NfcrdlibEx8_HCE_T4T example

nddona — Thu, 28 May 2026 05:01:48 GMT

We have a custom Linux platform where we have successfully made the PN5190 to work as a card reader for years.

Now we want to try out to make it work as a type 4A tag as in example "NfcrdlibEx8_HCE_T4T". We have tried to use the example with the reader library version 7.14.00 but we're getting the same results as reported in the thread: https://community.nxp.com/t5/NFC/HCE-T4T-Example-not-working-with-NXP-NFC-Library-v07-08-00-in/td-p/1686764

When Android (Samsung S23 ultra) is tapped with NXP "TagInfo" App, it's getting an invalid RATS. Rx buffer receives data starting with 0x11 0xD4 ... etc.

[phacDiscLoop_Sw_Run] Starting Listen Mode
[T4TCardEmulation] Card Activated in Listen mode...
[phpalI14443p4mC_Sw_Activate] RATS: 11 D4 00 8C 26 82 9B FA 12 01 DF 84 5B 00 00 00 30
[phpalI14443p4mC_Sw_Activate] Invalid RATS received...

Is it because the phone is trying to talk in NFC-DEP (P2P Mode / SNEP)?

Appreciate any help to resolve this issue.

Thanks!

This issue is solved by disabling some macros and updating the SAK to correct value 0x20.
