Thank you very much i got the point on reading bytes issue. But i got one more question. Sorry for my lack of programming knowledge. How can I interprete binary data that i have previously converted from float data, to float data again on arduino. Suppose that ? have read 32 bit data. How could I convert to float again. :). I mean how to realize Float.intBitsToFloat code on Arduino or other algorithm which is identical. You know that this code is working on Processing, Java, etc.. languages. I really appreciate your efforts. Thanks alot.
