By default CoAP will create a copy of the whole data to be passed to application and it keeps the backward compatibility.
If enabled, application must NOT free the payload when it gets the COAP_STATUS_PARSER_BLOCKWISE_MSG_RECEIVED status.
And application must call sn_coap_protocol_block_remove() instead.
- Reduce heap footprint by storing only single block when receiving a blockwise message.
* User is now responsible of freeing the data by calling sn_coap_protocol_block_remove() and must not free the payload separately.
- Bug fix: Request blockwise transfer if incoming payload length is too large and when it comes without block indication.
- Store ACK's also into duplicate info list.
- ROM size optimization. Flash size has gone down ~1100 bytes.
**Closed issues:**
- IOTCLT-3592 - Client does not handle Duplicate ACK messages during blockwise registration correctly
Make sn_coap_protocol_linked_list_duplication_info_remove API to public. User might want to delete some messages from the duplicate list.
Enable support for unified client configuration.
- Remove dependency to yotta tool
- Do not remove stored (GET) blockwise message when EMPTY ACK received. When non piggybacked response mode is used original GET request must not be removed from the stored message list.Message is needed for building the next (GET) blockwise message.
- Move definitions to sn_config.h
- Add function that can be used to clear the received blockwise payloads for example in the case of a connection error.
- Silence compiler warning when CoAP duplicate detection is enabled.
- Bug fix: Remove timed out blockwise message from resend queue. If blockwise message was timed out message was still kept in the resend queue which causes unnecessary reconnections on client side.
- Documentation: Document all the available macros.
Fix error: IIOTCLT-2769 - mbed-coap: extra response received after registration
Added own flag to enable blockwise support, without setting default blockwise
payload size. This allows to receive blockwise messages while still sending
without blockwise.
Fix CoAP request blockwise response handling
When request is sent, response can have blockwise option set. All requests must
be stored to the linked list.
Fixes error: IOTCLT-2506 [GitHub] Cannot set registration time if server does not use max age option
Improvements; Extend blockwise message transfer status to have states for sending as well.
NOTE! These are internal changes required for cloud client. This has no direct relevance to any mbed-os functionality.
Nanostack related files moved under 'feature/nanostack'
Common libraries moved to 'features/frameworks'
Allow FEATURE_COMMON_PAL still to be defined in the build so
that we don't break any builds.
