Sorry, we don't have anything more than what is part of the SDK already. If you need further information I assume you need to check the datasheet of the NFC reader and modify as required.

Hello,

You are using a very old nRF5 SDK, I would at least recommend using the latest minor release of SDKv15, which is 15.3. But you should consider updating to nRF Connect SDK moving forward.

I assume you have followed carefully the description:
https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v15.3.0/nfc_adafruit_with_tag_parser.html

My best suggestion then is to add a logic analyzer to the TWI pins in question and see if you observe any data:
