-to-serial drivers are installed for your operating system (Windows, Linux, macOS).
2. Entorn de desenvolupament: Set up your preferred ESP32-S3 development environment (e.g., Arduino IDE with ESP32 board support, ESP-IDF).
3. Biblioteques: Install relevant libraries for the SIM7080G module and GPS functionality.
4. Firmware: Descarrega example code and firmware from the official LILYGO GitHub repository: github.com/Xinyuan-LilyGO/LilyGo-T-SIM7080G.

6. Instruccions de funcionament

6.1 Engegada/apagada

Use the integrated ON/OFF switch to control the board's power. When connected via USB, the board may draw power even if the switch is off, depending on the specific circuit design.

6.2 Programming the ESP32-S3

Connect the board to your computer via USB-C. Use your chosen development environment to upload your code. The board typically enters programming mode automatically, or you may need to press the BOOT button while resetting, depending on your setup and firmware.

6.3 Using Cellular (Cat-M/NB-IoT)

The SIM7080G module requires AT commands for communication. Refer to the SIM7080G documentation and LILYGO's examples for sending commands to initialize the module, connect to the network, and send/receive data. Ensure your SIM card is activated for Cat-M or NB-IoT services.

6.4 Using GPS

The integrated GPS functionality of the SIM7080G module can be accessed via AT commands. Ensure the GPS antenna is connected and has a clear view of the sky for optimal signal reception. Parse NMEA sentences from the module to extract location data.

8. Solució De Problemes

• Placa no reconeguda per l'ordinador:
  Ensure you have installed the correct USB-to-serial drivers for the ESP32-S3. Try a different USB-C cable, as some cables are charge-only. Verify the cable is securely connected.
• Failed to Upload Code:
  Check that the correct board and COM port are selected in your IDE. Ensure the board is in programming mode (sometimes requires holding the BOOT button while pressing RST). Verify power supply.
• No Cellular Network Connection:
  Confirm your SIM card is active and has a data plan for Cat-M or NB-IoT. Ensure the LTE antenna is properly connected. Check network coverage in your area. Verify AT commands for network registration are correct.
• GPS Not Acquiring Fix:
  Ensure the GPS antenna is connected and has an unobstructed view of the sky. GPS acquisition can take several minutes, especially on first use or after a long period of inactivity.
• Problemes d'alimentació:
  If using battery, ensure it is charged and correctly inserted. If using USB, ensure the power source provides sufficient current.

9. Manteniment

• Emmagatzematge: Store the development board in a dry, anti-static environment when not in use.
• Neteja: Use a soft, dry brush or compressed air to remove dust. Avoid liquids.
• Manipulació: Handle the board by its edges to avoid touching sensitive components, especially when powered.
• Actualitzacions de firmware: Regularly check the official LILYGO GitHub repository for firmware updates and examples to ensure optimal performance and access to new features.
