cannot read type4tag ndef record

Asked by Derk Tegeler

When touching a type 4 tag (Yubikey NEO), the ndef record is 'None', whilst it works on a android phone.

The examples/tagtool.py app reports an exception: 'capability container not found'

Is this a bug or a limitation?

code:
In [1]: def connected(tag):
    print tag,tag.ndef
   ...:

In [2]: import nfc

In [3]: c=nfc.ContactlessFrontend('usb' )

In [4]: c.connect(rdwr={'on-connect': connected})
Type4Tag ATQ=4400 SAK=28 UID=043d1d4a0e3580 ATS=1178f7b102597562696b65794e454f7233 None
Out[4]: <nfc.tag.tt4.Type4Tag at 0x24a0210>

In [5]: print c
SCM Micro SCL3711-NFC&RW on usb:002:025

Your tag may just not be prepared for NDEF. Run "examples/tagtool.py -d nfc.tag" to see if the NDEF File on the tag could be opened.

Can you help with this problem?
