Solution
In P2P mode, two NFC reader-mode devices communicate with one another, both acting as a reader and neither as a card-type device. Each device will turn on its own 13.56 MHz field and communicate via amplitude shift-keying (ASK) as if the other device were a card. The P2P protocol is based on the
ISO 18092 NFC standard.
This means that in terms of analog conformance, as P2P device can be tested against the
NFC Forum Analog Test Suite as a reader mode device.
For digital conformance, we can use the following cases from the
NFC Forum Digital Test Suite:
- Group 2.9 - Peer2Peer with NFC-A
- Group 2.10 - Peer2Peer with NFC-F
- Group 3.7 - Peer2Peer with NFC-A
- Group 3.8 - Peer2Peer with NFC-F
