[danielschedlacz]

Hello NXP team, I have a quastion to the PN5180 NFC-Chip. I develop a RFID-transceiver with this chip and try to read the uid of any card but i cant find the right command to do this. Can you giv me the complete command that I need to read the uid of a card?

Hello Daniel Schedlaczek:

The UID is obtained during the anticollision procedure, but there is not a simple command to simply get the UID. You need to configure the PN5180 registers and start polling for different kind of cards. I highly recommend you to download the NFC Reader Library for the PN5180 from the Software & Tools tab in the product page:

High-performance multi-protocol full NFC Forum-comp|NXP

Together with this library you will find example projects that show how to configure the PN5180, e.g. the Basic Discovery Loop example, which shows how to poll for different technologies and protocols.

I hope this helps.

Regards!
