Unreadable data received from bluetooth device

Question

I am trying to receive data from the finger oximeter over bluetooth. Connection works and i receive data in byte[] format, then i convert byte array to string format using UTF-8 encoding and result im getting is in this format:

Ba�JBa�OBa�TBa�W Ba�Z Ba�\ Ba�] Ba�]Ba�]Ba�] Ba�\ Ba�[ Ba�Z Ba�X Ba�W Ba�VBa�UBa�TBa�SBa�RBa�QBa�QBa�PBa�PBa�PBa�OBa�OBa�O@a�O@a�O@a�O@a�N@a�N@a�N@a�M@aa�B

And here is my code:

 if(b == delimiter)
 {
   byte[] encodedBytes = new byte[readBufferPosition];
   System.arraycopy(readBuffer, 0, encodedBytes, 0, encodedBytes.length);
   final String data = new String(encodedBytes, "UTF-8");
   readBufferPosition = 0;

  handler.post(new Runnable()
  {
      public void run()
      {
         Log.v("Test",data);
      }
  });
 }

What should i do to receive a readable data for displaying?

Use this constructor of String class:

String dataReceived = new String(mbyteArr, "US-ASCII");

You should, however be sure of the encoding name. My examples used "US-ASCII" and "UTF-8", the two most common encoding standards. May be you need to check the standard with the gadget's documentation.
