TEMPERATURE TRACKING WITH BLE SENSORS

INTRO

The temperature tracking and monitoring industry has a multi-billion-dollar economic and environmental impact worldwide. It is constantly changing and adapting to growing consumer demands. But to remain competitive and profitable, cold chain logistics fleets have to look for innovative and efficient solutions. Bluetooth® technology, combined with vehicle GPS trackers and sensors, opens up new possibilities for fleet and cargo monitoring.

Solution description

To solve the challenges mentioned above, we use the SPECIAL category GPS tracker FMB140  or other FMB EYE Sensor - the brand-new BLE based Teltonika accessory with smart features and extensive functionality set including ID signal transmission, temperature, humidity, and internal battery level tracking.

How it works - the FMB models is based on the FMB platform and supports wireless Bluetooth® LE connectivity, so it can effectively communicate with Bluetooth® devices such as sensors. To ensure the best results, the tracker should be installed in a cold chain vehicle and configured the usual way in the spot where its Bluetooth® antenna is not covered by bulky metal parts nearby.

The compact and lightweight EYE Sensor has to be attached to temperature-sensitive cargo items to be tracked and monitored - the protective bag, outer corrugated carton, container, barrel, pallet, etc. Vehicle GPS tracker receives readings from each sensor over the air at configurable intervals and sends this data as iBeacon or Eddystone profile to a server for analysis combined with the actual temperature, humidity, and its GNSS location details.

Dedicated software developed by a telematics service provider determines and displays all EYE Sensors (thus, tagged items) locations based on proximity to the vehicle tracker and the parameters they track. Because of that, the cargo of cold chain lorry can be monitored via PC, laptop or smartphone in real-time this way notably improving the efficiency of goods management, logistics operations and preventing losses or thefts. But we are not stopping there…

Topology

What you need for a solution?

• FMx1YX device (FMB130is taken as example) which has the ability to connect EYE SENSOR
• The SIM card in order to get data to your server
• EYE Sensor to get temperature data

Installation

1. Install the tracker and connect to power

2. Install EYE Sensors in the required places

3.Configure the device as described below

Configuration

2. Configuring TEMPERATURE TRACKING WITH BLE SENSORS

Codec settings:

• 113 – Data protocol

Parameter ID – Parameter name GPRS settings:

• 2001 – APN
• 2002 – APN username (if there are no APN username, empty field should be left)
• 2003 – APN password (if there are no APN password, empty field should be left)

Server settings:

• 2004 – Domain
• 2005 – Port
• 2006 – Data sending protocol (0 – TCP, 1 – UDP)

2.1 Configuring BLE Sensors

Step 1: Check EYE App Settings:

1. Make sure that name of the sensor is default length (10 symbols) in EYE App Basic Configuration window
2. Note what Packet settings you have set in EYE App Basic Configuration window

Step 2: Configure FM device using Teltonika configurator:

1. In Bluetooth® settings Enable Bluetooth®, set this setting as either "Enable (hidden)" or "Enable (visible)", otherwise Bluetooth® will be disabled;
2. In Bluetooth® 4.0 settings:
   1. set Non Stop Scan to "Disable", configure "Update Frequency" and "Scan duration" as 30 seconds. These settings will bring the best results for BLE scanning with our device;
   2. In Bluetooth® 4.0 settings Advanced Mode Settings Load EYE Sensor preset according to packet settings in EYE app(if you do not have preset you can download them from below table)

Convert HEX value to BIN value:

Then count 28'th BIT from the back (28'th bit value shows locked/unlocked states)

• 1) 10000000000000000000000000110000000000000000000000000101

If car is locked value is 1 and if car is unlocked value is 0

To test the car unlocking and locking use these GPRS commands

• 1) To unlock all doors use this command: "lvcanopenalldoors"
• 2) To lock all doors use this command: "lvcanclosealldoors"
