test on Mifare Classic with CR95HF

Hello,

I'm trying to communicate with a Mifare classic card but I can't.

I'm following the example described on the datasheet (page 60) and when it comes to auth, I'm sending the command:

0x04 0x09 0x60 0x00 0x04 0x00 0xd1 0x00 0x3d 0x00 0x18

But the answer is alway the same: 0x87 0x00

I've tried modifying the frame waiting values, but the error persists.

Any idea?

Thanks in advance!

Hello ELasa,

As mention in the datatsheet :

MIFARE and MIFARE

®

 Classic are trademark of NXP B.V. and are used under license.

CR95HF is able to manage the Parity Framing mode compatible with MIFARE

®

 classic requirements. However, access to Authenticated state must be support by an external secure host which embeds the MIFARE

®

  Classic library. So you have to check with the TAG provider specifications in order to manage the entire sequence and protocol which is not natively done by the CR95HF.  

Regards
