@komal: Which project have you used? Have you used the ble_app_hrs_dfu.uvproj project ? The project should have the following file included : bootloader_util_arm.c, ble_dfu.c, dfu_app_handler.c

You can check if ble_dfu_init() is called.

bootloader.hex

ble_app_hrs_dfu.hex

On newer SDK (where you have to update the python code in ble_dfu_send_hex\dfu into C:\Program Files (x86)\Nordic Semiconductor\Master Control Panel\3.7.1.8567\lib\dfu) such as SDK v7.1 the Master Control Panel can do update seamlessly from the dfu buttonless application.
