I am using Linux kernel version 5.4 in that for NXP diver. I am using nxp-pn5xx/pn5xx_i2c and the library is libnfc_nci_linux-1.so.0.0.0 for PN71506 IC.

As shown in below log, HAL level detecting the tag correctly, but while calling the callback function to application it sends the old or previously detected tag id continually.

Hello sir,

This is Fabian from customer support.

We would like to help you with this issue unfortunately, we aren't able to provide free-online support for PN7150 related issues based on a custom board. PN7150 isn’t recommended for new designs any more and, our support is very limited. Please explore the possibility of using PN7160

I am very sorry for the inconveniences sir but, I can only point you out to our Professional support services.

Again, I am very sorry for not being able to help you with this issue sir.

Best Regards,
Fabian
