Hi
I have my application running on nRF52 on SDK 11 (Softdevice S132 version 2.0). I am using 1 peripheral and 6 central links in my application. I am migrating the application to SDK14.2, Softdevice 5.0 and facing issue when using 6 Central links.
I get "region RAM overflowed with stack" error if I use 6 Central links. Application works fine with 3 central links but if I increase the number of central links and change the RAM addresses accordingly then I get the above error. Below are the macros I have set in sdk_config.h
1. NRF_SDH_BLE_CENTRAL_LINK_COUNT 6
2. NRF_SDH_BLE_PERIPHERAL_LINK_COUNT 1
3. NRF_SDH_BLE_VS_UUID_COUNT 3
In the linker file, I was giving around 48K of RAM to application in the older SDK for 6 central links. But with the new SDK, I can give only 40K RAM to application for 3 Central links. It doesn't let me compile for more then 3 links.
The application was working fine with the same configuration with the SDK11 and Softdevice 2.0. Has the Softdevice RAM usage increased from v2.0 to 5.0? Are there any configurations I can change to reduce this usage?
