CONFIG_BT_TICKER_LOW_LAT¶

Ticker low latency mode

Type: bool

Help¶

This option enables legacy ticker scheduling which defers overlapping
ticker node timeouts and thereby prevents ticker interrupts during
radio RX/TX. Enabling this option disables the ticker priority- and
'must expire' features.

Direct dependencies¶

BT_LL_SW_SPLIT && BT_CTLR && BT_HCI && BT

(Includes any dependencies from ifs and menus.)

Default¶

y if SOC_SERIES_NRF51X
