Writing and then reading NDEF text to/from the Qwiic Dynamic NFC/RFID Tag

Hey Guys,

For a prototype I am working on, there is a need for an App to write some NDEF text data to the tag and then after a short delay (while the hardware is changing the text), read the text back by the App.

Some questions:

  1. Is this possible with only a single NFC interaction (meaning the user approaches the tag with his/her phone and does not need to re-approach it again till the end of this short session?

  2. Is there a sample in the ST25DV64KC Arduino Library that can help me get started to handle the hardware side of this?

I have with me a couple of the Qwiic Dynamic NFC Tags I bought from you guys last week.

Thank you,

Nir
