Trying to use CLRC663 to read and write UID and data over desfire

mohamed_elsabagh — Mon, 09 Aug 2021 14:01:09 GMT

Hello, We are working on a project where we are using nrf52 MCU as host controller with CLRC663 reader. Until now we have been able to get UID from mifare classic tags, and read/write on different sectors/blocks. Now we need to start supporting Desfire EV2/3, but I can't find any usable codes or low level steps to:

1. Get the UID from a tag

2. Read/Write Customer user data to the tag.

Can anyone please help with this, thanks and BR.

Hello,

The related code is NDA. So you need an NDA to gain access to that documentation. If you has NDA. Please refer to the attachment how to find the document on Docstore.

Have a nice day.

So In order just to read UID of a desfire EV2/EV3 using nxp chip CLRC663 this needs NDA?

And to start writing and reading custom application data on desfire, I need this as well? so how can I get an NDA in this case?

Hi Fang Fang

Mohammed is a developer inthe eLocker team, we have already signed the NDA but I cannot locate the SW375617 file on our account, I think we need a higher access level to be able to download this file, please can you allow us access?

Thanks

Jacob

Hello,

In case you are not able to find it, please request it in My Access section -> Access Rights and provide a description why you need it ; here also provide NDA number to speed things up for the reviewer. Finally send request.

Hi @mohamed_elsabagh I am now trying to interface CLRC663 with nRF52832 to read UID and card data.
Can you please share the references you have used for doing it?
In addition to that, if you can share the Library files it will be of great help to me.
