How do I update the firmware over the air?


Please update your device following these steps.

  • Go to Main menu-Service menu-Firmware update to update the device to the latest firmware.
  • Battery voltage should be 3.9V or more when updating. If not, firmware rewrite is not allowed due to security reasons. You can connect charger if in doubt.
  • The update takes about 3mins. And the size is 64 kByte.
  • Go to Main-Service menu-About to check the firmware version.

Please report the FW version in case of any issues.

We will notify you about new firmware releases via email and in the Checkfox dashboard.
