Hello, It's my first time working with NFC technology and I'm trying to use the FD-pin on a NTAG213F to send data to a microcontroller. At least use the signal transition to wake up the microcontroller from a sleep state. I understood from the datasheet that the FD pin has a default value configuration of 11b which means that by default the pin should make a transition when a reader/writer (e.g. smartphone) interacts with the tag. I doubled checked my circuit and everything should be working fine. But the FD pins seems to have no response. Am I missing something? Do I have to configure de FDP CONF bits to a different mode? If so how am I supposed to do so? I mean, is there any kind of interface to configure the ntags or change their default values??
I'm new working with ntags and NFC technology any help will be really appreciated.
