Some quectel devices, like the EC25 have a non-standard additional '3'
mode value:
0: Disable automatic time zone update via NITZ
1: Enable automatic time zone update via NITZ
3: Enable automatic time zone update via NITZ and update LOCAL time to RTC
In preparation for the multi-SIM setup, we need a way to tell whether
a given SIM card is active or not in the system.
On systems with one single SIM slot, the available SIM card will
always be active.
On Multi-SIM Single-Standby setups we may have multiple SIM slots with
multiple SIM cards, but only one of them will be active at any given
time.
On Multi-SIM Multi-Standby setups we may have multiple SIM slots with
multiple SIM cards that may be active at the same time. E.g. the QMI
protocol allows up to 5 different active SIM cards (primary,
secondary, tertiary...).
There was a limitation in the past in the plugin, because one of the steps
during the dial (CONNECT_3GPP_CONTEXT_STEP_PDP_CTX) was to reconfigure a
specific CID hardcoding the IP type to IPv4.
That logic was removed in commit af2d6c1c4b,
but we didn't remove the IPv4 limitation at that point.
some ITM family modems require full parameters:
AT^SGAUTH=cid,type,user,pwd
even when type is AUTH_NONE.
Fortunately, all modules of the IMT family tolerate this syntax,
so it can be adopted for the entire family.
the AT^SCFG="Radio/Band" command does not return a different answer
for different charsets.
This code was working previously because the charset was left to default (GSM)
at the time of this operation, and therefore the string was unchanged anyway.
CHAP is almost universal nowadays, and so it is a better default
than PAP
Not changed for uBlox, that prefers an error if not specified,
and for Huawei, which uses NONE with user/pwd and has 2 CHAP choices
The ELS61 doesn't like authentication given without quotes:
[modem3/ttyACM1/at] --> 'AT^SGAUTH=8,1,tm,t-mobile<CR>'
[modem3/ttyACM1/at] <-- '<CR><LF>+CME ERROR: 4<CR><LF>'
Only when user/pass strings are quoted it works:
[modem6/ttyACM1/at] --> 'AT^SGAUTH=8,1,"t-mobile","tm"<CR>'
[modem6/ttyACM1/at] <-- '<CR><LF>OK<CR><LF>'
It's critical not to timeout early on devices with AT ports, or we may
end up flagging the modem as invalid.

Extended the ModemManager Signal interface to include 5G signal
information for RSRP, RSRQ and SINR via libqmi. Also extended mmci
to print 5G signal info.
While at this change also the previous generic reference to ME910
in order to differentiate between ME910C1 (based on MDM9206) and
MEx10G1 (based on MDM9205).
If any enabling/disabling command fails, we consider the operation
failed, regardless of the QGPS status. This is because e.g. enabling
involves more operations than just QGPS=1, and so we should treat a
failure in the command sequence as a failure in the whole operation.
The method that reports what location capabilities are supported must
report the capabilities provided by the parent interface plus the
additional capabilities supported by the shared implementation.
Also, simplify the logic a bit reducing the amount of implemented
methods.
Instead of using the FALSE return of the method to indicate either a
fatal error (if result_error was set) or the continuation request (if
result_error wasn't set), provide a enum that has explicit states for
all three possible values (failure, success or continue).
Instead of setting up the ID_MM_TTY_BLACKLIST tag used in 'legacy'
filter mode, tag all known u-blox GPS devices with the broader
ID_MM_DEVICE_IGNORE tag that applies under all filter modes.
Also, make this rules be installed by the plugin itself, because at
the end, it is the u-blox plugin the one attempting to probe all
devices with vid 0x1546.
