Reading NDEF-Message using PN532

Hi Martin,

I'm afraid I don't personally, but maybe looking at another library would help. For example Adafruit have a library, and if you're reading mifare (example at https://github.com/adafruit/Adafruit-PN532/blob/master/examples/readMifare/readMifare.ino) they seem to authenticate and then read, which both seem to be done with PN532_COMMAND_INDATAEXCHANGE:

• auth https://github.com/adafruit/Adafruit-PN532/blob/master/Adafruit_PN532.cpp#L868
  
• read https://github.com/adafruit/Adafruit-PN532/blob/master/Adafruit_PN532.cpp#L936
