Hello,
I tried to parse the data on an NXP Mifare 4k, which was written by the ImageNdef-Example.
This is an example deliviered by the Nokia NFC-SDK for the mobile phone 6212.

I expect in the Block 1 of the tag the Capability Container (CC).
With CC0 = 0xE1 for NFC Forum defined data.
(Block 0 UID and other TAG-things)
The data in block 1 is written to:
0xC4 0x01 0x03 0xE1 0x03 0xE1 0x03 0xE1 0x03 0xE1 0x03 0xE1 0x00 0x00 0x00 0x00.

Is there another NDEF-Managment for the Mifare 4k?
I found a specifikation for the NXP Mifare Ultralight, which is descripted in the Type 2 Tag Operation document by the NFC-Forum.
