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

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.

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

USB

The USB port is provided for provisioning or debug.

Relay Driver

A 500mA sink capable output pin is provided. This pin is meant to drive a relay coil indented to

interrupt the starter solenoid relay for the ignition circuit to a car.

Power and Battery

The battery monitor is internal analog input scaled such that the DC value of the power input

system is measured. This value is scaled to span the most significant 8 bits

Timers

Timers resident on the baseband chip generate periodic interrupts for power down wakeup,

watchdog support, periodic report generation and other timer related functions.

Watchdog

SQN3223 chipset provides internal software Watchdog. The LTE device also includes an

MCU that acts as a failsafe external watchdog. The MCU power cycles the system, if no

activity is detected for 1 hour.

Accelerometer

The accelerometer can be used for motion detection and driver behavior monitoring.

3.2 Remote Update

The LTE supports OTA field upgrades of the resident application. An over the air

(Trivial File Transfer Protocol) connection is made over a

n IP

connection. A replacement file is

TFTP

then transferred from a server to the LTE and that file replaces the previous application

image. Additionally the whole stack can be updated using an OMA- DM protocol.

3.3 Power Modes

The LTE device supports several power modes that are set by AT commands. In full

power mode the GPS is active and the cellular subsystem will maintain a persistent cellular

connection whenever service is available. IP connection is maintained according to the

configuration of the device.

The device can be put in low power mode whenever it runs on a backup battery or if the external

battery is low or if it is not moving. In low power mode the GPS is not running and the LED’s

are off. The device would return to full power whenever an event occurs that triggers a report.

Those events include:

 Periodic report  GPIO change  IP change  Battery threshold  Heartbeat  Watchdog

11 / 17

 Power-up  Ignition  Trip start and stop

Any hardware or software reset will return the device to full power mode.

3.4 AT Commands

Extended AT commands are specific to the LTE device. They are closely based on

commands that are as similar as possible industry common devices and are essentially subsets of

standard LTE

also available via the serial and USB interfaces.

3.5 Ack’ed Mode

UDP is not a 100% reliable connection and occasional reports or command/responses may be

lost. Since all commands have responses, the server can repeat any command to which there is no

response. In order to assure reliable reception of reports, LTE devices can be confi gured

either in Normal or Ack’ed mode to send the reports. In the Normal mode the reports are simply

sent “as is” with no acknowledgment from the server. In the Ack’ed mode every report sent is

expected to be acknowledged by the server by sending back an ACK message back. If

acknowledgement

not acknowledged after the specified number of attempts, it is queued. If acknowledgement is

received after the report is queued (i.e. past timeout of the last attempt), it is ignored.

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 LTE will attempt

to re-send queued report(s) every time a new report is triggered. If there is more than one report

is not received within the specified timeout, the report is re-sent. If the report is

13 / 17

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’ed mode assures that all reports are received, but adds overhead in time and data. Report

that is not

acknowledged

is sent again and

eventually

will be queued and sent again. The number

and frequency of re-tries is configurable via the Report Acknowledgement command.

3.6 Event Report Format

Reports are encoded as binary hex. It is also echoed to the debug UART in ASCII format.

3.7 Reset

There are a number of resets available on the device. Soft reset only restarts the software

running on the device. Hard reset is caused by resetting the whole basband module via a reset

pin. There is also an option to reset the GPS and the cellular sub-systems individually.

3.7.1 Context Preservation

When a self-initiated reset is performed due to Network Watchdog or by the Reset command

(modes 0, 1), the context of the system is being preserved and is restored after the reset. The

context includes all the periodic timers, the report queue, the odometer, etc. This allows reset

o f the unit as a troubleshooting or preventive measure without losing reports that are already in

the queue or are pending on running timers. Note that the reset process may cause 1-2min of

inaccuracy in the timers and should not be considered as very precise.

3.8 Startup Banner

After a reset a startup banner is printed through the UART only.
