nrf_802154_trx_transmit_ack()

bool nrf_802154_trx_transmit_ack	(	const void *	p_transmit_buffer,
		uint32_t	delay_us )

Puts 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)

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.
