how to put nfc reader in p2p mode Android-powered devices with NFC simultaneously support three main modes of operation: Reader/writer mode, allowing the NFC device to read and/or write passive NFC tags and stickers. P2P mode, allowing the NFC device to exchange data with other NFC peers; this operation mode is used by Android Beam. Click LOAD TAG to load Amiibo data of the villager you want.; Click SAVE TAG to save chosen Amiibo data on to the tag of your choice. *Be aware that the NFC tags are NOT re-writable in this case, as official Nintendo Amiibos also lock in .

As far as I understand with the latest Android SDK it is possible for the phone to act as a 'Tag' to be read by a NFC reader. I would like to implement the following scenario: Phone gets placed next to an NFC reader. Android-powered devices with NFC simultaneously support three main modes of .

Android-powered devices with NFC simultaneously support three main modes of operation: Reader/writer mode, allowing the NFC device to read and/or write passive NFC tags and stickers. P2P mode, allowing the NFC device to exchange data with other NFC peers; this operation mode is used by Android Beam. Tag Mode: the NFC device supplies data to a reader as requested. Peer To Peer (P2P): the NFC device switches back and forth between reader and tag mode in order to allow free flowing data back and forth between the devices.

With NFC two active devices would communicate with each other using peer-to-peer mode. Reader/writer mode is for communication with NFC tags/smartcards only. So with Android, if both devices should actively communicate, you would have to stick to Android Beam. I want to know how to switch ST25R3911B from reader/writer mode to the P2P mode? Are there any register to config the working mode? In the datasheet, I find there is a register called "Operation control register" which can control the rx and tx enable.This post explores the three modes of NFC: Tag Reader/Writer, Card Emulation and Peer to Peer (P2P) mode. Part 1 of this post focuses on the security of Tag Reader/Writer mode, Part 2 on Card Emulation mode and Part 3 on P2P mode. To download the library, please refer to NFC Reader Library|NXP. For the MCU, I recommend LPC1769, which is also used on OM25180. Please refer to https://www.nxp.com/docs/en/application-note/AN11744.pdf for more details.

I use the NXP NFC Libary with a CLRC663 frontend. I can act as client and send a NDEF Message to an Android phone with put. I can act as server and receive a NDEF message from an Android phone.

There is an active P2P mode (not recommended by NFC Forum) and a passive one (recommended by NFC Forum) where the passive device works like a smartcard (card emulation mode). I also know that an NFC reader device does usually the following steps: Field on. Check for a card or a P2P passive device. Firstly, configure the host-based card emulation mode like described in one of my previous blog posts. Secondly, create an Activity that will enable the new Reader-Mode in Android 4.4 and create a reader callback that will handle the discovered tag as an IsoDep tag.
