A new set of property+method is added to be able to configure the 5G
specific registration settings, initially defining the support for the
MICO mode.
The property name starts with "Nr5g" instead of "5gNr" because of the
limitations imposed by the GObject type system on how properties with
numbers can be named.
The udev flag "ID_MM_QMI_FACILITY_LOCK_QUERY_REDUCED" allows to skip
facility lock state query "get_ck_status" on the DMS path for devices
where this isn't implemented properly.
On devices that have enabled "device locks", this flag won't work well.
Skipping the query doesn't disable the locks.
Fixes#448
Main thing that's required to get modem hot-swapping to work is the
UDCONF=50,1 command(see u-blox AT-command manual). But there are a lot
of u-blox modules which do not support this command. So in this patch,
it's supposed that this thing is configured beforehand(Like the UUSBCONF
functioning mode) for modules, where SIM hot-swaping feature is
possible. For the modems where it's not, the patch will not have any effects.
----
For ublox modems, CIEV: 12(X) messages allow to know if
SIM is (un)plugged. The values are encoded as:
- 0: no SIM detected
- 1: SIM detected
It's required from a modem to generate these events about the SIM
detection state.
To set up these `CIEV: 12,(X)` URC events the `+CMER=1,0,0,1,0` command
is used. That command is supported by almost all u-blox modems except
SARA-G300/SARA-G310/LEON-G1(For these models the hot-swap feature will
not work).
As this 12 that is used in CIEV may be completely different in other
modules, the test command parsing is quite important to get that index
number. So, this logic is also added in cind_simind_format_check_ready
function.
----
It seems that it's necessary to issue this `+CMER` set up there despite
that the `+CMER` configuration will take place later in the 3GPP
interface enabling sequence. Because without it simind indications
will not be enabled at all.
CMER configuration may be later overwritten by 3GPP interface enabling
sequence, but in the worst-case scenario only hot-swap feature will not
work.
If we have a modem with an established connection, and then the
SIM is getting removed from that modem, this forces modem reprobing
sequence.
It looks like that:
```
mm-base-modem:mm_base_modem_process_sim_event
-> mm-base-modem:mm_base_modem_disable
-> mm-base-modem:disable
-> mm-broadband-modem:common_disable
-> mm-broadband-modem:disabling_step,
-> ctx->step=DISABLING_STEP_FIRST
-> ctx->step=DISABLING_STEP_WAIT_FOR_FINAL_STATE
-> ctx->step=DISABLING_STEP_DISCONNECT_BEARERS
```
At this stage, there is no actual connection existing already, but
bearer objects still exist and are still marked as connected.
So, if there were any active bearers - they will be disconnected.
In order to disconnect, ublox bearer sends +CGACT=0,%u, modem then
will return CME ERROR: 10(SIM not inserted):
```
[modem0/ttyACM0/at] --> 'AT+CGACT=0,1<CR>'
[modem0/ttyACM0/at] <-- '<CR><LF>+CME ERROR: 10<CR><LF>'
[modem0/ttyACM0/at] operation failure: 10 (SIM not inserted)
[modem0/bearer0] couldn't disconnect: SIM not inserted
```
this error will break disabling and reprobing. To fix that, it's
require to add 'SIM not inserted' state as a valid condition to
continue bearer disconnection.
By the time we report the bearer as 'Connected', the DBus client
should also be able to know right away the value of
'ReloadStatsSupported', instead of needing to wait for it to be
updated asynchronously.
This logic adds one additional step in the generic connection
sequence for this purpose, which is run after the modem is connected
but before we report the state change via DBus.
This property means that the current bearer can reload stats and read TX
and RX bytes transmitted.
The property is initiliazed as soon as the bearer is connected.

We originally did only 3 attempts every 3s, so the maximum probing
time for a given TTY port looking for AT capabilities was 9 seconds.
We now duplicate the amount of times, so up to 18s of port probing,
which is quite a lot more than before, but unfortunately it's needed
because most new modems take a lot of time to boot up internally.
The way to avoid this long probing time is to make sure port type
hints for the possible AT ports are set correctly.
Fixes https://gitlab.freedesktop.org/mobile-broadband/ModemManager/-/issues/379
The ModemManager codebase has been ported to support Basic Connect v3
messages as defined in MBIMEx v3.0, so at this point we can now switch
to use it by default whenever possible.
Whenever MBIMEx v3.0 is enabled, the logic should create requests and
parse responses using the updated format.
Based on an initial implementation by Som_SP <somashekhar.puttagangaiah@intel.com>

When an eSIM doesn't have any profile set, we should treat it as fully
ready to be used; i.e. so that a new SIM object can be created and
initialized.
In this state, the "eSIM status" property will say "No profiles".
Instead of running the Susbcriber Ready Status separately for IMSI and
ICCID, we run it only once and store the results in a new private
struct.
It only saves one request/response right now, but it will save more
once introduced other SIM parameters loaded with the same method.
The port type hints for the FM101 were updated to be in line with the final product layout,
where USB interface #2 is now used as an AT port (not ignored) and USB interface #4 is now
used as debug port. USB interface #6 is removed as it no longer exists.
The udev rules expect matches based on shell globbing pattern, not
based on regex. This means that "[0-9]*" doesn't mean "zero or more
digits", it actually means "one digit and zero or more other
characters".
So, avoid the regex like match, even if it worked for us, because it
didn't mean what we thought it meant, plus, it breaks our custom udev
rules processing logic, in which we convert the input patterns into
real regex expressions.
See https://bbs.archlinux.org/viewtopic.php?pid=1415916#p1415916
While at it, also make sure that the wildcard matching is done
exclusively for prefix and suffix matches, never in the middle of
a string, or our custom rules parser would not match correctly.
CDMA WAPs have multipart message information in a 3 byte header in-band
with the user data, as described in WAP-259-WDP-20010614-a. Set the
message concat parameters and use the message-id as the reference.
If the modem reports any error during the connection status check,
we're creating a GError but never disposing it. We don't need that
GError for anything, so just discard it.
Added scripts for Foxconn SDX55, Quectel EM120, and several old Sierra
Wireless manufactured devices:
* Installed but not used by default, the user needs to setup manual
links from ${pkgdatadir}/fcc-unlock.available.d, to
${pkgsysconfdir}/fcc-unlock.d in order to enable them.
* Installed with rights only for the owner, so that the dispatcher in
ModemManager can validate them.
* They rely on $PATH to find the qmicli/mbimcli tools.
In addition to these scripts, per-vid:pid links are created in the
same ${pkgdatadir}/fcc-unlock.available.d directory, specifying which
are the specific devices that require the FCC unlock operation.
This patch also creates the ${pkgsysconfdir}/fcc-unlock.d and
${pkglibdir}/fcc-unlock.d directories where ModemManager looks for the
enabled tools.
Note that the meson setup doesn't support creating/deleting links
officially yet, so we use a workaround using meson.add_install_script
that is not perfect (i.e. doesn't handle the symlink removal during
uninstall). See https://github.com/mesonbuild/meson/issues/1602
We remove the built-in FCC unlock procedures from the ModemManager, we
will no longer run them automatically, and instead rely on external
scripts/programs to do that.
Packages providing the external FCC unlock tools can install them in
${pkglibdir}/fcc-unlock.d.
Users manually enabling external FCC unlock tools can install them in
${pkgsysconfdir}/fcc-unlock.d.
The user-enabled path takes precedence over the package-enabled one.
MM was not processing NR5G signal strength for QMI signal info
response/indication message. Thus modem access technology and
signal quality was not reported for NR5G-only modems.
Process and consider NR5G signal strength too while getting
signal quality for modem interface.
As 5GNR does not have RSSI, take NR5G signal quality to be minimum
of percentage strength computed using RSRP, SNR and RSRQ values
individually.
MM was not processing NR5G service info for QMI system info
response/indication message. This led to NR5G-only modems never
having 'registered' status.
Process NR5G system info and accordingly update the 5gs
registration status for qmi modems.
This commit also removes some stale comments.
