-Taken modification for adding IID in BR info structure.
-Added API to get RPL info for Wi-SUN router and BR.
-Added API to get routing table info from BR.
Added support to Wi-SUN tasklet for following mbed-mesh-api .json configuration options:
wisun-uc-channel-function
wisun-bc-channel-function
wisun-uc-fixed-channel
wisun-bc-fixed-channel
wisun-bc-interval
wisun-bc-dwell-interval
wisun-uc-dwell-interval
This allows e.g. enabling single channel configuration for testing.
This pull request does not change existing functionality since when
defaults from mbed-mesh-api .json are used, no new or changed
ws_management_* interface calls are made.
MBED_DEPRECATE macros is added to string-based APIs.
New, non-string-based APIs are added in their place.
Wiced binaries rebuilt
Any existing stubs or mocks are adjusted to compile and run with the newly added non-string based functions.
Wi-SUN mesh API uses now nanostack certificate interface with length parameters.
This enables that either PEM or DER formatted certificates can be used. Using
the length configuration for certificates and keys is optional, so existing
applications using the PEM certificates do not require changes.
Deprecate wait() in favour of acquire(), try_acquire(),
try_acquire_for() and try_acquire_until().
Brings Semaphore more into line with CMSIS-RTOS 2 (which uses "acquire"),
itself (as it has "release"), and other classes having "try", "try for"
and "try until".
Also steps away from vague "wait" term - the primary operation here is
to acquire the semaphore, and this will of course sleep.
Only release if the current _connect_status is CONNECTING. If the semaphore is released many times for each connect, then the next connect will not wait(), as it will be able to decrement the semaphore imediatelly.
UBLOX_EVK_ODIN_W2 advertises more events than we expect.
1) When disconnecting first network connectivity is lost and then an
actual disconnection event arrives. The first one is unexpected.
2) When reconnecting MESH_BOOTSTRAP_START_FAILED shows up, but the board
eventually manages to connect
At the start-up, there was 2 NSAPI_STATUS_CONNECTING callbacks,
so extra one removed from ThreadInterface.cpp.
At the network lost case, there was NSAPI_STATUS_DISCONNECTED and
NSAPI_STATUS_LOCAL_UP callbacks. NSAPI_STATUS_DISCONNECTED has been removed,
since the NSAPI_STATUS_LOCAL_UP is enought.
