I just completed a new build and have the same problem as described above. Using a Makbook pro El Capitan (10.11.6). Using a thunderbolt ethernet adaptor. It appears to have connected and when I power up the topside board and the ROV the video comes through, but it says “Waiting for vehicle connection” in red over the top of the fly window in QRground control.
I followed Jacob’s instructions above and went to 192.168.2.2:8088 in a browser and opened the rpi terminal window and entered the command ‘screen -r mavproxy’. It showed this:

Flight battery warning
Received 691 parameters
Saved 691 parameters to mav.parm
Eventually it also added “Flight battery warning”, although I checked the voltage of the battery and it was still at 4.1 per cell. I am not using the battery it cam with, but a 4S 5200mah 25C lipo.
Any suggestions would be very welcome. Thanks!
