Hello!
First of all, thank you for reading my post, and for your help. I would need advice in the following:
Currently, I am working with an Arduino and with a NFC breakout board from Adafruit, the PN532. I know that there is much development to be done with the libraries for this NFC controller, and right now it is far from having all the capabilities that it could have. It isn't capable, right now, to provide direct interaction with other NFC devices like smartphones. But I believe it is already capable of "tag emulation"; to act like a NFC tag and be written and read.
I wonder, do you know if there is currently a way to use the Arduino to put this NFC controller in tag emulation mode, and then, write a message to it from the Arduino, so it can be read by a NFC device like a phone? With this, I could be able to communicate to the phone in the way I need.
Thank you again and have a good day!
