*Advanced scheduling*

Type: ``bool``

Help
====

.. code-block:: none

    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.
