Sending Reports Automatically
Remote
You can configure the AirLink device to send reports based on a time interval and
on the movement of a vehicle (based on it’s position from one time to the next).
• *PPTIME - Location report sent every set time interval (seconds).
• *PPDIST - Location report sent only if the position is more than the set
distance (x 100 meters).
• *PPTSV - Location report sent if the vehicle has been in one location
(stationary) for more than a set time interval (minutes).
• *PPMINTIME - Location report sent be sent at no less than this time interval
(seconds).
Note: If you’re implementing both a time interval and distance interval for reports, the
AirLink device will use the timer which expires first. The reporting interval can impact your
data usage. If the interval is set frequently, you may want to have a high usage or unlimited
data plan.
Tip: One mile is approximately 1600 meters. 1000 meters is one kilometer.
Local
If you are sending reports on the local serial port, and/or if you want them sent
automatically, you will need to set *PPLATS. The time interval, just as for
*PPTIME, is in seconds.
Store and Forward
Store and Forward can provide seamless coverage even in areas with intermittent
cellular coverage. If the AirLink device leaves coverage or has very low signal (an
RSSI of -105 or lower), it will store the GPS messages in memory. When the
modem re-enters cellular coverage, it will then forward the messages as
configured. The AirLink device can also store messages and send them to the
server in a packet rather than individually to conserve bandwidth.
Enable Store and Forward using *PPSNF. You can also determine how you want
the messages sent using *PPSNFB and *PPSNFM.
• Normal - Each report is sent immediately.
•Polled - Reports held until requested by the server.
• Grouped - Reports held until the total is equal or greater than *PPSNFM
which sets the packet size of grouped reports.
