Sigh, looks like the wireless module may be buggered. I've got no image coming back to the app. Everything else works fine, camera takes pics and all the data is coming back just nno image. I've tried rebinding the camera no no avail. Sent a help request to dji so lets see what happens.

The bird is only a few months old with less than a dozen flights under it's belt and was working fine last flight. I switched it on and blank
To add insult to injury I just ordered a second battery . . .


EDIT: It's a Vision BTW
