Parameters are the configuration settings of your drone. These allow you to configure your drone for various different flight settings, they are typically an important part of the setup procedure. The Parameters API allows you to set and get parameters without directly interfacing with your drone.
Due to the structure of parameters and the way that they are loaded, the API cannot guarantee that all params will always be loaded during initialization without perpetually requesting them from the drone infinitely. The API reports any params that it failed to load by their index numbers
