What data do you want to send on UART? You need to parse the reply from the TWI slave in twi_handler and then you can send the result over UART using NRF_LOG_INFO macro, etc.

I have changed the DEVICE_ADDR and defined the registers from where i need to read the data. what are the things that need to be done to make that data to be displayed on the tera term.

Hi,

It looks like the ds3231 chip is interfaced though TWI/I2C interface. There is an TWI_sensor example in our SDK showing how to interface TWI/I2C sensors. You can use the TWI_scanner example to find the address of the slave if you are unsure of this.

Best regards,
Jørgen
