Hello Reeshma 
 I see you have based your code on the HRS example. However, the main code you have used seems to be from version 12 of the SDK, not 13. There are several differences between the two versions, and using the main file from SDK 12 with the softdevice, libraries and drivers of SDK 13 won't work. When trying to compile your code with SDK 13 I get several errors and warnings, all related to changes from SDK version 12 to 13. I would recommend you redo your main file, and base it on the example found in SDK 13, to eliminate as many sources of error as possible.
