DJI Registration and Vision App
DJI requires all third-party applications to register upon installation, which requires a network connection. Autopilot performs the registration automatically in the background and does not require any input from the user. Autopilot will not be able to connect to your Phantom until the registration is complete. Furthermore, if the DJI Vision app is already connected to your Phantom, you will need to terminate the Vision app first in order for Autopilot to connect successfully.
