Do you have a friend with android?
The reason I ask, is there is an app ( android only ) IOS banned all such apps from their database! Anyhow the android APP, tracks wifi signals,
DJI's wifi CODE, is
( 60:60:1f:??:??:?? )
The 6 question marks are your unique MAC ADDRESS!
This will provide 2 things:
A) if it can track your cameras code ( then wifi board is working )
B) can obtain the unique MAC ADDRESS on any camera ( don't spread this info around too much PLEASE )
If you send me a PRIVATE, conversation request, I'll fill you in!
Also
I did not know what your original problem was? Can you fill me in on the story, and what you've done so far!
Lastly, you will need a new gimbal BOTTOM mount, if the pin has broken off! Also USUALLY when that happens, it also STRIPS OUT, the servo cam ( little clear/white plastic piece behind rubber cover, and screw ) this is most likely why your camera is pointing straight down!
