The Yuneec Typhoon 500 G model which was the one that had the gopro gimble I remeber some of the guys had to downgrade their GoPros to make it connect so could be the same problem. You have to remember when those X-star Go's came out that was 5 or 6 years ago so the gopro firmware was much different back then.
I had it about 95% working and had to take some time off. you need the older app which there is a link in this thread, the app will ask you to scan the underside of the drone, when it does this scan the code on the gimble instead. that is as far as I got. doing this will allow the app to see the GoPro ()which has to be in the drone for anything to work).
I turned on the wifi. The app on here I think they are 2 are they both the same. My app doesn't ask for any password. When I first got it all the lights on the remote would light up green and now the middle one is all that will turn green. I have tried to rebound it again and my app wont let me do anything with the camera. I'm so lost with this. I really need some one on one help please.
I did not get asked for a password either. if I had time I would try to get mine going again. this post is about all the info you will get on this drone. as I think one post said there were not many made so not much is known.
