1 Introduction

The LTE
CAT1 cellular 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. The LTE

a user or a server application as an endpoint device. It can be queried, updated and configured

either through a serial connection, an over the air IP connection, or through SMS messaging.

The LTE

attached functional elements. These elements include:

Access to these elements and general purpose interfaces is done through an extended AT

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.

The LTE

provides support for specialized hardware features through extended AT

commands. The features supported include the following:

GPS

GPS location functionality is provided by the device GPS receiver. NMEA GPS records can be

extracted in real time from the unit via the UART connection using special debug commands

that are outside the scope of this document.

GPIO

One dedicated input, two dedicated outputs, and one general purpose IO are presented to the

external

are 16V tolerant. These pins default to input and are pulled down representing 0 when

disconnected. They should be asserted to a known value if used.

environment

on the main connector. They are capable of providing system interrupts to

LED’s

Two LED status indicators are provided to verify correct installation and operation. The status

LEDs are color coded and directly convey the status of the cellular and GPS subsystems as

described in the table below. Their valid operation also indicates operational status and power.

Connection

The LTE

provides user control allowing the LEDs to be extinguished once installation is

verified. This feature reduces power and further conceals the LTE

parties wishing to defeat its operation.

On: GPS satellites acquired and Locked

Flash Slow: GPS satellite search is in progress
Off: No power or GPS subsystem fault

On: Indicates LTE connection is made

Flash Slow: LTE subsystem initialization in progress

Flash Fast: LTE initialization but no data connection available
Off: No power or LTE subsystem fault

UART

There are two UART’s provided. A debug UART port is provided for AT commands, data

interaction and optionally for application specific control. A second, application UART is

provided to be used as an expansion port for sensors and other peripherals
