It would be probably good idea to also remove tools/docgen.py and asciidoc.mk, but asciidoc.mk is still mentioned under `cloud/doc`, which may contain some useful info which we'll need at least to review before removing. PUBLISHED_FROM=faf454d4c52a2f07ea8ac084cf0bd11a0c9c9b3b

Parse COAP message and fills mg_coap_message and returns cm->flags.
|
|
This is a helper function.
|
|
|
|
NOTE: usually CoAP work over UDP, so lack of data means format error,
|
|
but in theory it is possible to use CoAP over TCP (according to RFC)
|
|
|
|
The caller have to check results and treat COAP_NOT_ENOUGH_DATA according to
|
|
underlying protocol:
|
|
|
|
- in case of UDP COAP_NOT_ENOUGH_DATA means COAP_FORMAT_ERROR,
|
|
- in case of TCP client can try to receive more data
|
|
|
|
Return value: see `mg_coap_send_message()`
