* getAddress() : Gets the MAC Address of the device
* getAdRecordStore(): Gives access to a device's Ad Records
* getDevice(): Gives access to the standard BluetoothDevice object
* getFirstRssi(): Retrieves the RSSI value which was used when the object was created
* getFirstTimestamp() : Retrieves the timestamp (in millis) which was used when the object was created
* getRssi() : Gets the current RSSI measurement (see note below).
* getScanRecord() : Retrieves the RAW scan record array
* getTimestamp() : Gets the timestamp of the last RSSI measurement
* getRunningAverageRssi() : Retrieves the internally calculated running average RSSI value (see note below).
