NFC type 4 tag implementation in SDK 11

[Bhavesh Shah]

Hello,

We have an old working product which is developed in nRF5 SDK v11.0.0. We want to add nfc type 4 tag part in our product. 

In SDK 11 there is only support for nfc type 2 tag only. 

Is is possible to take the part of NFC type 4 tag from SDK 16 and implement it in SDK 11?  Will there be any issues in doing that?

So far we know that NFC part is dependent on its library file (nfc_t4t_lib)and its source files (*.c and *.h).

There is a difference which we found between SDK 11 and SDK 16, and that is nrfx drivers part is added in newer SDK 16.  Is it possible to custom port those part also in older SDK 11

Have anybody tried this porting new SDK parts in old SDK?

This is not something I have tried to, you may check out the documentation:
https://infocenter.nordicsemi.com/topic/sdk_nrf5_v16.0.0/nfc_type4tag_dox.html

Seems it only need TIMER4 and that clock is enabled?

Thank you Kenneth for you replay. It works. We are able to port NFC part to sdk 11.

Now next part in our project is to use hardware crypto peripheral which is there in SDK 15-16 but not in SDK11 or not even in SDK 14. is there any points which we need to take care while using crypto hardware in SDK11
