1 Introduction

The LP-V001 is a self-contained automotive wireless communication device that combines LTE CAT M
cellular connectivity with GPS location. The device is typically installed in a vehicle, either in-dash or
under the hood with minimum distance from the human body not less than 20cm. It is primarily
a location reporting device that responds to requests (user, server) and events (timers, geo­fences). 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 LP-V001 appears to 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
LP-V001 presents itself over these connections as an enhanced cellular modem with attached
functional elements. These elements include:

 GPS location engine
 Accelerometer
 Input/outputs dedicated for ignition, relay, buzzer, and general purpose
 Serial UART port
 Timers
 Watchdog lockup protection
 Power management
 Event reporting
 Voltage monitoring

Access to these elements and general purpose interface 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 LP-V001 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.
