nRF52832 Softdevice + DFU + Application in one file having problem

[Jamal]

Hi everyone,

I am using nRF52832-QFAA in a product which is completed and we are going to mass produce the product. 

We have 3 files. Softdevice, DFU and Application. We want to give our supplier a single file which can be burned in to the chip before assembly.

I succeeded in combining all 3 files together but when the hardware starts, it enters DFU mode. We want it to go to application.

I already checked some tickets here on Nordic Devzone which illustrate this problem and most of the people have added a fourth hex file that should be combine with final hex file.

I tried that but could not succeed. I am using SDK15.0.0

All those tickets explained method for older SDKs and i think that might be the problem.

I have attached one of those hex files. I am using mergehex tool to combine the hex files.

Please assist me if anyone has a solution.

Thank you.

Use nrfutil to generate the proper bootloader settings page for your application. You should then be able to merge it into the combinded hex file.
