title: send an array of bytes by NFC
body: <p>I want to communicate between an ARM and a Smartphone (I have an Xperia Sola and a Acer S500)
  (with my ARM I've a PN532)</p>
  
  <p>everywhere I've seen, people send NDEF messages to a tag or for beam anything... </p>
  
  <p>In my case I just want to send an array of Bytes. the goal of this project is to send a file to the arm, so I gonna send my file cut.</p>
  
  <p>for the moment my ARM read and write on DESFire tag's so i would user the isodep class because I see that we can send an array of bytes with this method : public byte[] transceive (byte[] data) </p>
  
  <p>can you help me to know what I'm needing to do ?</p>
  
  <p>Thx a lot</p>
