NFC data exchange

[Nikhilesh]

Hello! We are trying to transfer the data between two nRF52840 development kits through NFC. Is doing so possible without using any other reader hardware? If not, then we also have a PN532 NFC reader with us but we are unable to find how to use it with nRF52840 DK. As mentioned in the examples section of nRF5_SDK_15.0.0_a53641a, the polling device is given as nRf52832 DK interfaced with PN532 and the tag device is nRf52840 DK. Can nRF52840 DK along with PN532 be used as polling device as well? If so, can you provide us with the interfacing of PN532 with nRF52840 DK. Can a 3rd party platform such as Arduino interfaced with PN532 be used instead of nRF52840 DK at polling side?  

Waiting for you reply. 

Thanks and Regards,

Hi

A reader is necessary, the nRF52840 should work with the Adafruit PN532 NFC reader by replacing the pin configurations for irq and reset in the config file so that it fits the nRF52840. 

Current SDK file:

// <o> PN532_IRQ 

#ifndef PN532_IRQ

#define PN532_IRQ 13

#endif

 

// <o> PN532_RESET 

#ifndef PN532_RESET

#define PN532_RESET 14

#endif

After changes: 

 

// <o> PN532_IRQ 

#ifndef PN532_IRQ

#define PN532_IRQ 35

#endif

 

// <o> PN532_RESET 

#ifndef PN532_RESET

#define PN532_RESET 36

#endif
