I am having a big problem. (No preview on the app.) No live feed on my phone from the camera - Get Black Screen with spinning wheel. - Able to configure the camera - Able to format sd card - Camera moves up and down - App shows all the information - All the other functions work (taking pictures, filming, number of GPS's, Altitude, etc) - Tried on iPhone 5s, 5, iPad Air, Droid phone. - Newest app from App Store. - Tried to reset the wifi extender. - Tried with the old plane software (although the camera software was already updated) - Updated all airplane software including the camera and remote... - Tried resetting re-biding the camera with the wifi extender. - Tried all possible sequence of steps to turn on including the one in the manual. - Tried to put the phone in Airplane mode - Tried to go where there is no other wifi interference. - Tried to fly with it for while filming and taking pictures to see if would work - Tried renaming the wifi extender - Tried replacing the cables (power and data original from dji) - Tried different batteries. --> Just about everything that I found on the forums so far I have tried... I have tried all those different steps and so far and no luck... Next step try other cameras (dii Visio FC200's) and wifi extender combinations. Not sure what else to try to make this work... Any suggestions?
