    Re: doubts about sector trailer access

    Connect to HTTPS and retrieve key A & key B from there. MIDlet is ur proxy.
    Or try to access MIFARE container directly from ur Applet (maybe with ExtSystem lib).
  4. Re: How to get secure-element keys of 6131 (without using unlocking midlet)

    You can unlock your SE and then put ur own keyset but yeah chain of trust has been broken blblblbl.
    It's better to do this only for development purpose.

    Only way is to ask Venyon, Cassis or other...

    Re: Bluetooth pairing

    I am quite sure "encoded bluetooth address as URI NDEF message" is not supported on 6131nfc.

  10. Re: 6131 NFC as a means to emulate ISO14443 cards in software

    Some readers support P2P as a top level protocol over NFC. I know PN531 does it but never tested it with Nokia 6131. Search for NFCIP-1 readers and maybe you will be able to connect your Midlet to a...
  11. Re: Detecting the Secure Element of the 6131 with another 6131

    NFC is magnetic field induction... maybe we found a real problem here. Phones (with tag detection ON) are on constant polling. Frequency band 13,56 Mhz could be altered ?

    We experience the same...

    Try to use JCOP Tools from IBM (I think support is now delegated to NXP).

    Re: Mifare Access Bits Tool

    Concerning Sector Trailer Access Bits, it is coded on 4 Bytes but I don't know about Byte number 9... I assume this is a kind of "check byte".
    Byte 6, 7, 8 have redundancy check (C1 C2 C3).
    Your...
  17. Re: Wrong data to internal 4k on block 3 of one of sector

    Bad access bits will lock your MIFARE card for ever.
    See MIFARE NXP documentation and make some testing on cheap cards before doing this on the MIFARE card emulated by 6131.

    Well... I am not sure...

    Re: 'Applet' or 'SecureCard'?

    As far as I know, methods are the same.

    String uri = System.getProperty("internal.se.url");
    ISO14443Connection conn = (ISO14443Connection) Connector.open(uri);

  23. Re: Nokia 6131 NFC (JSR 257) reader phone communication

    Good news if P2P works with this reader !
    I'll try with mine. SDK language is C and ask NXP for a PN531. Can't tell you more, sorry.

    Re: Is the UnlockMidlet available???

    25 euros to unlock a SE :)
    Anyway thanks ToP Tunniste! This is the only way for the moment (or you can't upload your javacard applet without 3DES keys).

    I hope the unlock MIDlet will be available...
