Well, that's odd. I can connect to the IQ4, I can control the back, and I can activate live view. Am I doing something wrong?
However: I currently don't have a camera/lens combo to attach the IQ4 to. So when activating live view, obviously I'm getting a black screen. When I trigger the camera, black RAW files are transfered to the iPad
Normally, I'll be receiving a lens/cam combo by the end of March so I'll test again as soon as possible.
I can also hook up the GFX100 II to the iPad using USB and activate wireless on the IQ4, and both show up as cameras I can connect to in C1 mobile. I can connect and disconnect each camera at will, no crashes or weird behaviour so far. I can shoot a small video with my phone if anybody wants to see it in action.
