How do I know how much space softdevice occupies?

Hi, 

You can take a look at s112_nrf52_6.1.1_release-notes.pdf under nRF5_SDK_15.3.0_59ac345\components\softdevice\s112\doc:

The combined MBR and SoftDevice memory requirements for this version are the same as for the s112_nrf52_6.1.0:
Flash: 100.0 kB (0x19000 bytes).
RAM: 3.86 kB (0xF70 bytes). This is the minimum required memory.

This Adjustment of RAM and Flash memory doc. might help.

Amanda
