PN532 card emulation mode issue

juhun — Tue, 12 Sep 2023 06:07:09 GMT

Hello.

There is an issue in the process of emulating PN532 with the card using libnfc.
I am testing card emulation with the libnfc/utils/nfc-emulate-forum-tag4.c code on libnfc github.
After running NFC Tools on iPhone and Galaxy S20, I was able to confirm that when I tagged the emulated card, the tag information was output as Mifare plus, ISO 14443-4 and the NDEF message was delivered well.
However, when testing with the Galaxy S10, the tag information was output as JIS 6319-4, Unknown Felica and no data was received.
How can I resolve issues in my s10 environment?

Hello, my name is Fabian, I've been assigned to support your case.

Thank you for your interest in our products.

We strongly recommend to please take a look at PN7160, which is an NCI-driven Controller. As you are able to see on the PN532 site, it isn't recommended for new designs, and, it is possible that you may have some issues with the supply in the near future.
