This library will not (probably) be installable, but will share the GDBus
and new Enum/Flag/Error type support between the core daemon and the new
libmm-glib library.
Keep the Bearer interface out of the 'Modem' subtree in the interface hierarchy,
as it will be specific for Bearer objects, not implemented by Modem objects.
Keep the SMS interface out of the 'Modem' subtree in the interface hierarchy,
as it will be specific for SMS objects, not implemented by Modem objects.
The Scan() method returns an array of dictionaries, where each dictionary is
defined by a string key plus a variant data (not a string data). This is to
handle the "status" and "access-tech" entries, which are given as unsigned
integers.
Make port roles more flexible. We have modems that do PPP
on interfaces other than the primary interface, and that
wasn't possible with the old code. So clean up all that
logic and move the port organization code into the core
so we can reduce code in the plugins.
In the new world order, the plugins say whether the port
is a QCDM port, an AT port, or ignored. If it's an AT
port the plugins get to tag it as primary, secondary, or
PPP, or any combination of the 3. This allows for modems
where PPP should really be done on the secondary port
(Huawei E220, Sierra devices) so that the primary port
stays open for command and status.
Modem subclasses no longer get asked to handle port grabbing
themselves. Instead, that's now done by the generic classes
(MMGenericCdma and MMGenericGsm) and the plugins are notified
when a port is grabbed so they can add unsolicited response
handlers for it. After all ports are grabbed by the generic
classes, they get "organized", which assigns various ports
to the roles of PRIMARY, SECONDARY, DATA, and QCDM based
on specific rules and hints that the plugin provided (which
are expressed as MMAtPortFlags). The plugins then have
a chance to perform fixups on the primary port if they choose.
The plugin code is responsible for determining the port
hints (ie MMAtPortFlags) at probe time, instead of having
a combination of the plugin and the modem class do the
job. This simplifies things greatly for the plugins at
the expense of more complicated logic in the core.
Seems that launching AT+CSQF when not registered ends up timing out. AT+CSQF
is meant to be the fast version to get the signal quality, and is expected to
return instantly with the last cached signal quality value. But if we never
got registered, there is no such cached value, so it probably waits to get the
first one.
We must send ATZ alone and once reply received, wait some time before sending
the next initialization commands. Otherwise, the next commands will receive
garbage as reply. The only way to handle this is to override the whole generic
initialization phase.
We will also avoid sending any power-up command, as not needed.
