Returns the component index. Index is zero based. A component will have an index greater than zero when there are multiple components of the same type on the DJI product, and one of the components already has the index 0. For instance, M210 can have two gimbal mounted cameras, and will therefore have two gimbal components with indices 0 and 1, and two camera components with indices 0 and 1. For Matrice 600, there are printed numbers on the battery boxes. The Battery component instance with index 0 corresponds to battery compartment number 1. For Inspire 2 and M200 series, Battery with index 0 corresponds to the battery on the port (left hand) side of the aircraft. For M210 and M210 RTK, Camera and Gimbal with index 0 corresponds to the camera and gimbal on the port (left hand) side of the aircraft.
Returns the firmware version of the component. Each component will have a different firmware version, the combination of which will form the package firmware version getFirmwarePackageVersion found in BaseProduct.
