| Do not enable this for normal use. |

| config COAP_WELL_KNOWN_BLOCK_WISE |
| bool "CoAP ./well-known/core services block wise support" |
| help |
| This option enables the block wise support of CoAP response |
| to ./well-known/core request. Without this option all resource's |
| information will be sent in a single IP packet (can be multiple |
| fragments depends on MTU size). This will be useful in mesh kind |
| of networks. |

| Maximum size of CoAP block. Valid values are 16, 32, 64, 128, |
| 256, 512 and 1024. |

| config COAP_EXTENDED_OPTIONS_LEN |
| bool "Support for CoAP extended options" |
| help |
| This option enables the parsing of extended CoAP options length. |
| CoAP extended options length can be 2 byte value, which |
| requires more memory. User can save memory by disabling this. |
| That means only length of maximum 12 bytes are supported by default. |
| Enable this if length field going to bigger that 12. |
| |
| config COAP_EXTENDED_OPTIONS_LEN_VALUE |
| int "CoAP extended options length value" |
| default 13 |
| depends on COAP_EXTENDED_OPTIONS_LEN |
| help |
| This option specifies the maximum value of length field when |
| COAP_EXTENDED_OPTIONS_LEN is enabled. Define the value according to |
| user requirement. |

| bool "Randomize initial ACK timeout, as specified in RFC 7252" |
| default y |
| 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. |

| This option enables MQTT-style wildcards in path. Disable it if |
| resource path may contain plus or hash symbol. |
