Hey @moritzholzer, thanks for working on this!

For an easier reviewing process, I'd suggest you try to squash unnecessary commits (e.g., the merges). Please, make sure you check our commit conventions https://github.com/RIOT-OS/RIOT/blob/master/CONTRIBUTING.md#commit-conventions

Regarding the version bump, do you know whether there are plans from Wakaama on releasing a version 2.0? With this update, which is the highest LwM2M version that is supported?

[moritzholzer]

I wil squash the commits later.

The lwm2m version is 1.0, some features 1.1.
See Which LWM2M version Wakaama Client supports?

From what i can get from the issues in the wakaama repo there is not a fixed plan for a new version but it was discussed in the past without an conclusion.

There seems to be a problem with a printf on object_server.c. Check the CI output

[leandrolanzieri]

You may want to remove the Makefile.ci and run make generate-Makefile.ci in the example (IT TAKES SOME TIME) to exclude boards that can't fit the application anymore.

[leandrolanzieri]

Looks good. There's only one style comment pending. Please squash directly, so that we keep only meaningful commits in the history.

[moritzholzer]

Is it enought squashed or are less commits better?

[leandrolanzieri]

Thanks @moritzholzer. I think there are some mix ups on the commit history. I see, for example, various changes of the pkg version? (ec5d90f and e0fe270)

I would suggest having the following commits:

• version bump (updates on pkg makefiles, updates of the patches)
• changes on config and OS services (addition of random seed, Kconfig)
• adaption of contrib to new interface (changes on our object implementations and their docs)
• changes on example application

Also please check the messages. They should always start with the area of changes (e.g., pkg/wakaama, examples/lwm2m). Also, we use present tense. If you want to elaborate on large changes, do so by leaving a blank line after the short description.

Thank you @leandrolanzieri for the help:)
I did my best to restructure the commits.

[leandrolanzieri]

Looks good!

@moritzholzer there are some whitespace errors (see https://github.com/RIOT-OS/RIOT/actions/runs/11609350032/job/32530338557?pr=20930)

[moritzholzer]

I removed the whitespaces.

Before the merge queue triggers a timeout, I'll drop and requeue this one.
