Help to decode xbee S2 API packet
You have a bunch of "stuff", followed by the data you sent, followed finally by another bunch of "stuff".  I don't know what the "stuff" is, but I can see and decode your data easily enough.

I suspect you transmitted the data using .println(...).  That will send an ASCII representation of the data.

So to take the line: -196.88&lt;CR&gt;&lt;LF&gt;, if we find the ASCII values and represent them as hexadecimal we have:


  2D,31,39,36,2E,38,38,D,A


Which I am sure you can find in one of those lines - maybe this one:


  0,15,90,0,13,A2,0,40,C1,A8,2E,98,8D,1,2D,31,39,36,2E,38,38,D,A,3B


So you have 14 bytes defining something interesting about the packet (I'm sure Google can tell you what - source and destination maybe, probably a packet length too), then your data, and finally what looks like it's probably a checksum.
