CONFIG_BT_CTLR_SCHED_ADVANCED

Advanced scheduling

Type: bool

Help

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

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

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