@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: It's pretty strange issue. Because you can update the ble_app_hrs_dfu the first time without problem, why didn't it work the second time. Could you provide the Master Control panel log. You can get the log by selectin File -> Log File.

Do you have the same issue if you enter bootloader by holding the BOOT button instead of entering if by writing to the DFU control point ?
