Thank you for the input.
That was not my question, though.
I do have a "proper" 1-foot cable on the way, one recommended for this function.
However I am trying things out with the cable I mentioned and the DJI GO 4 app on the iPad keeps reporting "Disconnected", without a camera image coming through.
I previously tested with a Galaxy 7.7+DJI Go and Galaxy Tab S 8.4+DJI GO 4 and everything was Ok, hence my question about the cable.
Are the ones coming with the charger "power only" cables?
Thanks
MK
