3.5 Report
TheAPV‐200Ccapturesdataandformsareportrecordwiththatdata.Thisisasingledata
structureintendedtocontainallofthetypicallyusefuldataontheAPV‐200C.Other
informationcanbequeriedseparatelyusingseparateATcommands.
Reportsarealwaysgeneratedbyinterruptsregardlessofwhether
ornotthereisaGPSlock.
Ifnolockhas  everbeenattainedsince hardwarereset, defaultvaluesof0arereturnedfor
allGPSfields.Ifalockhasbeenattainedandlost,thereportwillcontainthe lastvalid GPS
dataincludingthetimestampofthatdata.
BaseRequirements：
1. A report is generated in response to either an interrupt event or in response to
executionofassociatedATcommandsexplicitly requestingone.
2. GPScoordinatesarestoredinreportsassignedhexvaluestosavespace.
3. To reduce data transmission costs, the data within a
report record can be masked
andremovedbeforeitistransmitted.
4. Every report has  a tag and each enabled interrupt or event generates a separate
report.Thereporttagsindicatethecauseofthegeneratedreport,whichcanbean
interrupt,aneventorinresponsetoacommand.
3.6 Reset
Thereisaninternalsoftreset.
3.6.1 Context Preservation
WhenaresetiscausedbytheNetwork WatchdogorbytheResetcommand(modes0,1),
thecontextofthesystemisbeingpreservedandisrestoredafterthereset.Thecontext
includesalltheperiodictimers,thereportqueue,theodometer,etc.Thisallowstoresetthe
unitasa
troubleshootingmeasureeitherperiodicallyorduetoNetworkWatchdogwithout
losingreportsthatarealreadyinthequeueorarependingonrunningtimers.Notethatthe
resetprocessmaycause1‐2minofinaccuracyinthetimersandshouldnotbeconsideredas
veryprecise.
Modes 8/9 of the
IONRS command perform soft and hard reset respectively without
preserving any context. Factory reset (IONFR) also does not preserve any context of the
system.
