Make sure you have the latest version of AR.Freeflight.

You are informed that a new update is available when you start the application AR.FreeFlight

Press OK to start the update. If you press Cancel, the update will be offered again when you next start the application.

At the Installing stage, the application will ask you to restart the AR.Drone. At the Installing stage, the application will ask you to restart the AR.Drone. To do this, disconnect the device's battery then reconnect it. Wait until the LEDs turn green.

After the update has been installed on the AR.Drone, the drone is restarted.
Then the application is trying to reconnect to the drone using the FTP (file transfer protocole) functionnality provided natively on the iPhone to check the firmware version. Although the AR.Drone firmware has generally been successfully updated, it seems that iPhone's FTP fails reconnecting with the drone. The user could close AR.FreeFlight, reset Wi-Fi on the iPhone and restart the application so that FTP has a second chance to reconnect and check the firmware version.

The process to follow is:

• After 5 minutes without successfull reconnection, the user should check the led underneath.
• If led is green, then the firmware has been successfully updated. The user should close AR.FreeFlight, reset Wi-Fi on the iPhone and restart the application.
• If led is not green, then the firmware updating process failed. The user should reset the drone, reset Wi-Fi on the iPhone and restart the application to retry updating process.
