Our organization just purchased three new Mavic Pro 2's to add to our fleet, and this time around we purchased the Smart Controllers....which may have been a bad move. We use Pix4D for setting grids for aerial mapping, but it appears after installing the Pix4D app, it won't download maps because there's no GPS connectivity between the aircraft and the app? Has anyone had any luck downloading maps with Pix4D, or another like app?
