Crystal oscillator is retained between closely spaced consecutive radio events to reduce the overall number of crystal settling current consumptions. This feature maximizes radio utilization in an average role event timeslice when they are closely spaced by using a reduced offset between preparation and radio event. By disabling this feature, the controller will use a constant offset between the preparation and radio event. The controller will toggle crystal oscillator between two closely spaced radio events leading to higher average current due to increased number of crystal settling current consumptions. config BT_CTLR_XTAL_THRESHOLD int "Crystal shutdown threshold in uS" depends on BT_CTLR_XTAL_ADVANCED default 1500 help Configure the optimal delta in micro seconds between two consecutive radio events, event done to next preparation, below which (active clock) crystal will be retained.

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.

Maximum CPU time in Radio ISR will increase if this feature is selected. config BT_CTLR_LLCP_CONN int "Number of connections with worst-case overlapping procedures" default BT_MAX_CONN range 1 BT_MAX_CONN help Set the number connections for which worst-case buffer requirements for LLCP procedures must be met.
