Mobilogix VZGAT-CM1-001 GLOBAL ASSET TRACKER User Guide

INTRODUCTION

The GAT is a multi-purpose LTE CAT-M1 / NB1 and 2G (GSM/GPRS/EDGE), IP67 rated mobile asset tracking and monitoring device with various onboard sensors including temperature, pressure, humidity, light, a 3-axis IMU/Gyroscope, and GNSS/GPS. It also boasts WIFI LAAS and BLE (Bluetooth Low-Energy) connectivity. It is designed for applications such as critical asset tracking and cold-chain, with the ability to periodically report sensor data and location data per configurable intervals, and report near-real-time events or alarms, based on configurable intervals and configurable thresholds.

QUICK START

INTERFACES

BATTERY CHARGER USB PORT

The Battery Charger USB Port allows connection of USB power for charging the unit’s internal battery.

BUTTON AND RADIO POWER CONTROL

Pressing the button for 2 seconds toggles radio power. Allow several seconds after button is recognized for the radio to complete its power cycle.
Pressing the button for 10 seconds performs a system reset, after which the radio powers on and performs sensor reporting as necessary.

LED STATUS INDICATORS

POWER LED

The color of the power LED is set according to the percentage battery level remaining as follows:
- Green: Battery level remaining is greater than or equal to 40%.
- Yellow: Battery level remaining is less than 40% and greater than or equal to 20%.
- Red: Battery level remaining is less than 20%.
The power LED stays on when the radio is on and blinks when the radio is off.

RADIO LED

Slow short blinks:Attempting to register on network.
Slow long blinks: Registered and Idle.
Rapid blinks: Data transfer in progress

FIRMWARE

FIRMWARE VERSIONS

BG96: BG96MAR04A04M1G

OPERATING MODES

TEST (MANUFACTURE) MODE

Description:

Used during factory testing, including PCBA test, partial assembly test, etc.
Supports certification activities as well as antenna performance tests (otherwise, a different mode should be defined)

Mode Entry Actions:

Enable all sensors for read/write functionality
Enable UART peripheral for factory test automation
Turn on all modules (where applicable): cellular Wi-Fi, GNSS
Customer production application is disabled

SETUP (SHIP) MODE

Description

How the device leaves the factory and shipped to a warehouse or distribution center
Lowest power state
Mode for long-term storage

Mode Entry Actions:

Disable all sensors and alarms (no data collection)
Turn off all modules: cellular, Wi-Fi, GNSS. Disconnect power supply (if HW-supported) to address quiescent current
Disable beacon/advertising functionality (if applicable)
If device previously deployed, customer has an option to maintain previous device settings/configuration or reset to default values and clear data store.

Mode Exit:

Connect the device to the charger for 10 minutes
Upon exiting Setup mode, the device enters Normal mode

NORMAL MODE

Description

Device operates per customer settings configured in Discovery mode
Starting with the Default profile, Normal mode supports multiple profiles based on situational logic.

Mode Entry Actions:

Device operates per customer default settings, namely the 14-day profile: 15-minute periodic reporting of all onboard sensors.
In Normal Mode, the default GAT profile periodically monitors and provides sensor reports for temperature, humidity, pressure, light, accelerometer, tilt/orientation, battery-level, location, and LTE signal strength (RSRP). A user may disable or decrease the reporting frequency (granularity) of any sensor for which the use case does not apply. Furthermore, alarms can be enabled for near real-time detection and reporting of environmental excursions, motion or tilt alarms.
The GAT supports indoor location using Wi-Fi access points and RSSI trilateration, in addition to location based on enhanced cell ID (eCID), in scenarios where visibility to the sky for GNSS location is compromised or not possible.
The GAT can be configured as a cellular gateway or scanner of remote Bluetooth environmental sensors, such as the Mobilogix BTM250.

HARDWARE

MAIN PROCESSING COMPONENTS

The GAT comprises 2 primary communication and processing modules, the Quectel BG96G, and the Silicon Labs BlueGecko EFR32BG12. The BG96 and EFR32BG12 operate cooperatively and communicate via a dedicated UART serial interface, using a proprietary, message packet-based protocol (Ref. 7, GAT Software Radio to Sensor Message Protocol).

BG96

The BG96 hosts the radio/modem and is primarily responsible for cellular communications to ThingSpace and for GNSS/GPS positioning.

EFR32BG12 (SENSOR PROCESSOR)

The EFR32BG12 is primarily responsible for collecting periodic sensor measurements and for generating events or alarms based on those measurements. It hosts a Bluetooth Low Energy (BLE) radio for use with applications such as reading data such as temperature from a BLE sensor.

SENSORS

GAT has the following peripheral devices that interface to the EFR32BG12 to support system operation and to support taking sensor measurements:

Bosch BMI160 3-Axis IMU/Gyroscope, with up to 16g of motion/force detection, and 0 to 359 degree orientation around 2 independent axes and tilt-angle recognition around 3 independent axes
Bosch BME280 sensor with Temperature (-40 deg C to 80 deg C), Pressure (0 hPa to 1300 hPa), and Humidity (0% to 100%)
Maxim MAX17260 Battery Fuel Gauge
Liteon LTR303 ambient light sensor, with 0 to 64K Lux measurement
Silicon Labs / Expressif ESP8286 WIFI (for LAAS)
1-wire bridge to support a thermistor device
