How to merge SoftDevice, Bootloader and Application code into Single hex file

[Chen Chen]

Hello folks, we are currently using RedBear Lab Arduino toolchain to develop a MDBT40 based application. However we meet a lot issues on merging bootloader.hex (downloaded from this github) and Arduino exported application, i.e. the chip cannot jump from bootloader to application code successfully.

Could anyone gives some hints on how to merge bootloader.hex and Arduino exported code into single .hex file?

Thanks for the help!

You can use mergehex by Nordic to merge your hex files. Although, your issue could be because of an incompatible SoftDevice version. Looking at that bootloader hex file, it looks like it is from 1 year ago. If you are using the latest version of SoftDevice with that old bootloader hex file, maybe things will not work.
