Simplified state machine by removing manual registering state.
This was done as some modems did not have all the needed at commands
for checking the registered network. Some modem run out of memory as when
checking correct network there might be so many networks available.
Manual registration still works but it does not do any checks to which network
it's registered. Moved manual registering at command earlier in state machine so it forces
registering to a correct network. Internal refactor/fix, does not affect applications.
This was left accidentally after refactoring.
It wasn't giving correct states after refactoring.
CellularContext::get_connection_status should be used instead.
Fix syncing back to at mode after ppp disconnect.
Fix AT_CellularContext flags and states to allow new connect after disconnect.
Fix that state machine is not reseted in disconnect is it's running (might be
running because of another context or new connect already started).
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.
Generic cellular module (GENERIC_AT3GPP) can by used as a default
module when porting new cellular module. It's a good starting point
and eases porting of new modules. GENERIC_AT3GPP uses only standard
3GPP AT commands when communicating with the modem.
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.
