you can ofcourse use them one after the other (should not run concurrently). While distance measurement is enabled, you should not have direction finding service active and vice versa.

So it is not possible to use the Distance Measurement Library to calculate the distance and then notify the clients with the results using the Distance and Direction Finding Service?

It is not possible to mix DM and Direction Finding as of now. These two features are very radio intensive and work mostly assuming that they will manage to get the radio time when requested.

[quote user=""]In the example advertising and scanning is used in order to configure the boards for their respective role in the distance measurements. Since my boards are connected already I am not sure how to correctly configure the boards to start a distance measurement directly and skip the advertising part. Or if it is even possible to skip the advertising part.[/quote]

No DM uses the radio by requesting time using MPSL timeslot library. It is not using any advertising roles as per say, but it uses nRF RADIO using timeslots.
