We are aware of the "challenge" of missing defines in the sdk_config, it's been reported, and I hope this will be addressed in future sdk's either by supporting tools or otherwise.

Clearly, it is going to be different because the examples are different - so, naturally, they will have different configurations!

Why they can't all be complete is another question ...

Absolutely!

See the above-mentioned thread!

You might also want to feed back there ...

I also assumed this but I would like to know what is causing the problem and how to fix it.

I don't really understand why the sdk_config is different for every example so we have to frankenstein multiple configs together and pray that it works. It would be nice if Nordic could provide a global config that contains all the options and we can just turn them on or off as required.

Using the RTT isn't really an option for us.

Then I assume sdk_config.h is the problem

Maybe you can consider using RTT for nrf_log instead, unless you need to use uart for logging

Yes, the code is copied from that example. The example works fine but it does not work in our project.

Did you take a look at \nRF5_SDK_15.3.0_59ac345\examples\peripheral\serial_uartes
