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.
