Help¶

Enable GPIO interface to a Low Noise Amplifier. This allows hardware designs using LNAs 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.
