Note that documentation for random_max_start_delay config setting has
been changed to indicate that the setting is in seconds, and always has
been. No functional change.
Major changes:
- Dependency to FileHandle removed from base classes
- AT_CellularDevice owns the default FileHandle and shares it with AT -classes
- Hang-up -detection moved as CellularContext::configure_hup(). Cannot be configured via CellularDevice any more.
Result on NRF52840_DK + BG96:
GCC:
Total Static RAM memory (data + bss): 29360(+296) bytes
Total Flash memory (text + data): 130660(-832) bytes
ARM:
Total Static RAM memory (data + bss): 261554(+8) bytes
Total Flash memory (text + data): 127573(-1193) bytes
IAR:
Total Static RAM memory (data + bss): 25479(+296) bytes
Total Flash memory (text + data): 102418(-527) bytes
RAM increase is because now ATHandler is no longer created with new -operator but is now member of AT_CellularDevice,
so image tool is able to count it. Actually total RAM consumption has decreased due to removed variables.
Add a missing license header.
Remove semaphores and add +CRTDCP to support async operation.
Fix delete context and disconnect to execute just once.
Add support for NONIP PPD type.
Change CellularNetwork::clear() to virtual so it can be overridden.
Removed CellularBase and AT_CellularBase from cellular stack and updated both code and unittests accordingly.
Moved property handling into AT_CellularDevice
Earlier all unittests ended up having all flags in common from all unittest targets.
This is now improved by using googletest provided mechanism to set build time compile options
All cmake files have been modified to reflect changes (when needed)
Could not figure out a syntax for {0x00, 0x00, ..., 0x00} intitializer list yet,
so those needs to be setup by updating C/CXX flags.
GoogleTest allows you to check whether certain function throws errors.
For example:
ASSERT_ANY_THROW(mbed::HeapBlockDevice one(3050, 100));
or
ASSERT_NO_THROW(bd.init());
As MBED_ERROR is now only function that can throw errors, there is
no need to check the type of thrown object.
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.
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.
Moved methods to classes CellularDevice and CellularInformation.
SIM interface was removed to simplify cellular usage and
methods better suite new classes.
Updated greentea and unit tests.
