Ok....So how do we make them talk? I’m sure that the connection between the two is ok since there are activities going on everytime i try to install a FW (but evertime i try, it fails). While holding the link button, power ON the AC, and not releasing until you hear the D-D sound on the gimbal which is an indication that the upgrade/downgrade has started. At this point the led light flashes red and green alternatively on the gimbal and the led lights on the AC shows some progress on how the FW is being installed. So somehow, they are communicating, right?
