6. Penyelesaian masalah
- Peranti tidak dihidupkan: Connect the device to a USB Type-C power source. If it still doesn't respond, try pressing the RST (Reset) button, usually located near the QWIIC connector.
- E-Paper display issues: E-Paper displays have a refresh cycle. If the display appears ghosted or unresponsive, a full refresh cycle (often triggered by a screen update or reset) may resolve the issue.
- LoRa communication failure: Ensure both devices are within range, configured to the same frequency (915Mhz), and using compatible firmware settings. Check antenna connections.
- GPS tidak menerima isyarat: Pastikan peranti mempunyai jelas view of the sky. GPS signal acquisition can take several minutes, especially during the first use or after a long period of inactivity.
- 4G connectivity problems: Verify that the SIM card is correctly inserted, active, and has a data plan. Check network coverage in your area.
- Isu berkaitan perisian tegar: If the device behaves unexpectedly after a firmware update, try reflashing the firmware or reverting to a known stable version. Consult the official GitHub or Wiki for specific guidance.
