How to configurate SoftDevice RAM usage?

I am working on nRF51422 with SDK 12.3.0, S130 v2.0.1, Keil C.

I got a problem in initialization my custom service. When I add some characteristic to SoftDevice, it returns NRF_ERROR_NO_MEM. I have some RAM space in application region for SoftDevice, how to configure RAM for SoftDevice?

  • There are so many Q&S on this forum as well as description in SD release documents. Could you check particular chapter "SoftDevice RAM usage" in "s13x_nrf5x_2.0.1_migration-document.pdf" attached to S130 release in release ZIP? Which part is unclear?
