@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: If you have the bootloader setup correctly, the 0x10001014 address should be written automatically when flashing the bootloader hex file. I'm afraid that all the solutions I have for now for you is either:

• Use the SDK v6.0 gcc bootloader that provided here.

• Use Keil (free version) to compile the bootloader on SDK v6.1 or later. You will have the same file as the bootloader.hex file I provided earlier and you can modify it.

I can get back to make an example for bootloader SDK v6.1 to be compiled on gcc when I have more time. It's pretty limited workforce in our team now due to Easter holiday.
