Is the PN7150 reset properly? Please refer to the "Reset concept" in the datasheet for the details.

Do you mean that I need to set VEN low for a while then high ? I have tried this method , it's not working.

And now I find I2C reading or writing is ok no matter sytem responses or not.

I find that setting NFC switch button in configuration menu off then on will solve the problem. But I don't

know why.
