*** iOS 9 Compatible ***FPV Booster V3 includes FPV Camera and Flight Tracker (In-App purchase required), which is developed by the official DJI SDK. It's compatible for Phantom 2 Vision+ (Plus) V2 and V3.Please read the instructions CAREFULLY of each module in "Help" section to learn how they work. Both the app and support are in English only. Important Notes When you open the app first time, you need internet connection. Otherwise, there is an error message "App Register Failed: (ErrorCode: -1)". When you get this error message, make sure you have internet connection, then kill the app and restart the app again. When you switch back-and-forth between DJI VISION app and FPV Camera, you may need to kill DJI app from memory prior opening FPV Camera because of DJI app is locking up FPV connection in the background. Otherwise, you may see "Phantom Connection Broken" and "Video Signal Lost" messages.*** FPV Camera *** FPV Camera is an In-App purchase module (US$ 8.99 or equivalent). It brings a complete new FPV experience for flying your Phantom 2 Vision+ with innovative features. It does not intend to replace DJI VISION app, while certain features and settings of VISION app are excluded, such as Ground Station, Compass Calibration, Current RTH Altitude, Binding, Rename Ranger Extender SSID, etc.Navigation Mode:Google Map includes 3 indicators (Home, Pilot, Phantom) with auto-zoom and auto-rotate capabilities.

It maintains all your flight records at a glance with a complete automatic and transparent process WITHOUT any pilot intervention. It starts/stops logging flight data automatically upon start/stop motor, and records real time flight data in the app. You can review your flight records and playback flight path with telemetry data right after landing on your iDevice even without internet connection. You can also import or export flights logs to CSV files for further manipulation by third-party software (such as DashWare).*** Booster ***FPV Booster improves Wi-Fi video/telemetry connection (FPV, First Personal View) performance for DJI Phantom 2 Vision+ (P2V+) and the new P2V+ V3. It equips with a unique Smart Boost feature to boosts additional 50%-100% FPV range by a single click. We are the inventor of boosting Vision+ aircraft FPV performance from an app. It outperforms other booster and utility apps by reducing Wi-Fi interference. Normal Boost: It works better if you fly alone in wide open area without interference. Smart Boost: It keeps scanning and adjusting Wi-Fi signal in real-time to optimize FPV performance during flight. If it determines good Wi-Fi signal when P2V+ flying nearby, it would not turn on the booster until it's necessary to do so. It usually performs better in urban area with some sort of Wi-Fi, cell phones and other interference. Wi-Fi Channel: This setting allows you changing P2V+ Wi-Fi from channel-1 to channel-11 easily to minimize interference and the channel setting will be saved accordingly. Wi-Fi WPA Password: It allows you to add/change password and deny unauthorized access to your P2V+.
