I have a friend who has a
Phantom 4 pro and is in a place with limited internet access. He sent me this text message and I was wondering if anyone had some ideas of how to proceed:
"I have an issue right now, hard to sort out with limited internet.
Seems to be no comms between controller / app & camera.
There is no picture, it says there is no SD card even when there is one, there is no battery % and no access to camera settings"
I have a
phantom 4 pro plus and, no difference with the P4pro except for the controller that come with a display attached. (no phone need it to fly).
The internet isn't needed to fly and keep and eye in your display. the other guys above my comments are right. you only need the internet to update the firmware if is available a update of the drone software.- If this is the case you can do this in home where you have wifi internet and update it before you go to fly.
the other scenario where you can need internet its when you want to transmit in your social media the feed of the filming. example facebook live or youtube live.- In this circumtances you need to connect the to wifi or carry your own internet provider in your phone to transmit in real time same as you do fb live in your phone. (explanation to do that its other conversation. no in this matter.)
The communication between the controller and the aircraft its via wifi (but no the wifi that you catch in home or other place) This this is provided by the satellites that track your drone and keep the connection with the controller. Beside the wifi its only to keep comunication between the display or controller with the aircraft but depending how far you are flying you can lost the signal or get flicking connection due the distance.--
The recording its storage in the aircraft micro sd card and also in the micro sd card in the controller. the difference its the resolution. drone sd card record in any resolution you set before hand (maybe 4K) but the sdcard in the controller just go untill hd 1080x1920 pixels.
You no need internet wifi in the enviroment to fly your drone and recording or take pictures.
If you damage the bay where the card slide in, its other thing. check with a new card. this is no a usual problem . I hope my words help you.
Try to unistall the DJI apps in your phone and reinstall it again and update the firmware and change micro sd cards for new ones. Sergio.
