Field Documentation

ack_random_percent

uint16_t coap_transmission_parameters::ack_random_percent

Set CoAP ack random factor.

A value of 150 means a factor of 1.5. A value of 0 defaults to CONFIG_COAP_ACK_RANDOM_PERCENT. The value must be >= 100.

ack_timeout

uint32_t coap_transmission_parameters::ack_timeout

Initial ACK timeout.

Value is used as a base value to retry pending CoAP packets.

coap_backoff_percent

uint16_t coap_transmission_parameters::coap_backoff_percent

Set CoAP retry backoff factor.

A value of 200 means a factor of 2.0.

max_retransmission

uint8_t coap_transmission_parameters::max_retransmission

Maximum number of retransmissions.
