LPC8N04 NFC read-after-write

Question asked by Ken Roberts on Oct 10, 2019

Is it possible to do a read-after-write with the LFC8N04?

When a user NFC taps the LPC8N04 device a security code is sent which we want to use to customise the return records. We have limited control over the reader device.

We achieve this on other manufacturers silicon (Nordic) by disabling then re-enabling the NFC sub-system which forces the reader to do a re-read, is this possible with the LPC8N04? Or can it be achieved a different way?

 

Thanks.
