NDEF NOT DETECTED (ndefPollerNdefDetect returns 5)

HI! I have that nfc tag: and whet i tried to read data from it st32r3916 + lib returns that:

NDEF NOT DETECTED (ndefPollerNdefDetect returns 5)

but tag was detected and i could read Serial Number :

1. Tap a tag to read its content

ISO14443A/NFC-A card found. UID: 04EEB69AE64C80

NDEF NOT DETECTED (ndefPollerNdefDetect returns 4)

Operation completed

Tag can be removed from the field

So is it possible to read data from that tag with st25r3916?

And what's wrong with current setup?

Thanks!

Best regards,

Matvei

Hi Matvei,

our demos can only read an NDEF if there is an NDEF already written on the tag. So I think there is simply no NDEF message written onto it.

For further discussion about NDEF you may just look at this recent thread: xnucleonfc06a1-doesnt-read-and-write-any-tag-ndef-not-detected-error.

Feel free to try to change the demo to dump the complete memory, etc.
