Hi Einar,

Thank you for your reply. That's good to know.

I would also be very interested if someone could comment on their experience so I won't verify this answer yet if that's okay?

Hi,

The nRF Connect SDK is tightly coupled with Zephyr. You can almost think of it as similar to a Linux distribution, where all have more or less the same kernel and surrounding basic tools etc, but add differentiations components on top of that. There is a lot of the surrounding tools and components in the nRF Connect SDK though, so the analogy is not 100%, but it gives the idea.

The Zephyr RTOS is getting more and more widespread, so if you base your firmware on Zephyr APIs and/or your own wrappers, then you should be able to reuse most of the code with other SoCs as well. The nRF Connect SDK is sort of a superset of Zephyr, and you will typically use quite a bit of features from there. That will mostly be under the hood though, and also for the proprietary components you often use Zephyr APIs (for instance if you use the SoftDevice controller as BLE controller the application code will be exactly the same as if you were using the Zephyr LL).

It will be interesting if someone else on this forum can comment on their experiences.
