I am unable to read any uart input when I configure UART1 with nRF9160DK.
Please let me know if anything is wrong in my code/config

I cannot see any data on my console even after sending data continuously to the console. Please guide me through the problem. I am also attaching the folder.
I add the folder in : D:\Softwares\SDK\v1.3.0\nrf\samples\nrf9160\uart
