TheLN-Lisaself-containedvehicletrackingdevicethatcombinesGPSlocationwithLTECAT1/3G fallbackcellular connectivity. It is primarily a location reporting device that responds to requests
(user, server) and events (timers, geo-fences). Data reports consist of a single record that contains all location data and system status.

They are closely based on commands that are as similar as possible industry common devices and are essentially subsets of standard LN-L commands. Native AT commands supported by the Quectel EC21-A modules are also available via the serial and USB interfaces. 3.5 Acked Mode UDPisnota100%reliableconnectionandoccasionalreports lost.Sinceallcommandshaveresponses,theservercanrepeatanycommandto noresponse.Inordertoassurereliablereceptionofreports,LN-Ldevicescanbeconfigured eitherinNormalorAckedmodetosendthereports.IntheNormalmodethereportsaresimply sentasis expectedtobeacknowledged acknowledgementisnotreceivedwithinthespecifiedtimeout,thereportisre-sent.Ifthereport isnotacknowledgedafterthespecifiednumberofattempts,itisqueued.Ifacknowledgement isreceivedafterthereportisqueued(i.e.pasttimeoutofthelastattempt),itisignored. withnoacknowledgmentfromtheserver.IntheAckedmodeeveryreportsentis bytheserverbysendingbackanACKmessageback.If orcommand/responsesmaybe whichthereis Report is not considered complete until its acknowledgement is received. Thus, if report X is sent and report X+1 is triggered while waiting for acknowledgement of X, report X+1 will be queued until such acknowledgement is received and only then sent. The LN-L will attempt to re-
send queued report(s) every time a new report is triggered. If there is more than one report queued, the reports will attempt to be sent in the order of triggering and only once the report is acknowledged, the next report is attempted.
