How to read tag data with CL663?

xiaominlu — Thu, 07 Dec 2017 16:19:07 GMT

Hi, I have evaluation board OM26630FDKM.

I followed the quick start guide and got the examples for CL663 in MCUXpresso IDE.

I am using project NfcrdlibEx1_BasicDiscoveryLoop as a starting point.

Information like the following is displayed:

Card detected and activated successfully...

Technology : Type A
Card: 1
UID : 04 7D 5B D2 9C 39 80
SAK : 0x00
Type: Type 2 Tag

But how to actually read the data stored in different tags?

You can see the NfcrdlibEx9_NTagI2C

I2C is not a wireless way to transfer data between reader and tag, I think what he want to know may be a wireless way.

HELLO jimmychan，

May I ask you a question about how can I shoud use clrc663 to read 14443a tag (m24sr64) by a wireless way?

Now,I can read and write MIFARE tag succesful, but can't do with 14443A tag?

This do sucessful:

status = phpalI14443p3a_ActivateCard(&I14443p3a, NULL, 0x00, bUid, &bLength, bSak, &bMoreCardsAvailable);

This failed:

PH_CHECK_SUCCESS_FCT(status, phKeyStore_SetKey(&Rc663keyStore, 0, 0,PH_KEYSTORE_KEY_TYPE_AES128, &Key[0], 0)); this function return 0x201.

And I find that PH_KEYSTORE_KEY_TYPE_AES128 is not supported by this software lib, in that function the case of "PH_KEYSTORE_KEY_TYPE_AES128" is EMPTY!

Finally, may I ask if the clrc663 can read/write with 14443a tag produced by other company?

And, wether the software lib is complete to support to read/write with 14443a tag?

Tanks a lot,

have a nice day!

We have an example of Discovery Loop. You may take this for reference.

Hi, jimmychan:

I have read this example,this ex can only find which type the tag is. And then, what shoud I do to read/write data to the type of 14443a tag.

Thanks a lot,and look forward to your reply.
