*Advanced scheduling central preferred connection spacing*

Type: ``int``

Help
====

.. code-block:: none

    The central preferred connection spacing defines an additional spacing
    in microseconds, added to the fixed ~1250 us spacing obtained by enabling
    BT_CTLR_SCHED_ADVANCED. Specifying 0 (default) will obtain a spacing of
    ~1250 us, whereas specifying 1250 will yield a spacing of ~2500 us.
    The spacing is defined as the distance in time between the anchor points
    of the established central role connections.
    The precision is determined by the resolution of the platform dependent
    ticker clock.
    When spefifying values above 6.25 ms, the spacing may be unobtainable if
    the connection interval becomes smaller than the total spacing. In that
    case, modulo is applied and a total spacing of 15 ms on a 10 ms connection
    interval yields 5 ms spacing.
    For multiple connections, it may become impossible to honor the preferred
    spacing, in which case overlapping will occur.
