The new PHS8 or PXS8 devices may expose multiple tty ports, but only one is
supposed to be used for PPP. So, query which port that is and flag it before
grabbing it in the modem.
This patch modifies MMBroadbandBearerHuawei such that connect_3gpp
simply reports an error via g_simple_async_report_error_in_idle, without
creating a Connect3gppContext, if no data port is available.
This patch prevents connect_3gpp_context_complete_and_free from calling
'g_object_unref (ctx->data)' when connect_3gpp finds no data port (i.e.
ctx->data is set to NULL).
The Novatel LTE modem only uses its primary AT port for AT commands.
Instead of referencing any existing secondary port, this patch changes
MMBroadbandBearerNovatelLte to explicitly use the primary port during the
connection and disconnection sequence.
The Altair LTE modem only uses its primary AT port for AT commands.
Instead of referencing any existing secondary port, this patch changes
MMBroadbandBearerAltairLte to explicitly use the primary port during the
connection and disconnection sequence.
This patch fixes mm_huawei_parse_prefmode_test to always report an error when
returning NULL, which avoid a potential crash when the caller tries to access
the error.
Some Huawei modems (e.g. E220) may give an empty response for AT^SYSCFG=?, even
if they do support the command. Handle this case by prividing a default fallback
format string when this happens.
On at least the EC168C, various unsolicited responses like RSSILVL,
HRSSILVL, and MODE can include an extra Carriage Return:
^MODE: 2<CR><CR><LF><CR><CR><LF>
^RSSILVL:60<CR><CR><LF><CR><CR><LF>
A firmware bug in Altair ALT3100 bricks the modem when
- The modem is out of coverage (Registration state is unknown (CEREG: 4))
- A disconnect attempt is made using the AT%DPDNACT command.
This patch prevents this situation by failing the connect/disconnect attempts in
the altair plugin when registration state is unknown, without attempting to
connect/disconnect the modem.
As soon as we get a match between the current interface being probed, and the
first expected interface to probe, clear the timeout. But this doesn't mean that
this interface being probed will be the correct one, so it may be the case that
we end up expecting a new first interface and probing another one.
With an example probably seen better...
Modem appears with interfaces 2, 3 and 4.
1. We first try to look for interface 0, which is not in the set:
1.1. Probing interfaces 2, 3 and 4 get deferred.
2. First-interface timeout happens because interface 0 doesn't appear, so we
switch to wait for interface 1:
2.1 Probing interfaces 2, 3 and 4 get deferred.
3. First-interface timeout happens because interface 1 doesn't appear, so we
switch to wait for interface 2:
3.1. We get a match on interface 2, which exists. We now remove the
first-interface timeout and start running the init sequence there.
3.2. Probing interfaces 3 and 4 get deferred.
4. Init sequence in interface 2 fails, because it is not an AT port, so we
switch to wait for interface 3:
3.1. We get a match on interface 3, which exists. We do *not* need to remove
now the first-interface timeout because this interface we are testing is
actually the second one which we tried.
So, just check whether the timeout exists or not, and if it exists remove it.
Yeah, this commit just fixes a warning at the end.
If a client-initiated disconnection attempt is issued while a
network-initiated disconnection is still pending, the latter may
interfere with the former. Also, when the client-initiated disconnection
attempt fails but the bearer status is reported as 'disconnected', the
pending network-initiated disconnection is not cleared and may result
in an assertion when a connection attempt is issued.
This patch addresses the issue by clearing any pending network-initiated
disconnection before proceeding with a client-initiated disconnection.
The original sysinfoex_parse() in MMBroadbandModemHuawei does not handle
unquoted <sysmode_name> and <submode_name> fields in ^SYSINFOEX responses,
which are sen on some Huawei modems (e.g. E303). This patch moves the
^SYSINFOEX parsing code to mm-modem-helpers-huawei.c, fixes the regex for
handling unquoted strings in ^SYSINFOEX responses, and adds unit tests.
