1 Introduction

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.

The device comes pre-configured from the factory. It is ready to use. TheLN-

3.4 AT Commands

Extended AT commands are specific to the LN-L device. 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

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
