Always use nfc_initiator_transceive_bytes(). If you where using advanced features and already relying on nfc_initiator_transceive_bytes(), then your code has to be updated to unset the NDO_EASY_FRAMING option. See an example of such a change in the libfreefare's repository: http://code.google.com/p/nfc-tools/source/detail?r=566 Updates issue 106 Status: Feedback Romuald: I am not sure about the option enum values. I took 0x02 thinking it would not hurt but am not really sure about that because I can see many 'holes' in the sequence.
