I am currently working on a school project that includes NFC communication to send posters (or URL) from PN532 (connected to a Raspberry Pi) to an Android phone.
I have been looking for a library where I can implement SNEP/NPP in order to send an NDEF message to an Android phone, like "libllcp" from "libnfc".
However, when I run the "snep-server" example from the library, all I can do is receive data from the phone, but not sending data to it while no response is given by the phone when I run the "snep-client" example (the phone vibrated but no data is received).
Since I am only familiar with C++, I want to know whether I can send NDEF message with "libllcp" alone or is there a C/C++ based library which I can implement SNEP/NPP.
How can I fix this problem?
