I recently flew about 600 Meters away, lost the video feed, stopped, flew in reverse for a 200-300 meters so that I could see the drone, and was surprised that I had to bring it all the way home with no videoFPV feed.
(I have P3S, stock RC no embellishments, iPad Mini 4, flight control is with the Litchi app)
My understanding...the traffic that moves over the WiFi is of three types:

My understanding...the traffic that moves over the WiFi is of three types:
- Flight commands instructing the drone to take off, go forward, left, right, up, down, yaw left, etc. primarily goes from the remote control(basic stuff)--->drone or from the smartdeviceapp(complex movements, orbits, designed flight plans, etc)--->drone.
- Telemetry information, primarily flows from the drone back to the smartdeviceapp for display to the pilot.
- Video flows from the drone to the smartdeviceapp for display as the pilot's FPV. It can also be recorded along with the telemetry in the smartdevice's storage, does not require the WiFi.
- Video is also captured in the drone's camera on a MicroSD card for post processing after the flight and does not require the WiFi network.
- Is my understanding close?
- When I fly far enough away to lose the video FPV feed (and am now blind), how do I get the video link to reestablish itself? I thought it would be automatic once I got the drone in closer.
- Can I turn the RC OFF(which will cause RTH to start) and back ON in order to force the video connection to re-establish? Will I be able to reacquire control of the drone and interrupt the RTH?
- Should I have put the iPad Mini 4 to sleep intending that the it would try to reestablish the video connection when it woke up.
- Is there an entity on this WiFi network that's in charge of keeping things running properly? Who keeps the video link running?
