Phantom 4 pro remote controller connection error.
A few days ago i have faced the same problem that the remote controller is not connecting.
Both of these features operate at 2 4ghz.
It s a intermittent fault hard to find and dangerous.
Why would this happen.
Sometimes you are ready to fly but the dji go and go 4 apps state that your drone is disconnected.
When you unplug the cable in flight you get a disconnected error on phone screen and still have full control.
Dji go connection issues can be caused by faulty usb cables the remote controller s signal connection device compatibility and a few other reasons.
When return to home activates.
Make sure there is enough storage available on the sd card.
When i get the remote controller connection error i have no control.
The controller also includes a range of functions which give you greater control over the phantom 4 s camera.
I am searching on the internet how to solve this issue i find out this reddit discussion forum and according to deathxbyxtaxes i follow his instruction and now my drone problem has been solved.
