This interface allows devices to provide location information to client
|
|
applications. Not all devices can provide this information, or even if
|
|
they do, they may not be able to provide it while a data session is
|
|
active.

When enabling location information gathering, this argument controls
|
|
whether the device emits signals with new location information or not.
|
|
When signals are emitted, any client application (including malicious
|
|
ones!) can listen for location updates unless D-Bus permissions
|
|
restrict these signals from certain users. If further security is
|
|
desired, this argument can be set to FALSE to disable location
|
|
updates via D-Bus signals and require applications to call
|
|
authenticated APIs (like GetLocation) to get location information.
|
|
This argument is ignored when disabling location information
|
|
gathering.

|
|
<p>For capability reporting, indicates the device is capable of
|
|
providing GPS NMEA-format location information.</p>
|
|
|
|
<p>For location reporting, devices supporting this capability return
|
|
a string containing one or more NMEA sentences (D-Bus signature 's').
|
|
The manager will cache the most recent NMEA sentence of each type for
|
|
a period of time not less than 30 seconds. When reporting multiple
|
|
NMEA sentences, sentences shall be separated by an ASCII Carriage
|
|
Return and Line Feed (<CR><LF>) sequence.
|
|
</p>
|
|
<p>
|
|
For example, if the device sends a $GPRMC sentence immediately
|
|
followed by a $GPGGA sentence, the reported location string would be
|
|
(where of course the <CR><LF> is replaced with the actual
|
|
ASCII CR (0x0D) and LF (0x0A) control characters):
|
|
<pre>
|
|
$GPRMC,134523.92,V,,,,,,,030136,,,N*73<CR><LF>$GPGGA,,,,,,0,00,0.5,,M,0.0001999,M,0.0000099,0000*45
|
|
</pre>
|
|
If the device sends a new $GPRMC three seconds later, the new $GPRMC
|
|
replaces the previously received $GPRMC sentence, and the updated
|
|
string would be:
|
|
<pre>
|
|
$GPRMC,134526.92,V,,,,,,,030136,,,N*76<CR><LF>$GPGGA,,,,,,0,00,0.5,,M,0.0001999,M,0.0000099,0000*45
|
|
</pre>
|
|
If the device then sends a $GPGSA sentence about 5 seconds later, the
|
|
$GPGSA sentence is added to the string (since no $GPGSA sentence was
|
|
previously received in this session), the updated string would be:
|
|
<pre>
|
|
$GPRMC,134526.92,V,,,,,,,030136,,,N*76<CR><LF>$GPGGA,,,,,,0,00,0.5,,M,0.0001999,M,0.0000099,0000*45<CR><LF>$GPGSA,A,1,,,,,,,,,,,,,1.1,0.5,1.0*34
|
|
</pre>
|
|
The manager may discard any cached sentences older than 30 seconds.
|
|
</p>
|
|
<p>This allows clients to read the latest positioning data as soon as
|
|
possible after they start, even if the device is not providing
|
|
frequent location data updates.

<p>For capability reporting, indicates the device is capable of

|
|

|
<p>For location reporting, devices supporting this

|
capability return a string in the format "MCC,MNC,LAC,CI" (without the
|
|
quotes of course) where the following applies:</p>
|
|
<ul>
|
|
<li>
|
|
MCC is the three-digit ITU E.212 Mobile Country Code of the
|
|
network provider to which the mobile is currently registered.
|
|
This value should be the same MCC as reported by the
|
|
org.freedesktop.Modem.Gsm.Network.GetRegistrationInfo() method's
|
|
returned "operator code" argument.
|
|
e.g. "310"
|
|
</li>
|
|
<li>
|
|
MNC is the two- or three-digit GSM Mobile Network Code of the
|
|
network provider to which the mobile is currently registered.
|
|
This value should be the same MCC as reported by the
|
|
org.freedesktop.Modem.Gsm.Network.GetRegistrationInfo() method's
|
|
returned "operator code" argument.
|
|
e.g. "26" or "260"
|
|
</li>
|
|
<li>
|
|
LAC is the two-byte Location Area Code of the base station with
|
|
which the mobile is registered, in upper-case hexadecimal format
|
|
without leading zeros, as specified in 3GPP TS 27.007 section
|
|
10.1.19. e.g. "84CD".
|
|
</li>
|
|
<li>
|
|
CI is the two- or four-byte Cell Identifier with which the mobile
|
|
is registered, in upper-case hexadecimal format without leading
|
|
zeros, as specified in 3GPP TS 27.007. e.g. "2BAF" or "D30156".
|
|
</li>
|
|
</ul>
|
|
<p>The entire string may only be composed of the ASCII digits [0-9],
|
|
the alphabetical characters [A-F], and the comma (,) character. No
|
|
other characters are allowed. For example: "310,260,8BE3,2BAF" or
|
|
"250,40,CE00,1CEAD8F0".</p>
|
|
|
|
<p>If any of these four items (MCC,MNC,LAC,CI) is unknown or the
|
|
mobile is not registered with a network, then the GSM_LAC_CI location
|
|
information item should not be provided as a returned value from the

GetLocation() method or in the Location property.</p>
