nRF5 is indeed inferior SDK of the 2 (thus abandoned). Also I dislike that a big chunk of the stack there is a binary blob. Regarding the code organization, not sure what toolchain you used, but the latest recommendation for nRF5 (Segger studio) could make it fairly easy to do this, but manually opening the project config files and changing them, not through the GUI. nRF Connect is a different world, comes with a lot more options, some really rooted in Zephyr OS, some lessons learned from the prior SDK. And if you're familiar with Linux build configuration system, that is basically what Zephyr brings to the table (comes from Linux foundation). But yeah all that flexibility comes as a penalty when you want simple stuff, compared to ESP32-Sx

Yes, I ended up editing the .emProject files by hand. It worked, but it felt like I was doing something wrong. I assume that you are referring to the soft device blob? Has that been abandoned in nRF Connect?

  There is a Zephyr BLE stack that can be used as well as a SoftDevice stack but SoftDevice isn't a huge binary anymore, much more modular to save code space.

  > I assume that you are referring to the soft device blob? Has that been abandoned in nRF Connect? Quite, yes. They took the ZephyrOS approach, but it comes with a learning curve penalty, unless you go the easy route of nRF Connect GUI. In that case you do have some limitations of how you organize the code base (so that the GUI works), but even that is miles ahead in configuration compared with to the nRF5 SDK + Segger Studio.

I have been out of this area for almost a decade now, but I have very fond memories of the nRF5 SDK. When I was evaluating the (then new) Nordic BLE SoC's for future products it was so much nicer than the TI CC2540 we had used in our first BLE device.
