s13x v.2.x.x supports dynamic memory allocation so you can optimize the softdevice's RAM usage for a specific use case. You can find more details about this feature in the migration document included with the softdevice in addition to what is mentioned in the SDS.

The examples allocate more RAM than what is actually needed, hence the log messages. This allows you do add characteristics, etc to the example without getting a "no memory" assert right away.

You can find some common IRAM and IROM values at the bottom of this blogpost.

I found the answer in the project's "Target" options. But really, the error message should contain more specifics about where to go to fix the problem.

I did find this: infocenter.nordicsemi.com/.../nRF52_Series_Migration_v1.0.pdf

Which discusses the RAM settings in the migration case. But I thought I was starting with an nRF52 template.
