4. මෙහෙයුම් උපදෙස්

Once the board is set up and firmware is loaded, you can begin operation:

• බල ගැන්වීම: Connect the board to a power source. The OLED display should illuminate, showing information based on the loaded firmware (e.g., network status, messages for Meshtastic).
• OLED සංදර්ශකය: The 0.96 inch SSD1306 OLED display provides visual feedback. Its resolution is 128x64, and it uses an I2C interface (SDA-IO18, SCL-IO17).
• රැහැන් රහිත සන්නිවේදනය: Utilize the integrated Wi-Fi and Bluetooth 5.0 for local network connectivity or device pairing. The LoRa module (SX1280 2.4G) enables long-range, low-power communication.
• Reset and Boot Buttons: The board features a Reset button to restart the microcontroller and a Boot button, typically used for entering bootloader mode during firmware flashing.
• මෘදුකාංග අන්තර්ක්‍රියා: Interact with the board through its serial interface (via USB) or wirelessly, depending on the firmware's capabilities. For Meshtastic, a mobile application or web interface is commonly used.

5. නඩත්තු කිරීම

Proper maintenance ensures the longevity and reliable operation of your development board:

• වියළිව තබා ගන්න: Protect the board from moisture and humidity.
• මෘදු ලෙස පිරිසිදු කරන්න: Use a soft, dry brush or compressed air to remove dust. Avoid liquid cleaners.
• ස්ථිරාංග යාවත්කාලීන කිරීම්: Regularly check the official LILYGO GitHub repository (github.com/Xinyuan-LilyGO/LilyGo-LoRa-Series) for firmware updates and security patches.
• ඇන්ටෙනා සත්කාර: Ensure the antenna is securely connected but do not overtighten. Avoid bending or damaging the antenna.

6. දෝශ නිරාකරණය

If you encounter issues with your LILYGO T3S3 board, consider the following:

• පුවරුව ක්‍රියාත්මක නොවේ:
  • Verify the USB cable is properly connected to a working power source.
  • If using a LiPo battery, ensure it is charged and correctly connected to the battery switch.
• OLED Display Blank:
  • බල සැපයුම පරීක්ෂා කරන්න.
  • Ensure firmware is correctly loaded and configured to initialize the OLED.
• No Wireless Connectivity (Wi-Fi/Bluetooth/LoRa):
  • Confirm the antenna is attached correctly for LoRa.
  • Verify that the firmware includes the necessary drivers and configurations for the wireless modules.
  • දේශීය මැදිහත්වීම් සඳහා පරීක්ෂා කරන්න.
• Firmware Upload Issues:
  • Ensure correct drivers for the USB-to-serial chip are installed on your computer.
  • ඔබා අල්ලාගෙන සිටින්න බූට් කරන්න button while pressing and releasinජී ද යළි පිහිටුවන්න button, then release බූට් කරන්න to enter flashing mode.
