Hi I have a Dji 3 SE and have been fixing it up, I have replaced the main centre board and everything powers up well however I am having no luck with pairing the remote with the RC. I have done everything that it tells me. However I don’t have the camera/Gimbal connected as it is no good. Would having the camera/Gimbal not connected have anything to do with it not pairing. Like does the camera need to be connect so you can pair it. Also another thing is if I have to replace the camera can I use a different model one or does it have to be the SE one. Any help on this would be great.
