Any plans to add Write capability to the NFC library?

[CurtisHx]

Are there any plans to add write capabilities to the NFC driver? The hardware supports it, but the library provided by Nordic does not (as far as I know). Are there any plans to add write support to the NFC library? Or do we just need to pony up the $$$$ to the NFC Forum for the spec(s)?

And if we do just need to buy the spec(s) which one(s) would we need to implement read/write capability on the NFC module?

Hi,

As most common use-cases can be achieved using NFC tag read, write functionality have not been implemented yet. Unfortunately, I cannot say anything about if or when this will be added to the NFC library.

The harware supports it, like you say, so it's possible to implement write functionality yourself. Check out this post from @thln. There are also some links in the comment that might be usefull.

Best regards,

Jørgen

I guess updated NFC libraries with write functionality will be released sometime, but I cannot guarantee this. An alternative if you do not want to add write functionality to the NFC library yourself, can be to use Wake on NFC to wakeup from sleep to turn on the radio for receiveing the code. It will probably consume a bit more current than write to NFC, but it should not affect the battery life that much. If you add DFU to your design you can also update the software to support NFC write in the future if updated libraries are released.
