NFC P2P in I2C

Asked by laura on 2016-01-04

We would like to transfert data in both ways through NFC P2P with a smartphone (Android Beam). Right now, we are using a NXP PN532 module, in I2C (I2C is mandatory for the project, as we will be short on RS232 and SPI is more complex). We are not finding a complete out-of-the box solution, as Arduino and libNFC supports seem to be incomplete for P2P testing, and nfcpy is not working with I2C (and is in Python). Do you know were we could find something to help us, like a driver, a library, a source code using libNFC on Linux, even a code on another RTOS (mbed, FreeRTOS, Contiki...) which implements a successful NFC P2P protocol ?

There are NFC drivers in the Linux kernel, maybe one of those supports I2C. But I have no further experience with them.

Can you help with this problem?
