Hi,

thanks for the support. I overlooked the bt-ll-sw-split snippet. After adding this, everything worked as expected.

Kind regards,

Christian

Hi Christian,

Thank you for sharing

D:/Projekte/nrf_connect_sdk/apps/test_app/src/main.c:321:5: warning: 'BT_LE_ADV_OPT_CONNECTABLE' is deprecated [-Wdeprecated-declarations]

As you stated, I see there are some artifacts here w.r.t your application from 2.7.0 that are using deprecated functionality. Could you go through the release notes and migration guides and clear up any remaining warnings?

Here's some resources that should get your through this:

Migrating from multi-image to sysbuild: https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/releases_and_maturity/migration/migration_sysbuild.html
Migration guides https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/releases_and_maturity/migration_guides.html
- Iterate through the 2.8 migration guide, 2.9 guide and 3.0 guide
If there are additional deprecated Kconfigs between 2.7.0 and 3.0.0 that are not mentioned in the previous 5 links, then you should be able to find them here https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/releases_and_maturity/release_notes.html
In case you have more questions about sysbuild, here's a great course at our academy pages https://academy.nordicsemi.com/courses/nrf-connect-sdk-intermediate/lessons/lesson-8-sysbuild/

I know this is quite a bit of work to do, but unfortunately it's not as easy as "just upgrade" w.r.t upgrading to a newer release of NCS when you're going over 4 major releases of the SDK

Kind regards,
Andreas

Hi,

thanks for your answer, here's the complete log:

devzone.nordicsemi.com/.../terminal_5F00_log.txt

I set the CONFIG variable to n.

Best regards,

Christian

Hi,

Could you attach the entire build log? There's most likely something more useful somewhere else in the log.

[quote user=""] When using v2.7.0 I also had the flag set to "no"[/quote]

Do you set 'CONFIG_BT_LL_SOFTDEVICE="no"' or "CONFIG_BT_LL_SOFTDEVICE=n"?

Kind regards,
Andreas
