My dji GO App has somehow determined that it is linking to a P3P ( I have a P3A). Whenever I turn on the aircraft, it goes through the gimbal self-check and then it just goes limp and the red light on the front of the gimbal flashes. The tablet/phone auto links ok, but it identifies the machine as a P3P. I've tried all the ribbon cable connections in the gimbal after I had to replace it and a yaw arm post crash. Any ideas?
