How can I find the NFC Card Number in the log of NCI commnucation?

[andy_kim]

Hello,

We have a PN7150 EVK(OM5578) with Arduino UDOO Neo.

We imported NXP-NCI_iMXRT1060_example on it and tested NCI communication of it.

When we attached a Transportation Card to NFC Antenna of PN7150 EVK after "WAITING FOR DEVICE DISCOVERY" message, we got a log below.

However, we are not able to figure out the number of the Transportation Card in the log.

Could you let me know how to check it?

Hi @andy_kim ,

The NFC ID is 08 b8 0c 64 from your log.

Hope that helps,

Have a great day,
Kan

Dear Kan,

Thanks for your reply.

How "08 b8 0c 64" of NFC ID comes out from the log?

It shows "8 f c4 87" of NFC ID in the log below.

- POLL MODE: Remote T4T card activated
        SENS_RES = 0x4 0x0
        NFCID = 8 f c4 87
        SEL_RES = 0x20

In addition,

I think that is NFC ID, not Card Number of Transformation Card.

Could you check again how we can get the Card Number of Transformation Card in the log?

Is it available to figure out the Card Number of it through NCI communication?

Thank you,

Best regards,

Andy

Hi @andy_kim ,

I got this info from the following log:

NCI << 61 05 1d 01 02 04 00 ff 01 09 04 00 04 08 b8 0c 64 01 20 00 00 00 09 08 78 00 c2 02 00 00 ...

Have a great day,

Dear Kan,

Thanks for your prompt reply.

Could you let me know which document I should refer to for figuring out the meaning the log of NCI communication? 

I'd like to refer to the document if it is in NXP site.

Thank you.

Best regards,

Andy

Hi @andy_kim ,

You have to refer to the NCI spec from https://nfc-forum.org/our-work/specification-releases/specifications/#specs .

Have a great day,

Dear Kan,

Thank you for your comment.

Hi @andy_kim ,

Yes, it is NFC ID, which I can only figure out from your log. I didn't see any Card Number info from there. 

Have a great day,
Kan
