Huawei LTE modems use AT^SYSCFGEX and AT^SYSINFOEX instead of
AT^SYSCFG and AT^SYSINFO.
If we want to be able to attach on LTE with this modem, we must use
AT^SYSCFGEX to configure rat mode and band. Using AT^SYSCFG, mode any
means UMTS or GSM.
Add support for automatic context activation by adding read_settings.
It also adds detach_shutdown to make sure context is cleaned up when
network registration is lost.
This is a rudimentary implementation that contains technology and RSSI
and BitErrorRate, plus RSRQ/RSRP for LTE networks. More data can be
added as needed.
This implementations uses the 'Get Signal Strength' QMI method to retrieve
the data. Operator fields (MNC, LAC, etc) can be gotten from the 'Serving
Cell' method if needed, but since this data is already provided in the
NetworkRegistration object it doesn't seem necessary to repeat it here
when an additional communication to the modem is required.
This patch fixes up some fallout from the merging of the udev and udevng
modules.
i) The 'serial' modems in question are not necessarily serial modems at
all; for example, the N900 ISI modems appear as network devices and don't
have a devnode. This patch relaxes the requirement that a devnode exist.
ii) The modem driver was being set to 'legacy', which is a remnant of
an earlier approach to merging these modules. The driver needs to be
properly set to the value of the OFONO_DRIVER property in order for the
setup function to be found.
iii) The serial modem's private data was being added to the modem
structure incorrectly...
In particular point iii) above shows that there is essentially nobody
using these devices which makes modifications in this area tricky.
When registering callbacks before ofono_netreg_register(), callbacks
will use the netreg api which might lead into undefined behaviour,
because certain fields aren't yet initilized.
added new DBUS methods RegisterAgent and UnregisterAgent to
Networkmonitor interface so that any client of ofono can register for
serving cell updates. Added new agent interface NetworkMonitorAgent
with two methods, ServingCellInformationChanged and Release.
This provides the list of available technologies in the radio-settings
atom. The list is queried by the DMS Get Capabilities method; ofono
takes care of caching the available technologies for us so we don't need
to worry about this method being called excessively.
call_status_to_string() is useful for debug output.
Change signature to contain enum call_status
Replace default case to get compiler warning when new enums added
The QMI radio-settings atom was just a skeleton and did not even implement
the mandtory property TechnologyPreference. As such, it probably should
never even have been registered for the modem. Nonetheless, this patch
puts this mandatory property into place.
This is implemented via the 'Set System Selection' method by way of the
'mode' parameter. This seems to best reflect the intention of the Ofono
API and works as expected when tested with a Quectel EC21.
Some notes:
i) There is an alternative function called 'Set Technology Preference'
which provides similar functionality. This 'technology preference'
is updated automatically when the 'system selection mode' is modified
so everything seems to be in order.
ii) For the EC21, switching the underlying technology works seamlessly.
There are indications, however, that some modems _might_ require a
reset before changes take effect; that bridge will need to be crossed
if reached.
Fix a warning.
