CONFIG_BT_CTLR_XTAL_THRESHOLD
¶
Crystal shutdown threshold in uS
Type: int
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. This value is board dependent.
Direct dependencies¶
BT_CTLR_XTAL_ADVANCED
&& BT_LL_SW_SPLIT
&& BT_CTLR
&& BT_HCI
&& BT
(Includes any dependencies from ifs and menus.)
Default¶
1500
