How can I combine Hex files?

Question

Hi.
I'm using nRF51822, SDK10.0.0, S130.
Hex files : Soft device, Application, bootloader.
I want to download at once.
How can I combine Hex files to make them 1 file? 
 And could you let me know BASE ADDRESS of Soft device, Application, bootloader?
I need your help.

You can use mergehex included in the nRF5x-Command-Line-Tools package (you can download it from here: www.nordicsemi.com/.../nRF52832 
 You can use it like this: 
 mergehex --merge sd.hex app.hex bl.hex --output out.hex
 
 Hexfiles already have the offest address information included, so you don't need to specify this in the command line, assuming that the files have been compiled using the correct offset address. 
 
 Softdevice starts at address 0x0 
 Application starts where the softdevice ends. You need to look in the softdevice spec to find this address. For S130 v2.0.0 this is 0x1B000 
 Bootloader starts at address 0x3C000 , or whatever you specify in BOOTLOADER_REGION_START 
 
 You can also check the base address of the hex file by opening it up in a text editor and look at the first two lines: 
 :02000004 0001 F9 
:10 B000 0088330020F5B001000FB1010011B101003B 
 This means that the offset address is 0x1B000 ( read more here )
