I was just wondering with the new firmware whether an OTG cable for IOS is useful to get better and longer range with the spark and stop loosing signal on the phone

Hi, thanks for for reaching DJI forum. Our latest firmware for spark is now supporting OTG cable, however, it's only available with Android device to provide a stable signal between your RC and phone that cannot easily be interrupted of those wireless interference. Rest assured that we will keep improving our products to provide more option in terms of compatibility. Thanks for your understanding.

So that means I still have to use WiFi between my controller and phone. Moreover, I saw a accessory for the drone controller called parabolic antenna booster. Would u recommend this to increase range of the drone

Also do u think I could still use a OTG cable to go to iOS even though it is not officially supported
