CONFIG_ENTROPY_NRF5_THR_THRESHOLD

Thread-mode random number pool low-water threshold

Type: int

Help

Low water-mark threshold in bytes to trigger entropy generation for thread mode consumers. As soon as the number of available bytes in the buffer goes below this number hardware entropy generation will be started.

Direct dependencies

ENTROPY_NRF5_RNG && !ENTROPY_NRF_FORCE_ALT && ENTROPY_GENERATOR

(Includes any dependencies from ifs and menus.)

Defaults

No defaults. Implicitly defaults to the empty string.
