CONFIG_BT_CTLR_FEM_NRF21540¶

nRF21540 GPIO interface

Type: bool

Help¶

Enable PDN and CSN GPIO interface for the nRF21540. This allows
hardware designs using the nRF21540 to let the controller toggle
their state based on radio activity.

Direct dependencies¶

!SOC_SERIES_NRF51X && BT_LL_SW_SPLIT && BT_CTLR && BT_HCI && BT

(Includes any dependencies from ifs and menus.)

Defaults¶

No defaults. Implicitly defaults to n.
