I have a phantom 2 with NAZA-M V2 receiver with the 2 antennae. The receiver is the orange version and is d-Bus. I also have a DJI DJ6 controller. I am unable to get them to bind. Is this the correct controller? When I turn on the drone, the little red light in the battery compartment flashes. When I push the button for 2 seconds it starts to flash greenish yellow. I turn on the controller and go through startup and no binding occurs. The outside big red light flashes 4 times rapidly and continuously. I went into the Naza assistant to check out the settings.
