/**
 * This handler is specalised for decoding my polar hart rate monitor and get the data from it
 * Data format is something like this
 * 
 * 
 *   Polar Bluetooth Wearlink packet example;
 *   Hdr Len Chk Seq Status HeartRate RRInterval_16-bits
 *    FE  08  F7  06   F1      48          03 64
 *   where; 
 *      Hdr always = 254 (0xFE), 
 *      Chk = 255 - Len
 *      Seq range 0 to 15
 *      Status = Upper nibble may be battery voltage
 *               bit 0 is Beat Detection flag.
