- When calling socket APIs when socket is not open, NSAPI_ERROR_NO_SOCKET will be
returned instead of generic NSAPI_ERROR_DEVICE_ERROR
- If socket_send() is called when connection is not open, NSAPI_ERROR_NO_CONNECTION
will be returned instead of generic NSAPI_ERROR_DEVICE_ERROR
Multihoming documentation about interface name:
"Two character name string is concatenated with 8 bit value containing index which is incremented on each netif addition"
Cellular uses context id as index and to follow LWIP (LWIP::Interface::get_interface_name), index does not include leading zeros.
In some multithread cases there is possibility that process_oob function
was called after ATHandler was deleted. Fix is to wait if oob processing
is ongoing.
CellularContext now tries to get an IP address after connect and before
sending NSAPI_STATUS_GLOBAL_UP. Even if we don't the IP address from
the modem we will send NSAPI_STATUS_GLOBAL_UP and return success.
Modem has an ip address but for some reason some modems don't
give it to us.
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.
When using NetworkInterface::get_default_instance() application gets handle
to CellularInterface which is actually CellularContext derived from CellularInterface.
Application needs also handle to CellularDevice to open other interfaces.
This was left accidentally after refactoring.
It wasn't giving correct states after refactoring.
CellularContext::get_connection_status should be used instead.
There are two EventQueue.h in mbed-os codebase:
events/EventQueue.h
features/FEATURE_BLE/ble/pal/EventQueue.h
By accident, `mbed compile` generates includes.txt with the correct
order of include search paths. This is not the case for the CMake
exporter: targets with FEATURE_BLE enables fail to compile with errors:
mbed-os/features/cellular/framework/AT/ATHandler.h:99:60: error:
'events' has not been declared
Update all places to always include either "events/EventQueue.h"
or "ble/pal/EventQueue.h": to always find the correct header.
Information removed from the cellular subsystem trace log:
* SIM pin
* APN username and password
Added get_debug() to ATHandler.h to get the current trace state in order
to support suspend/resume of trace output.
Change usage of AT_CellularContext::stack_type_supported to
AT_CellularBase::get_property. This way we can rid of
targets overriding stack_type_supported and delete
unnecessary classes and simplify new targets.
After AT_CellularNetwork::has_registration was replaced with
CellularProperties and better
AT_CellularNetwork::set_access_technology_impl default
implementation we can delete most of the target specific classes
that inherit AT_CellularNetwork.
