Peer-to-peer (P2P) is one of the three modes supported by the TRF7970A. The Near Field Communication (NFC) market is emerging into multiple fields including Medical, Consumer, Retail, Industrial, Automotive, and Smart Grid. Peer-to-peer (P2P) is very common in these fields, because it allows for a wireless virtual channel to be created between two devices. This application report describes two NFC technologies, the NFC-F and NFC-A protocols, which are used to initiate the communication for peer-to-peer active or passive modes. Furthermore, this application report explains how to implement an application using active or passive P2P communication, supporting baud rates of 106 kbps, 212 kbps and 424 kbps on the TRF7970A transceiver.
