Hello,
im trying out some new nexus s nfc functionality. since mifare
emulation is not (so far?) available for this device (or just
software?) im playing with proximity cards.
basically, i have a mifare desfire ev1 chip but for some reason i
cannot communicate it using NfcA.transcieve - im gettin IOException
with null getMessage().
Below is found the code i use. I can get valid id and techlist from
the tag. This code uses its own thread as well.
try {
Tag tag =
intent.getParcelableExtra(NfcAdapter.EXTRA_TAG);
txtTagId.setText(Tools.getHexString(tag.getId()));
txtTagTech.setText(Tools.join(", ", tag.getTechList()));
NfcA T = NfcA.get(tag);
T.connect();
final byte[] APDU_getVersion = new byte[] { 0x60 };
byte[] response = T.transceive(APDU_getVersion);
T.close();
// notifyAll();
} catch (Exception e) {
Tools.DisplayException(e, ctx);
} finally {
}
Do you suggest any changes to the code?
