nrf_802154_trx_transmit_ack()

bool nrf_802154_trx_transmit_ack	(	const void *	p_transmit_buffer,
		uint32_t	delay_us,
		const nrf_802154_fal_tx_power_split_t *	p_tx_power_split )

Put the trx module into transmit ACK mode.

Note

This function may be called from nrf_802154_trx_receive_frame_received handler only. This is because in this condition only the TIMER peripheral is running and allows timed transmission.

Parameters

[in]	p_transmit_buffer	Pointer to a buffer containing ACK frame to be transmitted. Caller is responsible for preparing an ACK frame according to the 802.15.4 protocol.
[in]	delay_us	Delay (in microseconds)
[in]	p_tx_power_split	Pointer to the structure holding TX power split into raw components in dBm.

Return values

true	If the function was called in time and ACK frame is scheduled for transmission. When transmission starts the function nrf_802154_trx_transmit_ack_started will be called. When transmission is finished the function nrf_802154_trx_transmit_ack_transmitted will be called.
false	If the function was called too late and given delay_us time gap between received frame and ACK frame transmission could not be hold. The TIMER peripheral is stopped and it is not possible to trigger nrf_802154_trx_transmit_ack again without receiving another frame again. No handlers will be called.
