Can it be this errata? http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.nrf52840.Rev1.errata/dita/errata/nRF52840/Rev1/latest/anomaly_840_190.html?cp=2_0_1_0_1_21

This has been fixed in SDK 15.2.0 but it requires you to include the nfc_fixes.h file. Have you included this in your project?

Hi, sorry for not answering you. Have you figured out what is wrong? It's hard to tell what is wrong. Can you please post your project so I try it out here?

Hi, which version of the SDK are you using? Also, please provide the version of the nRF52840 DK and the chip version/build code written on the chip. Can you post the content of TAGHEADER registers in FICR? You can get it with this command: nrfjprog --memrd 0x10000450 --n 16

Thanks
