It was actually included in the man page of the daemon, but we didn't have it.
|
|
The MF60 exposes a QMI+net pair, but they are unusable as the WDS service
returns error when e.g. launching a connection.
So, fallback to AT+PPP in this device.
|
|
The new 'ID_MM_PORT_IGNORE' tag will tell ModemManager to fully avoid using a
given port.
Note that it is key to not only flag the port probe as ignored, but also to
fully ignore the ports in e.g. mm_port_probe_list_has_qmi_port() as those
methods will be used to decide which kind of modem object to create. We don't
want to create a QMI-based modem which may have all QMI ports blacklisted.
|
|
E.g. this would be the result when having ModemManager compiled without QMI
support, and a modem with 2 QMI/WWAN pairs:
$ mmcli -m 2

The /dev/cdc-wdm ports don't even appear (as they were not even probed), but the
newly ignored WWAN ports do appear in the list, but flagged as UNKNOWN type
(instead of NET).

Modems may expose ports that are either just not used (e.g. modems exposing more
than 2 functional AT ports) or explicitly avoided (e.g. WWAN ports when we don't
know how to use them).
Those kind of ports are part of the modem, but not used by ModemManager. Still,
ModemManager should list them in the list of ports available for the modem, with
IGNORED type.

Some newer modems (Huawei E1750, Sierra 73xx) provide what looks like
legitimate static IPv4 configuration through the WDSGetCurrentSettings
call, but when configured the interface does not pass traffic. Running
DHCP on the same interface provides a slightly different IPv4
configuration but does allow traffic to pass.
Since QMI was switched to static originally for consistency with IPv6
and for speed of IP configuration (since DHCP takes a bit of time), but
not for any known problems with modems, let's switch back to DHCP until
we have time to figure out what's actually going on.

Third revision of Huawei nwtime support. Takes on feedback from the
mailing list including helpers, some basic tests and use of the ^NTCT
command to determine network time support (^NWTIME). Expanded test cases,
more use of g_assert and more logical helper return values/errors.

We have a report of a modem that switches access technologies frequently,
in this case almost every 10 seconds. While that's unusual, it's not
unexpected depending on the RF environment. We shouldn't spam syslog
with that info; if we need it we can get it with mmcli.
|

We were depending on some new MbimNwError values defined at some point in the
1.9 development series. Depend on the new stable 1.10 version now that it's been
released.
|

|
|
So, we may have modems with multiple /dev/cdc-wdm ports, like Ericsson modems,
where only 1 of them is MBIM. With the previous logic, we would probe all
/dev/cdc-wdm ports for MBIM as soon as one of the ports was handled by the
cdc_mbim driver. That is totally not optimal, as we are already know that they
are not MBIM (not handled by cdc_mbim).
Instead, fix the logic to just probe for MBIM or QMI if the actual driver
managing the port is MBIM or QMI.

It's been observed that some modems occasionally take a long time to
power down (which may be due to some shutdown sequence that involves
communicating with network). This patch increases the timeout for
powering modem up and down from 10s to 20s.
|
|
It's been observed that modems may take a long time to disconnect from
the network under certain network conditions. This patch increases the
timeout for the MBIM_CID_CONNECT set command in the disconnect sequence
from 10s to 30s.

VID/PID: 258d:e000
Instead of returning success and the PIN type + PIN status + Remaining attempts,
this modem returns a plain ERROR_PIN_REQUIRED error, so try to handle that...

Just so that we don't have same header names in src/ and /libmm-glib.

Just like 'modepref', but not doing any mode changes, just OFFLINE+RESET.

Implement GPS support on the MU609 and MU090 Huawei modules.
Its highly likely the commands are the same for other Huawei modems
and it just needs to be activated via udev rules that flag the GPS port
with ID_MM_HUAWEI_GPS_PORT=1.
There are a lot of options that can be tweaked on the Huawei GPS setup,
this code just chooses a simple default for unassisted, standalone GPS
operation.

Standard GPS setup (raw/nmea) will both enable the GPS module and take full
control of the GPS port. This prevents other processes from reading the NMEA
traces from e.g. a tty. In order to handle this, a new 'unmanaged' GPS location
source is introduced, which will just enable/disable the GPS module, without
reading anything from the GPS port. Of course, both raw/nmea and unmanaged
setups cannot be enabled at the same time.
|
|
|
|
The PHS8 in QMI-mode doesn't support GPS location retrieval via QMI, so we will
fallback to use the AT-based setup and the TTY for reading NMEA traces.
|

As they all use the 'MMSimpleStatus' type.

The MU609 modems from Huawei have a bug (confirmed by Huawei) that causes
the modem to reset if AT^GETPORTMODE is issued.
I have provided and example udev rule I use to disable this command as a
patch, feel free to drop that if its not acceptable. Since I cannot tell
the modem type from within the udev rules this is less specific than my
previous code based patch, but much simpler ;-)
I have two modems that share the same USB ID, however, neither supports the
^GETPORTMODE command (and one of them crashes when it is issued). Perhaps
someone with a Huawei that supports ^GETPORTMODE can check their USB ID's
and see if they clash.
Here is a comment from the Huawei devs:
> We confirmed this is a issue. This is Qualcomm baseband command at Data
> Card. We didn’t delete and block it. We will fix this issue in next FW.
> Thank you very much.

This enables support for GPS location reporting when the PHS8 is NOT used in QMI
mode.
|
|
We shouldn't rely on the caller to cleanup intermediate results when returning
an error.
|
|
Allow whitespaces added in several places, like between the comma and the index,
which is what the Cinterion PHS8 does:
<CR><LF>+CMTI: "MT", 5<CR><LF>
