DRAFT TrimTrac 1.5 Technical Manual v0.3ab 9
This mode causes the TrimTrac 1.5 to compute and transmit one position report
upon first motion and one position report after coming to rest. There are no
reports transmitted in between even though the device may be logging, but not
transmitting, positions in the background. This provides a historical log that
could be queried should the need arise while minimizing communication costs in
the mean time. How long the device must remain at rest before transmitting the
stop report is determined primarily by the DELAY Timeout, T4. (See Report
Delay Flag settings in AT+CTKC on page 83; SET_APP_CONFIG on page 113)
Automatic Message Log Dump
When GSM coverage becomes available after a period of no coverage, the
TrimTrac 1.5 can be configured to transmit messages that would have otherwise
been transmitted had GSM coverage been uninterrupted. This feature would be
used when the TrimTrac 1.5 is expected to come in and out of GSM coverage
areas and it is important for the server application to know where the device has
been regardless of GSM availability. (See AT+CTKZ on page 99;
