Detailed Description

Function Documentation

uint8_t nrf_802154_ccaedthres_from_dbm_calculate ( int8_t dbm )

Converts a given dBm level to a CCA energy detection threshold value.

Parameters

[in] dbm Energy level in dBm used to calculate the CCAEDTHRES value.

Returns: Energy level value corresponding to the given dBm level that is to be written to the CCACTRL register.

int8_t nrf_802154_dbm_from_energy_level_calculate ( uint8_t energy_level )

Converts the energy level received during the energy detection procedure to a dBm value.

Parameters

[in] energy_level Energy level passed by nrf_802154_energy_detected.

uint32_t nrf_802154_first_symbol_timestamp_get	(	uint32_t	end_timestamp,
		uint8_t	psdu_length
	)

Calculates the timestamp of the first symbol of the preamble in a received frame.

Parameters

[in]	end_timestamp	Timestamp of the end of the last symbol in the frame, in microseconds.
[in]	psdu_length	Number of bytes in the frame PSDU.

Returns: Timestamp of the beginning of the first preamble symbol of a given frame, in microseconds.
