This method allows deflecting an incoming or waiting call to a
different number.
|
|
|
|
This method will join all active and held calls into a single
multiparty call, and then request the network to terminate the call on
the subscriber's end and transfer the control of the call to the
parties that are still in the call.
|
|
|
|
This method will terminate all ongoing calls.
|
|
|
|
This method will put the currently active call on hold, and right away
accept the next available call.
The user of the API does not need to specify explicitly which is the
next call to accept, because that is decided automatically:
* If there is any waiting call, it will accept it right away.
* If there is no waiting call but there is a held call, it will make
the held call active again.
|
|
|
|

E.g. we can hangup a waiting call without interfering with the active
one.

Early detect that ^SLCC is supported, and disable the call list
polling in the interface if so.
|
|
If the modem supports call list polling, we'll setup a timeout to poll
for the full call list periodically, in order to get detailed call
states.
The timeout is setup as soon as a new call is created, and it will be
kept enabled as long as there is a call being established (i.e. not
unknown, not terminated, not active).
|
|
|
|
|
|
This command will give us URCs whenever the extended list of current
calls changes, which includes information about the actual state of
each call, even for calls in waiting state.
Therefore, as this is a URC that applies to all calls, it's enabled
and disabled as part of the modem voice interface, instead of doing it
as part of the call object itself (i.e. not treated as an in-call URC).
|
|
|
|
The first two ports are AT control ports (application/modem). We rely
on AT^SQPORT to decide which one is which.
The last two ports are unknown and we explicitly ignore them to make
port probing much quicker.
|
|
E.g. as per the AT+CLCC output.
|
|
|
|
|
|
E.g. if the modem supports reporting incoming call updates explicitly.

The previous logic would end up returning an error if either +CLIP or
+CRC reported an error, and we should really avoid that, because our
setup is able to manage the voice calls even without those settings.
So, convert the logic into a small state machine and try to configure
the settings both in the primary and secondary ports, instead of just
in the primary one.

This CL converts a few g_regex_match_full() expressions to their
equivalent g_regex_match() in order to simplify the code, i.e.
g_regex_match_full (regex, str, strlen (str), 0, 0, &match_info, NULL)
is equivalent to:
g_regex_match_full (regex, str, -1, 0, 0, &match_info, NULL)
or simply:
g_regex_match (regex, str, 0, &match_info)

The operation sending the raw data of the SMS may timeout because the
current value of 10s is too low.
When this happens, we may end up marking the modem as invalid if the
operation takes much longer, as in

The regex was expecting empty values in several of the fields, which
is wrong. Instead of matching empty fields, just ignore all fields
that we don't require in our logic.

The custom +CIEV parser configured for Cinterion modems was
exclusively matching the "psinfo" indicator updates, which were the
ones really used afterwards.
But, in order to avoid having undesired URCs mixed with other command
responses, we should anyway match any +CIEV indicator reported, not
only "psinfo".
The text indicator ids used in +CIEV seem to bee specific to Cinterion
devices when they're configured via AT^SIND, so we do a generic match
for any lowercase ascii text as indicator id.

If load_current_bands_finish() returns a NULL GArray, we must set the
GError or otherwise the daemon will segfault when the caller
dereferences the GError:
current_bands = MM_IFACE_MODEM_GET_INTERFACE (self)->load_current_bands_finish (self, res, &error);
if (!current_bands) {
/* Errors when getting current bands won't be critical */
mm_warn ("couldn't load current Bands: '%s'", error->message);
g_error_free (error);
}
This may happen with an empty but balid +UACT response, e.g.:
AT+UACT?
+UACT: ,,,
OK
Or when it replies a full empty string:
AT+UACT?
OK

We use the raw commands exclusively when we're sending SMS data to the
device. Until this change, all raw commands were added at the tail of
the queue of pending commands, and that meant that if any unrelated AT
command was interleaved between e.g. our AT+CGMS and the actual SMS
data sent, the operation would have failed.
With this fix, we're making sure that all raw commands are added at
the head of the queue, so we're making sure that the next command
picked after e.g. CGMS is actually the raw SMS data to be sent.
We would be avoiding issues like this one, where an outgoing voice
call attempt gets in the way before we send the SMS data:
[1556246081.786284] (ttyACM2): --> 'AT+CMGS=70<CR>'
[1556246081.814861] (ttyACM2): <-- '<CR><LF>> '
[1556246081.819382] (ttyACM2): --> 'ATD1234567890;<CR>'

[1556246081.922470] (ttyACM2): <-- '<CR><LF>+CME ERROR: 4<CR><LF>'
|
|
By default all the commands we were sending through the serial port
were added at the tail of the pending queue, but we may want to queue
them at the head in very specific cases (e.g. while sending an SMS).
