8 การแก้ไขปัญหา

This section provides solutions to common issues encountered during the use of the SIM7600G-H 4G HAT Module.

• Module not detected by Raspberry Pi/PC:
  • Ensure the module is properly powered. Check the power indicator LED.
  • If using pogo pins, verify secure contact and correct 5V/GND connections.
  • หากใช้ USB ให้ลองใช้พอร์ต USB หรือสาย USB อื่นดู
  • On Raspberry Pi, ensure the necessary drivers are installed and the kernel recognizes USB serial devices.
• ไม่มีการเชื่อมต่อเครือข่าย:
  • Verify that the SIM card is correctly inserted and active with a valid data plan.
  • Ensure the LTE antenna is securely connected to the MAIN port.
  • Check the network status indicator LED for activity.
  • Confirm that the correct APN settings are configured via AT commands.
  • Test the module in an area with good cellular coverage.
• GNSS positioning not working:
  • Ensure the GPS antenna is securely connected to the GNSS port.
  • Place the GPS antenna in an open area with a clear view ของท้องฟ้า
  • Verify GNSS is enabled and configured correctly via AT commands.
• Communication issues with AT commands (e.g., no response, garbled text):
  • Check the serial port settings (baud rate, data bits, parity, stop bits) in your terminal program.
  • Crucially, ensure hardware flow control is disabled on your host controller board or in your serial communication software. This is a common cause of issues.
  • Verify the correct serial port device is selected (e.g., /dev/ttyUSBn).
• Antenna connectors frequently detach:
  • These are small connectors and can be delicate. Ensure they are fully seated.
  • For permanent installations, a small amount of non-conductive adhesive (e.g., hot glue) can be used to secure the connectors after they are properly attached.
