Opretholdelse
- Rensning: Brug en blød, tør klud til at rengøre enheden. Undgå at bruge væsker eller slibende rengøringsmidler.
- Opbevaring: Opbevar enheden et køligt, tørt sted væk fra direkte sollys og ekstreme temperaturer.
- Batteripleje: Ved langtidsopbevaring skal du sørge for, at batteriet er opladet til cirka 50%. Undgå at aflade batteriet helt i længere perioder.
- Firmwareopdateringer: Regularly check the official LILYGO GitHub repository for firmware updates to ensure optimal performance and access to new features.
Fejlfinding
Enheden tænder ikke
- Sørg for, at batteriet er opladet. Tilslut enheden til en 5V USB-strømkilde.
- Verify the power button/switch is correctly engaged.
No LoRa Communication
- Check if the LoRa antenna is securely connected.
- Verify your LoRa code and configuration against the examples provided on the GitHub repository.
- Ensure both transmitting and receiving devices are within range and operating on the same frequency.
Inaccurate GPS Readings
- Sørg for, at enheden har en fri og uhindret bane view af himlen.
- Allow sufficient time for the GNSS module to acquire satellite signals (cold start may take longer).
Visningsproblemer
- If the e-paper display is not updating, check the software controlling the display.
- Sørg for korrekt strømforsyning til enheden.
