    35   * Uses the low-level Symbian interfaces for doing a Bluetooth device discovery,

    36   * allowing for more flexibility with the user interface. Results of the device discovery and

    37   * SDP request are stored in private variables until extracted by CRsBTDiscoverEngine

    38   * which owns the only instance of this class, and directs the asynchronous functionality.
