string_to_pdp_type is only used in CellularContext classes and by having
the conversion method in CellularContext it can be used to check also
the non-standard Non-IP PDP type string.
ATHandler is part of our API so header file was moved under API folder and .cpp file was moved under device/ folder
ATHandler is used in both AT and PPP mode so it has been in slightly wrong place at the beginning.
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.
Earlier CellularDevice has owned event queue used by cellular (state machine and ATHandler for example),
but the thread used to dispatch the queue has been owned by state machine.
This commit moves the event queue thread to CellularDevice so now the ownership of cellular event queue
is in one place.
- Earlier some variables were public even though used only internally
- Also refactored variables to the end of class definitions
- Removed duplicate _property_array from CellularDevice
- Changed _impl methods as protected
Removed CellularBase and AT_CellularBase from cellular stack and updated both code and unittests accordingly.
Moved property handling into AT_CellularDevice
A new API `CellularDevice::clear()` to clean-up the modem to a default initial state.
Function is virtual so it can be overridden. The default implementation clears all PDP contexts,
but the the first one if that has APN defined as `nsapi.default-cellular-apn`.
CellularStateMachine calls `clear()` to clean-up the modem on initial `connect()`,
if the flag `cellular.clear-on-connect: true` is defined.
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.
CellularContext member variables were initialized in inheriting class.
Now in base class where they should be initialized so that every inheriting
class don't have to init them.
Disconnect was sent to all CellularContext classes even it concerned
one specific context. Some disconnect events are still sent to all
context classes. These event are coming from network and ment for all
context classes or event did not specify cid.
State machine has retry logic until device is attached to network.
After this CellularContext does the context activation e.g. connect.
There was no retry logic for context activation. Added logic to
CellularContext level so it's available for at and (upcoming)ril layers.
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.
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.
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).
