8. Solució De Problemes
| Problema | Causa possible | Solució |
|---|---|---|
| El dispositiu no s'encén. | No power, power switch off, faulty cable/battery. | Ensure USB-C cable is connected to a working power source or battery is charged and connected correctly. Check power switch (SW1) is in "ON" position. |
| Screen remains black after power on. | Device in flashing mode, firmware issue. | If intentionally flashing, this is normal. Otherwise, try restarting. If issue persists, consider re-flashing firmware (see Section 5.3). |
| LoRa communication issues. | Antenna not connected, incorrect frequency, firmware misconfiguration. | Verify antenna is securely connected. Check firmware settings for correct LoRa frequency (e.g., 915MHz or 433MHz) and parameters. |
| Wi-Fi/Bluetooth connectivity problems. | Incorrect network credentials, device out of range, firmware issue. | Ensure correct Wi-Fi SSID and password. Move device closer to access point. Check firmware settings for Wi-Fi/Bluetooth. |
