NXP Ntag i2c plus tag not getting detected via I2C

Hello,

   I am using NXP Ntag i2C plus tag. I am not able to communicate with the tag via I2C. However I am able to read and write via NFC.

Following were the different methods tried out

1)I checked with the NTAG I2C Explorer- Peek and Poke Utility. When scanned for the devices, it shows "I2C device not found"

2)I read all the settings like that of Configuration register , Session Register, the 0th block of NTAG etc via NFC and checked them against the working tag. All are same.

I tried changing the Slave address via I2C,from then this tag doesn't seem to work via I2C. I am not sure if changing the slave address killed the tag to write via I2C as Peek and Poke Utility scans for all the slave addresses.

Please help me out to resolve this issue as soon as possible.

Thank you
