undefined symbol CHIP_NFC_COMMISSIONING

[lboue]

Hello,

 

I would like to know how to disable the NFC function with nRF SDK 3.1.0

I would build the Matter thermostat sample. I tried this: `CONFIG_CHIP_NFC_COMMISSIONING=n` but I am getting an error:

C:/GitHub/nRF_matter_thermostat/prj_release.conf:50: warning: attempt to assign the value 'n' to the undefined symbol CHIP_NFC_COMMISSIONING

Could you help me?

Hello,

What HW are you using? If you are using the DK, note that you also need to move some 0R resistors so that the gpios are actually routed out to the pin headers. Please see this:

https://docs.nordicsemi.com/bundle/ug_nrf54l15_dk/page/UG/nRF54L15_DK/hw_desription/nfc_if.html#d18e103

There you will also see that you need to use the Kconfig:

CONFIG_NFCT_PINS_AS_GPIOS=y

and not the CONFIG_CHIP_NFC_COMMISIONING=n.

Not sure where you found that last one. I can't seem to find it in the NCS v3.1.0 SDK

Best regards,

Edvin

I had to edit the boards\xiao_nrf54l15_nrf54l15_cpuapp.overlay file in my project to add this:

&nfct {

               status = "okay";

};

[Edvin]

Do you mean that you removed this, or added it?

I believe if you want to use these pins as normal GPIOs, you need to set it to status="disabled"; ?

Did you also use this in prj.conf?

CONFIG_NFCT_PINS_AS_GPIOS=y

Best regards,

Edvin
