Fields
Field
Declared as
Description
uint32_t
Minimum spacing before first retransmission when ACK is not received, in milliseconds (RFC7252 default value is 2000ms).
uint8_t
Numerator of ACK_RANDOM_FACTOR used to calculate maximum spacing before first retransmission when ACK is not received (RFC7252 default value of ACK_RANDOM_FACTOR is 1.5; must not be decreased below 1).
uint8_t
Denominator of ACK_RANDOM_FACTOR used to calculate maximum spacing before first retransmission when ACK is not received (RFC7252 default value of ACK_RANDOM_FACTOR is 1.5; must not be decreased below 1).
uint8_t
Maximum number of retransmissions for CoAP Confirmable messages (RFC7252 default value is 4).

Function
Description
Converts a pointer to `otCoapTxParameters` to `Coap::TxParamters` If the pointer is `nullptr`, the default parameters are used instead.
Sends a CoAP request with custom transmission parameters. If a response for a request is expected, respective function and context information should be provided. If no response is expected, these arguments should be NULL pointers.
Sends a CoAP response from the server with custom transmission parameters.
Sends a CoAP request block-wise with custom transmission parameters. Is available when OPENTHREAD_CONFIG_COAP_BLOCKWISE_TRANSFER_ENABLE configuration is enabled. If a response for a request is expected, respective function and context information should be provided. If the response is expected to be block-wise, a respective hook function should be provided. If no response is expected, these arguments should be NULL pointers.
