Hi all, I finally received my second R/C unit. My cameraman is ridiculously excited. I have just been setting up the master/slave configuration and I have run into a problem. The slave remote is controlling the gimbal and the camera settings but there is no video feed to the iPhone 6 I am using the run the app on the slave remote. All the telemetry is there...just no video. I was using this iPhone 6 just fine when I only had a single controller so it was all working well before the dual control set up. The status box in the top centre of the screen is solid red and says "no signal." The status light on the control unit is solid purple which is as it should be. I do have video to the iPad mini on the master remote. The corresponding top centre box there says "safe to fly - Non GPS" (I'm indoors). I have read the DJI wiki and watched a couple of tutorials and I appear to have done everything correctly so a bit baffled by this. Am I missing something really obvious? Cheers, Simon.
