Out of memory when porting to SDK 2.8.0

[uknoblic]

Dear nordic support team,

after having migrated my project to SDK release 2.8.0, the following message appears in the logs:

 <dbg> bt_sdc_hci_driver: configure_memory_usage: BT mempool size: 2983, required: 2960

What is the reason for this and how to fix it? There seems to be an insible config parameter CONFIG_BT_SDC_ADDITIONAL_MEMORY, but i can't set it via Kconfig

Regards

Ulf

Hi Ulf,

It is likely that the SoftDevice Controller (SDC) memory requirements have increased in the newer SDK version.

There seems to be an insible config parameter CONFIG_BT_SDC_ADDITIONAL_MEMORY, but i can't set it via Kconfig

Have you tried adding CONFIG_BT_SDC_ADDITIONAL_MEMORY=y to your prj.conf file?

Which SDK version did you migrate from?

Hi, i migrated from 2.6.2 to 2.8.0. But in the meatime the problem was solved: the mentioned debug message is just this - a debug message. I tells that there is ENOUGH memory available. The reason for me application not working anymore is the fact, that i enabled logging, and this seems to interfere with the BT stack. Anyway - problem solved for now! Thanks
