For CLID=3 when GPS is invalid any event that generates a report or a reply to $POLL or
$POSN will cause the location to be requested from the GSM network, but only if the last
request was more than <request_period> minutes ago. The status in the report will
indicate that the location is network based in addition to invalid GPS.

OTA Programming PIN Code (PASS)
OTA PIN code feature, which can be used to prevent unauthorised reconfiguration by
SMS. The PIN code is specified using the PASS command. The PASS code can be set by
RS232, SMS or TCP mode commands, but if PASS is non-zero, the correct current PASS
code must be supplied before the new value. By default, PASS is set to zero, which
disables OTA PIN code requirement. If PASS is set to any other value, the correct value
must be specified with each OTA command. The PASS parameter must be the first
command in the sequence.
e.g.
to change distance reporting, when current PASS code is set to 12345:
$PASS,12345$DIST,1500
e.g.
to change PASS code from 12345 to 5678:
$PASS,12345$PASS,5678
Only commands which change parameters require the PIN code. The PIN code is never
required for the following commands: $ATSW, $BOOT, $DIAG, $IMEI, $NACK, $PARA,
$POLL, $POSN, $SDIG, $SHDN, $SHOW, $SSMS and $STAT.
Geofences (GEOF)
Device based geofences can be configured with the GEOF command, which has 5
arguments as follows:
$GEOF,<index>,<type>,<radius>,<latitude>,<longitude>
Field
Description
Range
<index>
index
1 - 100
<type>

<latitude>
latitude, WGS84 decimal degrees
-90.0 to +90.0
<longitude> longitude, WGS84 decimal degrees
-180.0 to +180.0
Entering the command with index argument only will echo back the existing geofence
settings.
