NFC Ultralite

[deepanrajanbara]

Hi,

We are testing NFC with Mifare UL card and the application we are using is provided by NXP .When testing Ultralite using NXP demo application we are not able to read any data or write data.But when we try to read Classic card we are able to read and write.I noticed that there is a parameter which is described in libnfc-nxp.conf i.e "MIFARE_READER_ENABLE" which is set as 0x01 for Mifare classic card.But what is the parameter to be set in order for us to read or write Ultralite card.Please Reply as soon as possible as am not getting support from anybody

Thank you,

Thank you This code seemed to format my ultralight card and now am able to read and write to my card.

But we have another Classic card which need to be formatted But the code changes only seemed to format ultralight cards.

[jeremygeslin]

Great to hear tat the Utralight issue is fixed now in your side.

Regarding MIFARE Classic, indeed the changes provided only impact Ultralight.

For deeper analysis, please provide logs same as before with Ultraligh. But pay attention that if the keys on the card have been previously changed the application won't be able to format the card (not knowing the keys used).

[deepanrajanbara]

Does this library support Desfire card ?

[jeremygeslin]

I confirm the current library does support MIFARE Classic and MIFARE DesFire cards ... but not the NDEF Formatting of such cards.

[deepanrajanbara]

Can you please check the log regarding the formating of Classic card and provide me update for the code

[jeremygeslin]

Please find attached updated demoApp formating MIFARE Classic code prior to the write NDEF operation.

Pay attention that formating can only success if card is in factory state (factory default keys).

[deepanrajanbara]

when we are formatting we are getting "Mifare Formating failed" error.

Even Our Desfire card is not able write/read we think it is same issue as that for formatting the card.Please check the log attached with respect to the desfire card.

Thank you,

All those MIFARE cards management is quite huge to be implemented. I would suggest you to use existing open source libfreefare for such application: GitHub - nfc-tools/libfreefare: A convenience API for NFC cards manipulations on top of libnfc. 

This libfreefare library runs on top of open source libnfc library. You can refer to the project I forked which includes support for the PN7120 via the Linux_libnfc-nci library: GitHub - jgeslin/libnfc: Platform independent Near Field Communication (NFC) library .

First of all the libnfc-nci must have been installed in the environment (sudo make install) and LD_LIBRARY_PATH environment must reflect the library installation patch (/usr/local/lib).

After cloning the jgeslin/libnfc repository run the following commands:

autoreconf -vis

./configure --prefix=/usr --sysconfdir=/etc --with-drivers=pn71xx

make

sudo make install

export LIBNFC_INTRUSIVE_SCAN=true

Pn7120 should be visible when running command:

nfc-scan-device -v

Then, after installing libfreefare, you shall be able to use related commands like:

mifare-desfire-format

mifare-classic-format

...

[deepanrajanbara]

But this libfreefare and libnfc opensource use USB to check with cards.we have cross-compiled  it for imx6 But when we execute the command we are getting

Do you know on  how to make it read through i2c

[jeremygeslin]

If properly configured, the libnfc will enumerate PN7120 through tthe libnfc-nci library.

Did you take the libnfc source from my forked project https://github.com/jgeslin/libnfc.git ? Because PN7120 support is not yet included in formal libnfc git repository.

Then what the result of the libnfc build with pn71xx driver option ?

autoreconf -vis

./configure --prefix=/usr --sysconfdir=/etc --with-drivers=pn71xx

make

sudo make install

export LIBNFC_INTRUSIVE_SCAN=true

[deepanrajanbara]

Now this application we have cross compiled and when "mifare-desfire-format" is given it is able to format the card but when we try to write using the demo app its  not able to write to my card

 NFC Tag Found

                Type :          'Type A'
                NFCID1 :        '04 43 5C C9 92 26 80 '
                NDEF Content : NO

        Not a MIFARE card

It gives the below message when we try to write content

[jeremygeslin]

Indeed the "mifare-desfire-format" tool is factory fromatting the DesFire card. To NDEF format it you shall use "mifare-desfire-create-ndef". Then later you can use nfcDemoApp to write any NDEF data in it.

[deepanrajanbara]

Thank you,Now it seemed to work with desfire card after formatting ndef

[deepanrajanbara]

Actualy for our Classic card the key is 0xFF for all.For this any changes is required ?

[jeremygeslin]

Please provide log related to MIFARE Classic formating failing case for deeper analysis.

[deepanrajanbara]

I have attached the log for classic card when the formatting fails

[jeremygeslin]

In the log are missing the NCI exchange (NxpNciX and NxpNciR) required for analysis.

You probably disabled it in libnfc-nxp.conf file (NXPLOG_NCIX_LOGLEVEL and NXPLOG_NCIR_LOGLEVEL parameters).

[deepanrajanbara]

Please find the log attached

[jeremygeslin]

In the log I can see that writing to the block 1 (sector 0) is failing. Please run the same and provide logs with attached updated demoApp which read first the sector 0 in order to understand why the write is failing.

[deepanrajanbara]

Please find the log attached

[jeremygeslin]

Please apply attached patch and run the same.
