How to know each component is connected?

William Wong

Each component will be online after the aircraft has connected to the MSDK.
In MSDK v4, we can use the onComponentChange callback from the SDKManagerCallback to know if the component is connceted.
In MSDK v5, we can setup a listener to each component's KeyConnection, true means connceted, false or null means disconnected.
ProductKey.KeyConnection means if the aircraft is connected.
AirLink.KeyConnection means if the airlink is connected.
Camera.KeyConnection means if the camera is connected.
Gimbal.KeyConnection means if the gimbal is connected.
FlightController.KeyConnection means if the flight controller is connected.
RemoteController.KeyConnection means if the remote controller is connected.
Battery.KeyConnection means if the battery is connected.
