      class DJIRemoteController

      @interface DJIRemoteController : DJIBaseComponent
      Header:DJIRemoteController.h
      Inherits From:DJIBaseComponent
      Description:

      This class represents the remote controller of the aircraft. It provides methods to change the settings of the physical remote controller. For some products (e.g. Inspire 1 and Matrice 100), the class provides methods to manager the slave/master mode of the remote controllers. A remote controller is a device that can have a GPS, battery, radio, buttons, sticks, wheels, and output ports for video. The mobile device is connected to the remote controller, which is always sending out information about what everything is doing. The normal remote controller is called the master. A slave wirelessly connects to the master remote controller at 5 GHz, and the aircraft can also download information to the slave. The slave can send gimbal control commands to the master. This configuration allows one person to fly the aircraft while another person controls the gimbal. This object is available from the DJIAircraft subclass off DJIBaseProduct.

      } DJIRCFocusControllerState
      Header:DJIRemoteControllerBaseTypes.h
      Description:

      Remote Controller's Remote Focus State. The focus product has one dial (focus control) that controls two separate parts of the camera: focal length and aperture. However it can only control one of these at any one time and is an absolute dial, meaning that a specific rotational position of the dial corresponds to a specific focal length or aperture. This means that whenever the dial control mode is changed, the dial first has to be reset to the new mode's previous dial position before the dial can be used to adjust the setting of the new mode. Example workflow:

      1. Use dial to set an Aperture of f2.2
      2. Change dial control mode to focal length (set DJIRCFocusControllerControlType)
      3. Use the dial to change the focal length
      4. Change dial control mode back to aperture
      5. Adjust dial back to f2.2
      6. Now the dial can be used to adjust the aperture.

      Struct Members:
      BOOL isWorkingYES if the focus control works. The control can be either changing the Aperture or Focal Length. If it is NO, follow the DJIRCFocusControllerDirection to rotate the Remote Focus Device until it turns to YES again.
      DJIRCFocusControllerControlType controlTypeRemote Focus Control Type.
      DJIRCFocusControllerDirection directionRemote Focus Control Direction. Use this with the isWorking value. It will give you the correct rotation direction when isWorking is NO.

      Description:

      Determines if multi-device pairing supported by the remote controller. When the remote controller supports multi-device pairing, it can be paired to more than one device (e.g. aircraft, RTK base station) at the same time. When this feature is supported, use startMultiDevicePairingWithTarget:withCompletion and stopMultiDevicePairingWithCompletion to start and stop pairing instead of using the following methods:
      - startPairingWithCompletion
      - stopPairingWithCompletion
      - getPairingStateWithCompletion. This feature is only supported by Phantom 4 RTK.

      Return:
      BOOLYES if multi-device pairing is supported.
      method startMultiDevicePairingWithTarget:withCompletion
      - (void)startMultiDevicePairingWithTarget:(DJIRCPairingDevice)target

      Header:DJIRemoteController.h
      Description:

      Starts pairing a target with the specific type (aircraft or RTK base station). This paring method is for Phantom 4 RTK only. To use RTK feature with a base station, the Phantom 4 RTK remote controller need to pair both the base station and the aircraft at the same time.
      CAUTION: pairing an RTK base station will unpair the paired aircraft. Therefore, to use the base station properly, the user needs to pair the base station first, and the aircraft after. It is only supported when isMultiDevicePairingSupported returns YES.

      Input Parameters:
      DJIRCPairingDevice targetThe device target to start multi-device pairing.
      DJICompletionBlock completionCompletion block.
      method stopMultiDevicePairingWithCompletion

      Input Parameters:
      DJICompletionBlock completionCompletion block.

      Description:

      Enables the RTK channel on the remote controller. When RTK air system is using the base station as the reference station, the remote controller should enable the RTK channel and reserve some bandwidth for data transmission between the base station and the air system.
      CAUTION: toggling RTK channel will reset the airlink between the remote controller and the aircraft. The airlink may take 3 seconds to recover. DO NOT enable/disable the channel when the aircraft is flying. If the base station is reconnected, you need to call this interface to enabled the RTK channel again. Only Supported by Phantom 4 RTK.

      Input Parameters:
      BOOL enabledYES to enable the RTK channel on the remote controller.
      DJICompletionBlock completionCompletion block.
