This is a linker error, it is complaining that it cannot find the definition of nrf_twi_sensor_reg_write in your project. Please make sure if you have included nrf_two_sensor.c into your project to compile and that the nrf_twi_sensor.h file is included as the header file inclusion in lps22hb.c

Dewal,

To get best response from the community, you need to describe more.

What error number you are getting when calling that function. Have you tried usin gthe reference example that I linked in my earlier reply? Did you try to debug the error in any way? which instruction inside that API has the failure exactly?

We do not any example using the driver for lps22hb available in our SDK.

You can find a reference example in this thread in the attached zip file to get an idea on how to use the API from the driver.
