Parsing raw data received from bluetooth HDP device

Question

I am trying to read data from an Omron 708-BT Blood Pressure Monitor which is certified by the continua health alliance. I am following this example of a Bluetooth HDP App. I am

@ Jieqin - great that you got it too :)

paste this in your reading thread under the block of

else if (data[0] == (byte)0xE7){
Log.i(TAG, "E7");
//work for legacy device...
if (data[18] == (byte) 0x0d && data[19] == (byte) 0x1d)  //fixed report

to parse your agents answer - and if it works, please rate my hints :)

else if (data[18] == (byte) 0x0d && data[19] == (byte) 0x1f)  //mp var report
                        {
