#include <nrf_802154/driver/src/mac_features/nrf_802154_csma_ca_backoff.h>

Gets the number of backoff periods to wait before the next CCA attempt of CSMA/CA.

When test modes are not enabled, the number of backoff periods is a random value in the range from 0 to (2^BE - 1), where BE is the current backoff exponent, as defined in IEEE Std. 802.15.4.

When test modes are enabled the returned value depends on the value returned by nrf_802154_pib_test_mode_csmaca_backoff_get .

Note

Consecutive calls to this function may return different values.

Parameters

[in]

be

Backoff Exponent. Allowed range 0...8.

Returns

Number of backoff periods to wait before the next CCA attempt
