Parrot asks you to switch off your device’s Wi-Fi connection when flying your ANAFI series drone with both the Parrot Skycontroller 3 and your phone or tablet:
With this configuration, the drone and the controller communicate through the drone’s Wi-Fi network and activating your device’s Wi-Fi can only result in interferences.
Therefore, your device’s Wi-Fi should only be activated – and connected to your drone’s Wi-Fi network – when you want to fly the drone using your device as its sole controller.
