Thanks for the clarification!! I understood nrf52832 only supports Type 2 tag and not fully support Tag type 4 ( As it not compliance by standard ISO14443-B.)

The nRF52832 NFCT peripheral is a NFC-A listening device. It support both Type 2 Tag and Type 4 Tag.

Hi Jørgen,

Thanks for the prompt answer! As per my understanding, nrf52832 SoC supports NFCT type - 2. So i prefer to go with self implementation to write tag -2 rather to type - 4 tag, suggested link in your comment help me in implementation.

I have question, why SDK provides Type- 4 tag example for nrf52832 as hardware is not supported for that?

Hi,

I'm not aware of any sample code with working NFC type 2 tag with write capability. The hardware support it, so it should be possible to add this yourself if needed. There is a thread about this here.

It has been discussed if support for type 2 tag write should be added for backwards compatibility with existing systems, but I cannot comment on if or when this will be added.

For now, your alternatives are to switch to type 4 tag, or add the write functionality yourself.

Best regards,

Jørgen
