depends on COAP
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.

bool "Support for CoAP extended options"
default n
depends on COAP
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.

help
This option specifies the maximum value of length field when
COAP_EXTENDED_OPTIONS_LEN is enabled. Define the value according to
user requirement.
