Excellent. I will do that now. FYI you could also close any of your tickets by verifying the answers that you think helped you.

Have a great day,

Perhaps you misunderstood how Kconfigs are used. The file I referred to in my previous reply is the Kconfig definition. To configure them for your project, the simplest way is to update your prj.conf.

For example, if you want to set the SW Revision, the relevant definitions in Kconfig.dis are:

https://github.com/nrfconnect/sdk-zephyr/blob/v3.2.99-ncs2/subsys/bluetooth/services/Kconfig.dis#L134-L143

config BT_DIS_SW_REV
	bool "DIS Software Revision characteristic"
	help
	  Enable Software Revision characteristic in Device Information Service.

config BT_DIS_SW_REV_STR
	string "Software revision"
	depends on BT_DIS_SW_REV
	help
	  Enable software revision characteristic in Device Information Service.

From that, we would infer that we need to update our project prj.conf file as followed:

CONFIG_BT_DIS_SW_REV=y
CONFIG_BT_DIS_SW_REV_STR="2023.03.29.01"

I hope that example helps you understand my idea better.

Further see also: Build and Configuration Systems — Zephyr Project documentation (nRF Connect SDK) (nordicsemi.com) and its subpages (which include the first link).

I found the file in my SDK. But I naturally don't want to modify the files in the SDK. Where can a modified version of that file be placed in my project folder so that it will override the one in the SDK?

Hi Bret,

You can find the Kconfig for DIS defined in the zephyr part of the SDK.
https://github.com/nrfconnect/sdk-zephyr/blob/v3.2.99-ncs2/subsys/bluetooth/services/Kconfig.dis

On your SDK installation, it would be in <SDK root>/zephyr/subsys/bluetooth/services.
