This was left accidentally after refactoring.
It wasn't giving correct states after refactoring.
CellularContext::get_connection_status should be used instead.
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.
-added an API for checking network eps ciot optimization support
-renamed the API for getting the UE parameters
-the API for setting the UE parameters includes now a callback, which
will be called once network support for eps ciot optimization is known
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.
Updated cellular debug trace prints:
- Removed unnecessary prints.
- Tracing more in DEBUG level.
- Read/write bytes not printed on big packets.
- Signal quality (RSSI) traced to log network problems.
- Dismissed AT data is traced.
- Modem type and firmware version are traced.
Network registration returns NotRegistered instead of StatusNotAvailable,
because that's not in 3GPP TS 27.007.
If sequence from buffer contains tag but symbol before tag is same as
first symbol of the tag, then the tag wasn't detected.
For example, "\r\n" tag was not found from "\r\r\nOK" sequence.
Static Thread methods and signal methods have been deprecated. Remove
all references in the main code, and most of the tests. Some tests of
the deprecated APIs themselves remain.
