Why we need to change the starting and ending address of the RAM when we add a new service?

What is the exact reason as to why we have to change the Ram starting address when we add a new Service?

Hi Rit, 

The RAM usage of softdevice will depend on what features (connections, attribute size, uuids etc) is enabled/utilized by the application side in a serialized application, so need to adjust the RAM address for softdevice.

But how exactly the memory is laid out in the ram, and where exactly does the UUID's go?

I don't know the specific address of the UUID, but adjusting the RAM address is for the softdevice to have more ram handling those extra features. The debug log will indicate how to modify the ram start address for the application.
