- Device not charging via USB-C: Check the USB-C cable and port for damage. Try a different cable or power adapter. Ensure the MeshPocket itself has sufficient charge.
- MeshPocket not recharging: Verify the USB-C cable and power source are functional. The charging indicator light should illuminate when charging.
5.2 Meshtastic Connectivity Issues
- Unable to pair with app: Ensure Bluetooth is enabled on your smartphone and the MeshPocket is powered on. Restart both devices and try pairing again.
- No messages being sent/received: Verify that the LoRa region settings in the Meshtastic app match your geographical location. Check the device's E-Ink display for any error messages or low battery warnings. Ensure other Meshtastic nodes are within range.
- Firmware update failure: Double-check that the correct firmware file for your MeshPocket model was selected. Ensure the device entered DFU mode correctly (double-press RST button).
5.3 E-Ink Display Issues
- Display not updating: The E-Ink display consumes power only during updates. If information seems stale, try pressing the USER button to refresh the display or check for new messages in the Meshtastic app.
