Parameter description

Notes
•
To get the distance that the device has covered (e.g. during a trip), firstly
reset the distance to zero using
$PFAL,GPS.Nav.Distance=0
(
see next section)
and when the destination point of the trip is reached, simply request the
driven distance using
$PFAL,GPS.Nav.Distance
.
•
If you reset the device during the trip, the covered distance will be set to zero.
3.2.4.1.6
GPS.Nav.Distance=
<value>
– Sets/resets the distance to a user value
Command syntax
$PFAL,GPS.Nav.Distance=<
Examples
$PFAL,GPS.Nav.Distance=
0
$PFAL,GPS.Nav.Distance=
10
Responses
Command description
This command resets the distance to a user-defined value, which may represent
either a new start point or the distance tolerance from where a trip starts.
Parameter description
<value>
Integer type value in the range
0
to
2147483647
.
Notes
•
Each value sent to the device overwrites the existing value.
3.2.4.1.7
GPS.Nav.SaveLastValid – Saves the last valid position, if no GPS-fix
valid
Command syntax
$PFAL,GPS.Nav.SaveLastValid
Examples
$PFAL,GPS.Nav.SaveLastValid
Responses
E.g. $last valid position saved to configration
Command description
If MAMBOII is currently receiving invalid GPS position data, an empty RMC message
will be stored (RMC data containing only zero values). To prevent storing of this
invalided GPS data, utilize this command as an alarm
(
AL2=Sys.Device
.eShutdown
:
GPS.Nav.SaveLastValid
) to store the last valid position
to non-volatile memory before the MAMBOII device goes to sleep. This data stored
in non-volatile memory will be needed on the next power up scenario. If during the
next start-up scenario there is no valid GPS fix, the stored last valid position will be
automatically attached to
“
MSG.Info.Serverlogin
“
command and sent to the
remote server. In this way you always receive valid GPS position instead of a RMC
protocol containing only zero values (if the device has an invalid GPS-fix after start-
up, only).
Parameter description
none.
Notes
•
Due to the non volatile memory is limited to several 100'000 write operations, it
is strongly recommended to prevent periodically saving of last valid position in
a short amount of time.
