In order to merge files, you'll want to check out the mergehex function here. So does the DFU to SDK 11 work fine, but the DFU from SDK 11 to SDK 12.3.0 not work as well?

@Bjorn-kvaale , Thanks your reply. I think problem in creating zip file , i am trying like this

nrfutil pkg generate --hw-version 51 --sd-req 0x80 --application-version 4
--application app.hex --key-file key.pem app_dfu_package.zip

Now showing my app UNKNOWN ERROR(8202)

Are you using softdevice s130_nrf51_2.0.0? What output are you getting from the nrfutil command? Also, take a look at this devzone case here. Make sure you are using the correct softdevice (SD) code after the --sd-req command. It seems like the correct SD for SDK 12.3.0 is the s130 v2.0.1 SD. Which would make the code 0x87. But double check to make sure you are using the same SD. You can find the different SD codes by typing nrfutil pkg generate --help in a command prompt window.

@Bjorn-kvaale , Thanks for supporting. I think i am struggling in Build the bootloader. 321.jpg i want to know what is exe used for like nrfutil ? or other ?

I am using keil to build the bootloader. But if you don't have access to Keil, you can always build the bootloader using either armgcc or segger embedded studio. Segger Embedded Studio is free to use with the Nordic SDK & is in my opinion a great IDE. Here's a youtube playlist for getting started with SES. Shouldn't be too difficult. :) I didn't quite understand your other question. Do you want to know whether you can build the bootloader using nrfutil or another program?
