Hi all, A strange thing happened today. I have had no issues with any of my Inspire equipment ever in about 70 flights, then after lunch went out to get some flying in. Two batteries and everything was humming! Thought I would go one last battery, inserted the battery, turned on the Inspire, the RC green light came up but the Pilot App was showing as "Disconnected" and no video feed from the camera. Restart a few times and no change. Try both used batteries back in the Inspire, still disconnected and no video!! The weird thing is that I can still tilt the camera using the RC jog dial and even start and stop the props (too scared to take off). Reset everything a couple of times, no change. Try a different lightning cable in my iPad mini, no change. Connect the second RC to the Inspire and a video feed comes up!! I've read various posts about faulty USB port on the RC but is this symptom indicative of a dodgy port? Appreciate any advice before I send it back to DJI.
