Hi, is it posible to use one NTAG chip to power up and talk to another?
A bit of background:
I have two NXP microcontroller evaluation boards setup:
I believe these two boards are now effectively the same. The NFC chip is attached to the I2C interface of the MCU in each case.
What i would like to do, ideally is have one of the board wake up the other using NFC. Ultimately, I would like this to trigger a BLE connection, but one step at a time!
Is it possible for the devices to talk to each other in this way? If so, are there and tips/application notes/examples that might be helpful?
Thanks in advance for any help!

Hello,
I believe there is a confusion here, the NTAG I2C it's a passive NFC component, which means that it is not able to wake up another tag, you will need an active device in order to wake up the tag.
I would recommend you to check this webinar in order to fully understand more about this. If you have any other doubt, let me know
