      NFC tag: NFC Forum type 1 96 bytes.
      Qt app: nfceditor

      ndefeditor application in Nokia C7 with Symbian Anna writes junk bytes after the NDEF message when NFC Forum type 1 tags are used. As an example I wrote the NDEF message containing the URL http://www.nokia.com with ndef editor and this is the HEX dump from the tag:

      E1,10,0E,00,03,0E,D1,01,
      0A,55,01,6E,6F,6B,69,61,
      2E,63,6F,6D,*32,32,32,32,
      32,32,32,32,32,32,51,01,
      07,54,02,65,6E,43,61,6C,
      6C,*00,00,00,00,00,00,00,
      00,00,00,00,00,00,00,00,
      00,00,00,00,00,00,00,00,
      00,00,00,00,00,00,00,00,
      00,00,00,00,00,00,00,00,
      00,00,00,00,00,00,00,00,
      00,00,00,00,00,00,00,00,
      55,55,AA,AA,00,00,00,00,
      01,60,00,00,00,00,00,00,

      When the expected HEX dump is:

      E1,10,0E,00,03,0E,D1,01,
      0A,55,01,6E,6F,6B,69,61,
      2E,63,6F,6D,FE,00,00,00,
      00,00,00,00,00,00,00,00,
      00,00,00,00,00,00,00,00,
      00,00,00,00,00,00,00,00,
      00,00,00,00,00,00,00,00,
      00,00,00,00,00,00,00,00,
      00,00,00,00,00,00,00,00,
      00,00,00,00,00,00,00,00,
      00,00,00,00,00,00,00,00,
      00,00,00,00,00,00,00,00,
      55,55,AA,AA,00,00,00,00,
      01,60,00,00,00,00,00,00,

      Also note that in ndefeditor is not writing the TLV Terminator FE at the end of the NDEF message. So far I have not seen that this creates any misbehavior in Symbian sw, i.e.: symbian sw is able to parse the NDEF message correctly despite of the extra junk bytes added at the end of the NDEF message.
