Hello everyone,

I am trying to build my first fpv quad, and already overcame a lot of problems. I changed the motor orientation and fc orientation, and wanted to testfly it. Yesterday everything was working fine (except the quad flipping on throttle probably because the fc orientation was wrong). Then I changed the fc orientatino and suddenly I don't get any inputs neither in bf nor can I arm the quad.
The vista is still connecting to the remote and the goggles and I also see the camera image and the custom osd I set up in bf. To connect the fc to the vista I used the cable that came with the fc, cut the end for the dji air unit off and soldered them to the vista. The connections are fine and not touching each other, and the remote already worked for quite a bit before now. I don't know whats wrong, in bf the uart 5 channels was automatically enabled for rx, and I enabled uart 2 for the osd, which worked fine for a bit.

All the parts I got:
Dji remote V1
Dji goggles V2
Iflight cidora
T-Motor F7 DJI HD Stack F55A V2
Iflight xing e 2207 1800kv
Caddx vista + polar cam
Cnhl 1300 mAh 6s black line

Thanks for all help
