Hi Mike,
If you try another device using PIX4Dcapture, you shall be able to start from there.
Just need to choose Phantom 3 Standard and start from there. In fact it is important that the DJI GO app does not run at the same time as Pix4Dcapture. The SDK (what allows the communication between the drone’s firmware and an app) cannot interact with both at the same time. Therefore it is essential to make sure DJI GO is not running in the background especially after connecting the device to the drone. On Android, you should check that this app is not selected as the default app when connecting.
