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.
Add missing license headers.
Remove semaphores to allow async operation.
Change hex format to allow binary payload.
Limit payload size to 100 bytes.
Fix missing plus char at +QCFGEXT.
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
All targets must implement soft_- and hard_power_on/off() functions which are practically same what onboard_modem_api offered.
These were seen as a duplicate features and therefore we removed this.
All targets involved have been updated to reflect the changes
When AT traces are enabled and very long AT commands are traced,
system can easily go to unwanted state. Therefore the length of the AT
traces is limited to DEBUG_MAXLEN (currently 60 characters).
This commit fixes read_hex_string, read_bytes and write to use this
limitter.
According to [3GPP-TS_24.008] the maximum size for Non-IP link MTU is 1358 octets to prevent fragmentation in the backbone network.
Therefore reduced the maximum size to follow the standard.
Removed CellularBase and AT_CellularBase from cellular stack and updated both code and unittests accordingly.
Moved property handling into AT_CellularDevice
