CONFIG_UART_3_NRF_ASYNC_LOW_POWER

Low power mode

Type: bool

Help

When enabled, UARTE is enabled before each TX or RX usage and disabled
when not used. Disabling UARTE while in idle allows to achieve lowest
power consumption. It is only feasible if receiver is not always on.

Direct dependencies

UART_ASYNC_API && UART_3_NRF_UARTE && UART_NRFX && SERIAL

(Includes any dependencies from ifs and menus.)

Defaults

No defaults. Implicitly defaults to n.
