CONFIG_BT_CTLR_LOW_LAT
¶
Low latency non-negotiating event preemption
Type: bool
Help¶
Use low latency non-negotiating event preemption. This reduces Radio ISR latencies by the controller event scheduling framework. Consequently, this reduces on-air radio utilization due to redundant radio state switches.
Direct dependencies¶
BT_LL_SW_SPLIT
&& BT_CTLR
&& BT_HCI
&& BT
(Includes any dependencies from ifs and menus.)
Default¶
y if
