I have no problems using RFID cards what so ever. I can read them and write on them. However, I have to use an Android Phone as a tag. For that I have been suggested 2 things. Either using a tag emulator to use phone as a basic tag, which is very hard, or use the p2p mode.
My problem is that have found a library called nfcpy which makes everything very easy in terms of p2p communication but it does not support PN512(it support 532 and 522).
Is there any library or kind of support to use p2p mode on this device?
