I am working on NT3H2211 NTAG I2C.

I Could read/ write to the NFC chip through the host microcontroller and a NFC device.

Now all of sudden the I can neither read nor write into the NFC chip through I2C from the host MCU, but I can read/ write NDEF mesages through my mobile phone (NFC device). I can also read registers using the NXP Android app.


I check the I2C pin, everything is correct.


Can someone please tell me whats going on here?


Thank You
