twi_sensor sdk example doesn't get any data???

Question

Hi, 
 I am using nRF5_SDK_15.3.0_59ac345 for nRF52840 DK. I am running the sdk example "nRF5_SDK_15.3.0_59ac345\examples\peripheral	wi_sensor" on nrf52840. When I am opened a serial terminal on putty It doesn't get any data. Any suggestions...... In the attached image below after the highlighted portion doesn't executed.I am getting m_xfer_done as false value.

Regards, 
 Eisenheim

Have you tried the TWI scanner example to verify that your nRF can actually see the sensor? 
 Have you used an oscilloscope or analyser to see what's happening on the wires?

Hi awneil, 
 Thanks for your suggestions. 
 I am tried the TWI scanner example. I get the output as "No device was found." Is my sensors are working not properly?

That shows that your code is not communicating with your sensor. 
 There are many possible reasons for that - so you need to test, investigate, and debug to find out what is going wrong. 
 Again, an Oscilloscope will be indispensable in that ...
