NFC reader with nRF9160?

[Brian]

Hello,

Curious if any NFC reader applications have been built with nRF9160?

We’ve just installed SDK v1.4.1.   We noticed there’s a nfc_tag_reader here: 
/opt/nordic/ncs/v1.4.1/nrf/samples/nfc

I noticed all the board overlay files were for nRF52x.   Is it possible to use that example with nRF9160?   Would it just be a matter of creating a new board overlay?   Or are we up against any other challenges?

Also, this nfc_tag_reader appears to be for the ST25R3911B.  

Awhile back wasn’t the PN532 supported?
https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v15.3.0/nfc_adafruit_with_tag_parser.html

Where did the the Adafruit Tag Reader example go?  Is it no longer included/supported?   What would be involved in porting this code over to the nRF9160?

Thanks,
Brian

Hi, Brian!

I don't know of any existing samples or projects using NFC with the nRF9160. However, I do not see any reason why the tag reader sample shouldn't work with the nRF9160 if you provide a proper board overlay. You must also add "nrf9160dk_nrf9160ns" under supported boards in the CMakeLists.txt file. 

The Adafruit Tag Reader example is at this time only supported in the nRF5 SDK and not the nRF Connect SDK. As the two SDKs are fundamentally different there isn't any straightforward way to port the code, but it could be possible using the nRF drivers. I would recommend sticking to the ST25R3911B, though.

PS: The Holiday season is upon us, which will leave the Nordic support team understaffed until January 4th, 2021. This means that delayed replies will occur during this time. Sorry about the inconvenience and happy Holidays!

Best regards,
