When the modem is in a failed state because of a SIM-related error,
like a missing SIM, or if the modem is SIM-locked, allow the
Location interface to initialize and be enabled anyway.
This allows someone without a SIM to use the GPS, which does not
particularly require a phone subscription. It also allows
someone with a SIM to use the GPS even if the SIM is still
locked.
This patch was reworked, while keeping the original idea, by:
Aleksander Morgado <aleksander@aleksander.es>
Fixes #183

Multi-sentence NMEA messages were printed as is, that is with
linebreaks, which made mmcli --location-get output look broken.
Split NMEA sentences with linebreaks to separate output list items, so
that they line up correctly.
|
|
This action allows us to monitor location updates as signaled via the
'Location' property, only available if location signaling has been
explicitly enabled (e.g. with --location-set-enable-signal)

TAC is 3 bytes for NG-RAN as specified in 3GPP TS 38.413 clause
9.3.3.10 and in 3GPP TS 24.501 clause 9.10.3.8.
We'll always print it as 3 bytes in the cli output, as that's also
backwards compatible with the original 2 byte TAC in LTE.

So that --help-all print all sections in the same way as the Help and
Application option groups.

The A-GPS based implementations we currently have assume MSA A-GPS, so
rename the MMModemLocationSource enum value to reflect that.
|
|
|
|
In addition to the standard human-friendly output, we now allow a
machine-friendly key-value pair output, much easier to parse and use
by programs that look at the mmcli output.
This new key-value pair output should be treated as API from now on, so
third-party programs can assume the output is compatible from one
release to another.
|
|
The --location-get action provides full location information from all
sources, which is better than per-source actions, as those were anyway
using the same API method to load location information as the global
one.

Remove the redundant declaration of which slipped into the code in commit
091bf4dbd811 ("api: support location assistance data").

All these values are usually specified in hex, not in dec.

Devices will expect SUPL server given as either IP:PORT or FQDN:PORT,
so just avoid saying we require a 'URL' because it's not true.
We will use a new helper method to parse and validate user-provided
SUPL server address.
|
|
Sometimes SUPL-server based A-GPS is not possible, e.g. if the module
doesn't have Internet connectivity. In such cases, the modem may
support injecting additional "assistance data" that may be downloaded
from the Internet using external means (e.g. WiFi), in order to keep
having a quick time to first fix.
We now support using this location assistance data, with the following
new API elements:
* A new mask of supported assistance data types is provided in the
SupportedAssistanceData property.
* A new list of URLs from where the aassistance data may be
downloaded is also provided in a new AssistanceDataServers
property.
* A new InjectAssistanceData() method is provided, to perform the
data injection in the module once it's been downloaded to the host
system.

The "location area code" field is given in GSM/UMTS networks
exclusively. LTE networks use the concept of "tracking area code"
instead.
This patch updates the Location interface to Provide separate fields
for LAC and TAC, instead of giving TAC values in the LAC field.
|
|
|
|
Not making them '--location-enable|disable-signal' because that's the pattern
used to enable/disable location sources. Instead, use the '--location-set-*'
pattern, as that is what we're already using for the other location setup
update.
|
|
The default setup uses a refresh time of 30s, which means that even if the GPS
location updates are received at a higher frequency, the DBus interface will
still expose at most one update every 30s.
This patch includes a new "SetGpsRefreshTime()" method in the Location
interface, which takes a single 'u' parameter, specifying the refresh rate to
use, in seconds. This method also allows 0 being passed, which will make the
implementation to publish the GPS location updates are soon as ModemManager
detects them.
Along with the new method, a "GpsRefreshTime" read-only property is exposed
to specify the refresh time in effect.
The new method and property will only be applicable if the device has GPS
capabilities.

mmcli is GPLv2+; that's what --version has always said and that's what the
README in ModemManager sources specifies:
License.
The ModemManager and mmcli binaries are both GPLv2+.
The libmm-glib library is LGPLv2+.

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.
|

Both the ModemManager daemon and the mmcli will now include `libmm-glib.h' only.
We also handle two new special `_LIBMM_INSIDE_MM' and `LIBMM_INSIDE_MMCLI'
symbols, which if included before the `libmm-glib.h' library allow us to:
* Don't include the libmm-glib high level API in the ModemManager daemon, as
the object names would clash with those in the core.
* Define some of the methods of helper objects to be included only if compiling
ModemManager daemon or the mmcli.

By default 30s will be used for every operation.
|
|
Don't rely on the lock status, as the modem may say it requires SIM PIN 2, but
we're allowed to run most operations even with that unlock required.
|
|
|
|
|
|
For example, we do allow:
mmcli -m 0 --enable-location-gps-nmea --disable-location-gps-raw
All the options get merged into a single Setup() call in the Location interface.
|
|
|
|
|
|
Location sources can now be enabled or disabled by using the mask of sources
given in Setup() (similar previous Enable()).
|
|
Do not try to perform feature/capability specific actions if we're still
unlocked, as the modem didn't yet export the feature/capability specific
interface.
The only interfaces expected while modem is unlocked are the Modem and Simple
interfaces, as well as the SIM interface in the SIM object, of course.
|
|
Renamed `MMCommonLocation3gpp' to `MMLocation3gpp', and removed the
`MMModemLocation3gpp' provided in libmm-glib. We'll just use the original one
from libmm-common always.
