anj_exchange_udp_tx_params_t Struct Reference

#include <defs.h>

Data Fields
anj_time_duration_t	ack_timeout
double	ack_random_factor
uint16_t	max_retransmit

Detailed Description

CoAP transmission parameters (RFC 7252).

These parameters control the timing and retransmission behavior of confirmable CoAP messages sent over UDP.

The initial retransmission timeout is chosen randomly between ack_timeout and ack_timeout × ack_random_factor. With default values, this corresponds to a range of 2—3 seconds. After each retransmission, the timeout value is doubled.

Retransmissions continue until either a response is received or max_retransmit attempts have been made.

Field Documentation

ack_random_factor

double ack_random_factor

ACK_RANDOM_FACTOR multiplier applied to randomize the timeout.

ack_timeout

anj_time_duration_t ack_timeout

Initial ACK_TIMEOUT value.

max_retransmit

uint16_t max_retransmit

Maximum number of retransmissions before giving up.
