@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

@komal: I'm not sure why you need to use nrfjprog to manualy write the address to UICR. If you set it up correctly, with BOOTLOADER_REGION_START = 0x00035000, when you flash the bootloader .hex , the address will be written automatically.

Please let me know your further steps until you get the error.

If you couldn't take a sniffer trace, please send the Master Control panel log and screenshot.
