High current consumtion after using NFC NRF52

VadimSavchuk

Hello. I have a problem. After using nfc, current consumtion still high. I found that I need use HAL_NFC_ENGINEERING_A_FTPAN_WORKAROUND macros. But when I specify this macros, nfc does not work. How to reset NFC module? I use Nrf52 separately. Not on BOARD_PCA10036 or BOARD_PCA10040. Help me please. This is last problem in my project.

    To check if BLE Nano v2 is effected by this errata or not, we need to know what IC revision that is used in BLE Nano v2.

    Could you read the FICR INFO.VARIANT register? What value do you get ?

    If you are using some printf/log function, you can easily print the value like this:

    printf("FICR INFO.VARIANT: %08X\n",NRF_FICR->INFO.VARIANT);

    Another important question is, when you measure the current consumption, how high is it? Do you have a number here?

    It could also be that you are affected by this ?
