PN7462C/OM27462CDKP:Need help reading NDEF data from Android and iPhone for Access Control App

[YRK]

I somehow got the NfcrdlibEx3_NFCForum_mcux for the PN7462AU successfully and can read a physical NFC tag (NTAG215) and its NDEF data as below:

 NFC Forum Example: 

 Card detected and activated successfully 

Number of tags: 1 

Technology : Type A

Card : 1

UID  : 04 FA D5 57 BD 2A 81

SAK: 0x0

Type : Type 2 tag

NDEF detected...

NDEF length: 15

NDEF message:

[0000]  D1 01 0B 54 02 65 6E 30 30 31 31 31 31 31 31 00  |...T.en00111111.|

[0010]  00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00  |................|

[0020]  00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00  |................|

[0030]  00 00                                            |..              |

I programmed the physical NTAG215 with plain text of '00111111'.

Now, when i try to emulate a tag using my Android Phone using the "NXP Tools PRO" app which actually supports Tag emulation (at least NDEF payload emulation), this is the log (for the same plain text of '00111111'):

 Card detected and activated successfully 

Number of tags: 1 

Technology : Type A

Card : 1

UID  : 08 EF 94 5D

SAK: 0x20

Type : Type 4A tag

No NDEF content detected...

 Card detected and activated successfully 

Number of tags: 1 

Technology : Type A

Card : 1

UID  : 08 F0 49 8D

SAK: 0x20

Type : Type 4A tag

No NDEF content detected...

I am aware that the UID of the phone is gonna change with every transaction because of security reasons.

My application is to use either Android or iPhone for Access Control Application, where the NDEF payload in a NFC Application is gonna be used for Authentication (as the 1st step).

The ultimate goal is to use NFC passes stored in either Apple Wallet or Google Wallet as a means for Access Control using the embedded NDEF payload in those passes (don't know if it's possible with the kit and what is need to support this).

And I am aware that in order to use Apple Wallet or Google Wallet, the Apple VAS and Google SmartTap protocol needs to be implemented in the code.
Would anyone please be able to explain the process on getting any examples for integrating these protocols into our design?

I found this thread: Detecting-iOS-phone-using-PN7642 where @Fabian_R mentioned about contacting the distributor, but need more details, if possible on the process of integrating Apple VAS and Google SmartTap.

Can anyone please help with this application?

Thanks a lot in advance.

Regards,
Yash

Hi,YRK,

I have recently purchased PN7462 development board, Can you share me the application code which you have tried for NTAG215 , that will defintely help me to understand the NDEF communication.

Thank you,

Hello @YRK 

And please establish an NDA with NXP by going to  https://www.nxp.com/support/support:SUPPORTHOME and select "Request an NDA"

Hello @YRK 

Yes, you need to integrate the ECP into your system and PN7462 also supports ECP feature, which is development by Apple, so you need permission from Apple to use ECP in your design.
It is just that we cannot give details or the ECP enabled library to customer. The first have to get Apple approval!
Only after we got the approval from Apple that this customer is ECP approved, we are allowed to give the customer our ECP enabled NFC Reader Library and further ECP support. Therefore, if you want to implement the ECP feature on PN7462, the followings should be made:
1. Get approval from Apple for using ECP feature in your application.
2. Sign an NDA with NXP
3. Back to NXP to get ECP design resources.
