    Description: 
    This header file contains necessary definitions
    and api functions for the Simply Blue bluetooth interface.

    The scope of this file is not to give a complete code compilable and 
    runnable, but deliver a framework to start with. The implementation of 
    the embedded application depends on the need and the platform used.
