Which SDK version are you using and do you package NFC libs with ur jar file ?

Thanks Geri-m I missed the workshop!

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).

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...

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

You have :
NFC Forum Ext Type
urn:nfc:ext:nokia.com:bt
Bluetooth record (for printing/image frame)

Hello,

I need technical support in order to set my own CardManager keys inside the smartcard of the NOKIA 6131 NFC (GlobalPlatform 2.1.1).
First think to know is that my secure element has been...

Guys, do you know how to reset permenant lock out of the Secure Element in case we did 10 incorrect tries :(

So what is the solution to implement a web service client on NOKIA 6131 NFC ?

You can store records on Elementary File, Dedicated File, ... in the internal Secure Card.
See chapter 5 here: http://java.sun.com/products/javacard/AppletDevelopersGuide.html

For backward...

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...

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...

I am not sure about SE unique ID. But MIFARE 4K card emulated by the phone has a unique NFC ID (stored Block 0 Sector 0 Manufacturer Block).

I think it's Java Card 2.2.1

Many thanks samuuh :)

Try to use JCOP Tools from IBM (I think support is now delegated to NXP).
Then see http://java.sun.com/products/javacard/AppletDevelopersGuide.html

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...

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...

Hi !
Is there a way to change Mifare SAK of the internal MIFARE 4K card emulated by the Nokia 6131 NFC ?

Hi Douglas,

From what I understand, this is the right way to do. Secure Element of NOKIA 6131 is a SmartCard / JavaCard and you can upload your Applet (thanks to JCOP / Pegoda Reader) on unlocked...

Your welcome ;)

As far as I know, methods are the same.

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

and
...

Let's add this info to WIKI :) thanks for clarification !

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.

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...

Good job Raluca !
Other code examples have already been posted by users. Maybe you can add them to the WIKI ? It would be great to have code samples for each NFC functionality.
