CONFIG_COAP_RANDOMIZE_ACK_TIMEOUT¶
Randomize initial ACK timeout, as specified in RFC 7252
Type: bool
Help¶
If enabled, the initial ACK timeout will be randomized, as specified
in RFC 7252, i.e. will be a random number between ACK_TIMEOUT and
ACK_TIMEOUT * ACK_RANDOM_FACTOR (where ACK_TIMEOUT is specified by
COAP_INIT_ACK_TIMEOUT_MS option). Otherwise, the initial ACK timeout
will be fixed to the value of COAP_INIT_ACK_TIMEOUT_MS option.
Direct dependencies¶
