REPORT_POSITION. If the device had been unable to compute a new position
fix since the most recently logged REPORT_POSITION, and there has been
recent motion, then the new STATUS_MESSAGE will have the Position Age flag
set to “1=Aged”.
Enabling this Scheduled Report Mode has the added benefit of the server
application knowing when the device will be connected to the GSM network. As
such, the server application could send messages in anticipation of the TrimTrac
ProE being connected to the GSM network at the designated time. This is
particularly useful if the TrimTrac ProE is expected to be off the GSM network
for an extended period of time due to either being out of coverage or due to lack
of motion and long IDLE Timeout, T1, settings. Some GSM network operators
may delay when messages or data packets get delivered to mobile devices when
the mobile device has not been connected to the network for an extended period.
Note that this feature can not be used to force the TrimTrac ProE to report at fixed
intervals other than daily or weekly.
Polling
Polling on the TrimTrac ProE has been implemented somewhat differently than
earlier generations of the TrimTrac locator. Polling can be implemented on the
TrimTrac ProE either based upon motion or regardless of motion. In order to
enable polling, the TrimTrac ProE remains connected to the GSM network in
states other than just the TRANSMIT or QUERY states. Connection to the GSM
network requires that the device keep the internal GSM modem powered up and
operating. This, of course, increases power consumption and reduces battery life,
but the ability to more continuously communicate with the device may outweigh
these negative side effects.
