void ack_timout_cb ( void *  cb_timer_element )

static

Callback function for ACK timeout.

This function is called if the ACK timeout timer fires.

Parameters

parameter

Pointer to trx_id

void ack_transmission_done

(

trx_id_t

trx_id

)

Handles end of ACK transmission.

This function is called with the TXFE IRQ. It handles further processing after an ACK has been transmitted.

Parameters

trx_id

Id of the corresponding trx

bool is_ack_valid

(

trx_id_t

trx_id

)

Checks if received ACK is an valid ACK frame.

Parameters

trx_id

Transceiver identifier

Returns

true if ACK frame is valid, else false

bool is_frame_an_ack

(

trx_id_t

trx_id

)

Checks if received frame is an ACK frame.

Parameters

trx_id

void start_ack_wait_timer

(

trx_id_t

trx_id

)

Starts the timer to wait for an ACK reception.

Parameters

trx_id
