NTagJavaSamleApp: NTAG424 not supported

dPritchard — Sat, 30 Sep 2023 23:26:23 GMT

When running the NTageJavaSampleApp, 3.0.1, with Identiv 3700F reader, I'm getting "Unsupported tag" on NTAG 424 DNA, when trying to read the NDEF data. The "NTAG Operation" button does not even react, neither show errors.

Is it possible the application does not support the 424 DNA family at all?

The error in the log for the NDEF read is:

Dear dPritchard,

As NTAG 424 DNA is NFC Forum Type4Tag, you need to select NDEF Application first and then perform ISOReadData command. On top Read Access right (e.g. 0x0E) to NDEF file needs to be granted.

Try after your GetVersion command, like this (interface APIs):

byte[] NTAG424DNA_NDEF_APP_NAME =
        {(byte) 0xD2, (byte) 0x76, 0x00, 0x00, (byte) 0x85, 0x01, 0x01};



intag424DNA.isoSelectApplicationByDFName(NTAG424DNA_NDEF_APP_NAME);
retData = intag424DNA.readData(02, 0x00, 0x00);
