4.3 GPS and 4G Functionality
The Ublox MIA-M10Q GPS module provides accurate location data. The A7682E 4G module allows for cellular data connectivity, enabling internet access and other network-dependent applications. Configuration for these features will depend on the specific firmware and your cellular service provider.
5. Entretien
5.1 Gestion de la batterie
The LILYGO T-Deck Pro is equipped with a built-in 1400mAh battery. Charge the device using the USB Type-C port. To prolong battery life, avoid extreme temperatures and fully discharging the battery frequently. If the device becomes unresponsive, connecting it to USB power will typically wake it up.
5.2 mises à jour du micrologiciel
Firmware updates are crucial for performance improvements, bug fixes, and new features. Always refer to the official LILYGO GitHub repository or Wiki for the latest firmware versions and detailed update instructions. Incorrect firmware flashing can damage the device.

- Wiki: wiki.lilygo.cc/
6. Dépannage
- L'appareil ne s'allume pas : 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.
- Le GPS ne capte pas de signal : Assurez-vous que l'appareil dispose d'un 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.
- Problèmes liés au micrologiciel : 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.
