I can not get my Phantom 3 4K connected to the Pix4D Capture application, Is the App compatible with the Phantom 3 4K?
We have not tested the Phantom 3 4K on our side, so we cannot give any guarantees on the compatibility.
However, I can recommend to select a drone in the settings (before starting the mission) that has a similar connection mode (Wi-Fi or USB cable) which would be the Phantom 3 Advanced or Professional in your case.

Maybe someone from the Community has experience with this drone and can give you more hints
