Size of soft device

[Sergii]

Hello,

I use nrf52832 with 65 kb RAM.

I can't understand why soft device takes about 30k RAM memory.

I see "reserved_ram" has 30k.

Can I change size for 20k for an example? which will effect?

Hi Sergii, 

The amount of RAM used by the softdevice depends on its role. If you the nRF is a connectable peripheral (such as ble_app_blinky), you need to store your services/characteristics, connection information, and so on. So if you want to use less ram, you need to have less softdevice related tasks (connections, services, etc.).

Hi,

Thank you for you response.

How could I control how much RAM do I need for SoftDevice in a project?

Hi Sergii, 

Please see the Adjustment of RAM and Flash memory documentation. 

The support staff is reduced during the summer holidays, and you may experience delayed answers.
