CONFIG_BT_CTLR_SCHED_ADVANCED

Advanced scheduling

Type: bool

Help

Enable non-overlapping placement of observer, initiator and master
roles in timespace. Uses window offset in connection updates and uses
connection parameter request in slave role to negotiate
non-overlapping placement with active master roles to avoid slave
roles drifting into active master roles in the local controller.

This feature maximizes the average data transmission amongst active
concurrent master and slave connections while other observer,
initiator, master or slave roles are active in the local controller.

Disabling this feature will lead to overlapping role in timespace
leading to skipped events amongst active roles.
