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. The device comes pre-configured from the factory. It is ready to use. TheLN-Lappearstoauseroraserverapplicationasanendpointdevice.Itcan bequeried,updatedandconfiguredeitherthroughaserialconnection, anovertheairIP connection, orthroughSMSmessaging.TheLN-Lpresentsitselfoverthese connectionsasanenhancedcellularmodemwithattachedfunctionalelements.Theseelements include: • GPSlocationengine • Accelerometer • Input/outputs dedicated for ignition, relay, buzzer, and general purpose • SerialUARTport • Timers • Watchdoglockupprotection • Power management • Event reporting • Voltage monitoring AccesstotheseelementsandgeneralpurposeinterfacesisdonethroughanextendedAT command set. Configuration parameters are stored to flash memory and are automatically used on the next power up event. For more details, please reference the AT Command document. Figure 1

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 Ack’ed Mode UDPisnota100%reliableconnectionandoccasionalreports orcommand/responsesmaybe lost.Sinceallcommandshaveresponses,theservercanrepeatanycommandto whichthereis noresponse.Inordertoassurereliablereceptionofreports,LN-Ldevicescanbeconfigured eitherinNormalorAck’edmodetosendthereports.IntheNormalmodethereportsaresimply sent“asis” withnoacknowledgmentfromtheserver.IntheAck’edmodeeveryreportsentis expectedtobeacknowledged bytheserverbysendingbackanACKmessageback.If acknowledgementisnotreceivedwithinthespecifiedtimeout,thereportisre-sent.Ifthereport isnotacknowledgedafterthespecifiednumberofattempts,itisqueued.Ifacknowledgement isreceivedafterthereportisqueued(i.e.pasttimeoutofthelastattempt),itisignored. 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. This assures that reports are sent and received in order Ack’edmodeassuresthatallreports arereceived,butaddsoverheadintimeanddata.Report thatisnotacknowledgedissentagainandeventuallywillbequeuedandsentagain.Thenumber andfrequencyofre-triesisconfigurableviatheReportAcknowledgement command. 3.6 Event Report Format Reportsareencoded as binaryhex.It is also echoed to the debug UART in ASCII format. 3.7Reset Thereareanumberofresetsavailableonthedevice.Softresetonlyrestartsthesoftware runningonthedevice.Hardresetiscausedbyresettingthewholebasband moduleviaareset
