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.
Socket network interface tests were failing due to DICONNECTED event
being advertised, where GLOBAL_UP was expected. It turned out that
nanostack receives two events: APPL_EVENT_CONNECT and
APPL_BACKHAUL_INTERFACE_PHY_UP. The second attempt to connect obviously
returns errors, but it also causes events to be sent out to the
application. The second attempt should not take place in case the
bootstrap is already started.
I also fixed two reports being sent with DISCONNECT status, while they
are actually something else.
Set tasklet parameters before connecting to prevent the parameters to be set to 0.
The tasklet parameters are reset to 0 when wisun_tasklet_connect gets called,
thus those need to be set in the wisun_tasklet_configure_and_connect_to_network
before they are used. This is also done this way in other tasklets.
To get Wi-Sun mesh network working, also nanostack with Wi-Sun support
is needed. ws_empty_functions.c and ws_management_api.h are temporary
included here, so that wisun_tasklet will compiled without problems.
They will replaced with the official versions with next nanostack release.
mbed.h has 'using namespace mbed;', hence some of the files skip
adding required namespace to the code, it is always good to specify the
namespace around the elements in header and `using namespace` in
specific CPP files, instead of all
