I know that this lib isn't a universal solution, but it's a good basis, because it's not so large. I want to set the PN532 to the TgInitAsTarget mode, so that I'm able to emulate an tag and also to do p2p communciation. But first I'd like to emulate a card, what a Android smartphone could read. I found some C code at https://github.com/Seeed-Studio/PN532/blob/master/PN532/emulatetag.cpp But I'm not so well skilled in C. I would be very very grateful, if you could give me some input. Thanks Thanks for the response.

The library was a short research project and not designed as universal solution. Do you have example (C/C++) code for PN532. I could help with some input if possible. The implementation with spec only is not a problem but needs more time! We didn't try ISO14443-3. The library was a short research project and not designed as universal solution.

One question - have you already tried to emulate an ISO14443-3? I want to extend your java lib - but I'm not able to init the PN532 as a Target. Thanks! Hi!

But I didn't own different tags, so classic was my first choice. open-nfc is popular and should work, but I've no experience with embedded devices (yes, complex+) BTW. The eNFC project contains some test cases. You could start with some basic tests because ultralight isn't too different to classic. There is good documentation available: UL: http://www.nxp.com/documents/data_sheet/MF0ICU1.pdf, (http://www.nxp.com/documents/application_note/AN1303.pdf) or Classic 1K: http://www.nxp.com/documents/data_sheet/MF1S503x.pdf It took about 1 day to implement current eNFC functionality (without refactoring), so it shouldn't be more than some hours to change it to support ultralight. :) Yes, the lib is small and the complexity of all other solutions was the reason for developing a small one.

No - the libary found the card but doen't get the ACK frame. I know that there are libs - but I use a beaglebone and want to use java and other libs are really big and complex, or do you have a recommendable other lib? Thanks for your fast reply!

Did writing work? The library is not complete because it was designed for one use-case. There are complete NFC libs available!
