See post #37 in this very thread ...Hey,
I'm new to flying (and the forum), Just getting my head around the drone in general! I've bought an OTG cable as I felt that it's always better to have a hardwired connection to something as opposed to a wireless connection so I didn't think it would do any harm to try it!!
I have heard that DJI would take issue with any claim on the refresh insurance *if* you are using an OTG cable as it's not 'officially' supported? is this true?
