Decided to take advantage of a very calm evening tonight and go fly. Being new, I'm trying to get into a set preflight routine, which consisted of the following: Power on transmitter. Launch DJI app on phone. Turn on range extender. Turn on P2V+. Calibrate compass. So far so good. But when the app connects with the P2V+, things get strange. I see the live video feed from the camera, which is correct. But the Battery Level, GPS Status and SD Card icons stay grayed out and never 'turn on' to their normal blue color. So I power off the P2V+, and power it back on. Of course, this causes the phone to display loss of connection, but it eventually reconnects as it should. But still, the three icons are grayed out. And they stay that way for at least two minutes. So I cycle the power off/on the P2V+ once more, with the same results. And what gets really weird is the Camera Tilt Control. It's reversed. I try to aim the camera up, and it goes down. Try to go down, it goes up. So........ I power everything down (in the order you should at the end of a flight), pull the battery out of the P2V+ and the transmitter, and restart my phone. Only then, after a normal 'power-up' process, does everything appear to be functioning properly and I take off. Having never heard of this issue........ anyone have an idea as to the cause, as well as a solution (other that try, try again)?
