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_LL_SW_LEGACY) && BT_CTLR && BT_HCI && BT

(Includes any dependencies from ifs and menus.)
