I'm trying to comunicate in P2P passive mode, a Nokia 6131 NFC with a NFC/MIFARE PLUG AND PLAY reader Arygon.
If I configure the reader as a target and the phone as a initiator, so there is no problem. The comunication is right and the phone recives datas. BUT if I configure the READER as a INITIATOR and the PHONE as a TARGET, so the phone shows an ERROR "Tag unusabled" just when the reader starts to send datas.

If someone has any idea why this happend, please reply me.

Thank you very much in advanced.
