the way of reducing softdevice resource consumption

[Gerbert Shnauer]

Hello,

in the new version of sdk (11.0.0) you support s130 only. That means the code contains both peripheral and central implementation. Does it mean that s130 consume more RAM resources than s110 and s120 separately? If so, how to reduce consumption of RAM?

Hi Gerbert,

RAM usage of the SoftDevice in s130_nrf51_2.0.0-7.alpha is alreay reduced compared with s110_nrf51_8.0.0. Look at linker scripts.

s110 on SDK 10.0.0:

MEMORY
{
  FLASH (rx) : ORIGIN = 0x18000, LENGTH = 0x28000
  RAM (rwx) :  ORIGIN = 0x20002000, LENGTH = 0x6000
}

s130 on SDK 11.0.0-2.alpha:

MEMORY
{
  FLASH (rx) : ORIGIN = 0x1b000, LENGTH = 0x25000
  RAM (rwx) :  ORIGIN = 0x20001f00, LENGTH = 0x6100
}

Although flash usage grew, now we have more RAM. :)

Well, these values are not for the SoftDevice.
