Can't access MiFare4K tag in Emulator with signed Midlet which works on real device

[anand_misier]

Hi,

I have written a Midlet to access the Mifare4K tag and try to read block zero.
I have signed the Midlet. It works well on a real device (nokia 6212).


I have created a new Mifare4K tag in the Nokia 6212 Emulator. This is an image of the Nokia 6212 tag.
When i try to access the internal tag in the Emulator i get the error message that read is failed. This is the same signed with a certificate midlet.

Anybody who knows what could be a reason for this problem?

Regards,

Anand

On emulator try the unsigned midlet... emulators dont require signed midlets.

Hi,

Thank you for your response.

I did but no difference. It still refuses to read the internal tag.
I tried both with differnt default keys

{ (byte) 0x00, (byte) 0x00, (byte) 0x00, (byte) 0x00, (byte) 0x00,
(byte) 0x00 };

{ (byte) 0xff, (byte) 0xff, (byte) 0xff, (byte) 0xff, (byte) 0xff,
(byte) 0xff };

Do i need any keys to read from the internal tag?
