about ncs ble stack

[Liny]

I'm developing a project for nRF54 using NCS. I have a question regarding the placement of the BLE protocol stack. In the previous nRF5 SDK, the protocol stack was usually stored at a fixed address, occupying about 150KB. In the new NCS, do I need to reserve a dedicated memory block for the protocol stack to store its code, parameters, whitelist data, etc.? by the way ，how much Flash and RAM does the protocol stack approximately occupy?

thanks

The new SDK has dynamic flash and RAM usage because the SD is linked in just like any other C library.

Flash and RAM usage thus depends on how you configure your application, i.e. you have a lot more usage when both central and peripherial mode was enabled compared to pure peripherial configurations.
