I'm running a P2 with the Zenmuse H3-3D gimbal and a GoPro 4 Black + mini iOSD + Bluetooth Data Link + iPad Ground Station + Black Pearl FPV Diversity. For no apparent reason, other than a firmware update for the P2 last week, my video reception has ceased to work. I am still receiving all of the flight data from the mini iOSD but no video coming from the GoPro. It was working fine and then (I believe there was an update installed about the 12th of May) it just stopped working. I have gone through all of the cables and connections but no luck. I have also tried to bypass the FPV hub and go directly to the gimbal but no luck here either. Could it be the infamous USB ribbon?
