Hi,

This number is an internal parameter and subject to change. I checked with the team, and in your described usecase when one of the roles is blocked it will be scheduled for the next event. However if the advertisement is blocking the scan event, scanning will be cancelled for the entire interval. To avoid long periods without scanning the recommendation is to use shorter scan intervals. This means the scanner will spend some time changing channel, but you will avoid not scanning for long periods if an advertisement is scheduled instead of the scanner.

Hi,

Thanks for the answer. I highlighted a text that says "for a few times". Would we be able to define this "few number of times" that an advertising has to be blocked in order to get prioritized?

Hi,

Scheduling priorities will be found here. SoftDevice timing-activities and priorities

Basically it will be first come, first serve until one of the roles has been blocked a few times, then that role will have priority over the other for the next event.
