EYE App Configuration

Devices work constantly and are ready to perform out of the box. Default basic Sensor settings are set to:
• Transmitting at 2 dBm power.
• Data advertising at 1 second intervals.
• Eddystone and Sensors protocol

If you would like to change these settings you will need to:
1) Download and install EYE APP - Teltonika application to change sensor settings.

Eye App Overview

With the application you will be able to scan for visible Teltonika EYE devices, check their statuses or connect for configuration or firmware update.

Devices in view

In this window you will see all visible devices. You have options to see devices in Short list or in default list. When looking at devices in default list you will be able to open Detailed view of devices and check transmitted data statuses. Additionaly if you are looking for specific devices you will be able to use Search function to filter search options. When in this window select a device of your choice to connect and after passing pin code (default pin code is 123456) you will go to device overview window.

Overview window

In overview window you can see device details, check firmware version and update if available, go to device configuration settings and download the configuration. If you select to Configure device new window will open with Basic and Advanced settings. Other actions include changing the device PIN code and putting the device to sleep. A device in sleep mode will no longer be findable or connectable via the app. To wake it up, you need to attach a magnet and look for a green LED flashing.

FM Tracker Configuration

Teltonika configurator (Base firmware / advanced mode)

If you have firmware / configurator which does not support EYE sensor tab in Bluetooth® 4.0 section, then you can still use Avanced BLE configuration to connect with EYE Sensors.

To configure FM with BTSMP1 EYE Sensor:

Requirements:

Firmware/configurator version with multiple custom IO fields per sensor, we recommend:

FMBXXX: 03.27.07.Rev.00/1.7.22_B.3.27_R.21 or newer

FMX640: 01.02.03/1.7.24_B.FM64_R.34 or newer (FMB640 does not support for BLE functionality)

Step 1: Check EYE App Settings:

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

Step 2: Configure FM device using Teltonika configurator:

In System settings Enable Codec8 Extended;
In GPRS settings Configure GPRS Settings and Server Settings
In Bluetooth® settings Enable Bluetooth®, set this setting as either "Enable (hidden)" or "Enable (visible)", otherwise Bluetooth® will be disabled;
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)
3. Configure MAC address of the sensor

Teltonika configurator new functionalities (Evaluation firmware / EYE Sensor filtering by name)

Starting with firmware 03.28.04.Rev.207 there is additional tabs available in Bluetooth® 4.0 section that allow for easier configuration to connect FM and EYE sensor or beacon.

It's now possible to connect up to 100 sensors at once just by entering one name in the configurator name list. It's required to enter at least 3 characters(case sensitive) in the name for FM to scan the sensors. Super easy to set up!

For example, the you may order Sensors with special configuration from factory where the EYE Sensor names would be TRAILER_1,TRAILER_2,...,TRAILER_99 and so on.

If you would enter TRAILERS in the EYE Fimrware FM configurator then sensors who meet this name condition, for example TRAILER_1, TRAILER_21 , TRAILER_17, would be scanned, while other sensors named Tools, MP1_123546, etc. will not be scanned. With this option, you can upload one configuration to FOTA web and it doesn’t matter which sensor from the list end user will mount, it will be scanned and sent to the server as long as it meets the name criteria.

Bluetooth® 4.0
Functionalities were reorganized and transferred to Bluetooth® 4.0 configuration tab with additional horizontal tabs selection for specific settings:

Global - Parameters responsible for device scanning ability like power and duratations.
EYE - Parameters to configure data reading from EYE sensors.

Common settings

Non Stop Scan - Enable Non Stop Scan feature, the device will try to scan for the sensors all the time if any of them are configured.
Sensors and Beacons Update frequency - changes sensors temperature/humidity/battery voltage data update frequency. Minimum value: 30s, maximum value: 65535s. Recommended value 30.
BLE Scan Duration - Sensors data reading time. Recommended value 30.
Scan retries until error - Scan retries count, till start to show the value as Error '3000' - sensor disconnected. Recommended value 30.
BT Power Level - Telematics device Bluetooth® power level setting.
BLE Broadcasting service ID - Telematics device can broadcast configured ID.
BLE connection control - Connection mode settings. If broadcasting ID is configured, parameter should be set to Prohibit.

Sensors
Sensor Configuration can be set to Custom Sensors, Eye Sensors or both. With the Custom Sensors setting enabled, any BLE sensor can be configured.
When EYE Sensors is selected, Eye Sensor connectionless functionalities or EYE list search window will appear, depending on the selected EYE Sensor filter.

Name
When EYE Sensors Filter is set to Name, the Eye List search window will appear on the configurator. With this setting, separate EYE Sensor records (AVL ID: 11317) will be generated according to the configured parameters, which are described below:

Data Clear period- defines how long the FM tracker waits when the Eye sensor is not detected before removing it from the Eye Sensor list and not sending the sensor values. If Data Clear Period is set to 0, then the EYE Sensor will not be removed from the EYE Sensor list and it will always be included in the periodic records.

RSSI- Parameter defines the dBm threshold value of when the EYE sensor will be added to the sensor list. If the FM tracker detects the RSSI lower than the configured value, it will not be added to the EYE Sensor list.

Record period - Defines how often the EYE Sensor record (AVL ID: 11317) will be generated when the FM tracker is operating On Stop or On Move modes, according to the configured movement source..

EYE Sensor Settings - Define what sensor readings data is included in to the EYE Sensor Records. Sensor readings which are not needed can be disabled, to reduce data consumption.
EYE Name list - Defines what EYE sensors will be added to EYE Sensor list. For EYE Sensors to be added to the list, only the beginning part of the EYE Sensor local name has to match. For example, if in the EYE name list “EYE_SENSOR” is added and the FM tracker detects EYE_SENSOR1, EYE_SENSOR2, EYE_SENSORXYZ, all these EYE Sensors will be added to EYE Sensor list. If the EYE name list is left empty, all the detected EYE Sensors will be included in the EYE Sensor list. NOTE: If EYE Sensor has a name that matches configured one in EYE Name List and if it has a MAC address, that matches configured one in EYE Sensors filtered by MAC address, then such sensor will not be added to EYE Sensor list, but it’s data will be added according EYE Sensor filtered by MAC IO elements.

Once Eye Sensor filtering by name list is selected, EYE Sensor records containing the AVL ID:11317 will start being generated. Below is an example of how EYE Sensor data is packed into AVL ID 11317
AVL ID 11317 structure

MAC
IF EYE Sensors are selected to be filtered by MAC address, separate EYE sensor records will not be generated; EYE sensor values will be included into regular records with their corresponding IO elements. Up to 4 EYE Sensors can be configured with different MAC Addresses. In the case of filtering by MAC Address, more advanced configuration is possible, as EYE Sensors’ IOs’ Low, High level, Event Only and Operand parameters can also be configured separately for each IO.

Working Mode - parameter has 2 options – Disabled and EYE Sensor. When it is disabled, EYE Sensor IO values will not be included into the records. When EYE Sensor is selected, EYE Sensor IO values will be included into records.
MAC Settings - parameter specifies the MAC address of the EYE Sensor for the FM tracker to read, parse its data and put to corresponding IO elements. If the sensor is not found for set amount of scan retries, error values will be stored into IO elements.
I/O elements - allows for advanced EYE sensor I/O elements configuration.

EYE Sensor Protocol overview

Sensor advertising

Beacon and sensors data

Protocol description

At the highest-level Bluetooth® LE advertising packet consists of Advertising Indication and Scan Response. Both packets can be maximum of 31 bytes in size. Advertising Indication packet is always broadcasted when Scan Response is broadcasted only if Observer device requests it by using Active Scan.

BTSMP1 uses Advertising Indication to send beacon data which can be configured to select between iBeacon and Eddystone protocols or to be disabled at all. In that case, data which is shown as Scan Response in protocol overview will be sent as Advertising Indication without Scan Response following it.

Scan Response is used to send device name and manufacturer specific data. Manufacturer specific data includes Teltonika Company ID (0x089A) and protocol version (0x01). It is followed by Flag Encoded Data (Table 1) and Extended Data (Table 2). Later on, protocol will be highly configurable in and will allow to disable/enable sending of device name or any sensor value allowing to reduce size of the packet being sent.

Teltonika BTSX devices are transmitting one or two packets depending on the selected protocol. Broadcast packet + Scan response packet.

A scan response packet is sent when an active scan is used, within the BLE layer of communication. The default for our FM devices and many other applications for example our EYE Appication or nRF connect Application is an active scan.

There are three protocols, with the following packets:

1.iBeacon + EYE Sensors

2.Eddystone + EYE Sensors

For iBeacon + EYE Sensors and Eddystone + EYE Sensors protocols only iBeacon/Eddystone packet is broadcasted and will be seen by both active and passive scans, to see the EYE Sensors packet you need to use an active scan. In other words in an environment where no BLE devices are scanning with an active scan or in case when there are no scanning devices at all, only the iBeacon/Eddystone packet will be sent by the BTS device to conserve energy.

3. EYE Sensors

With EYE Sensors protocol, the EYE Sensor packet becomes broadcast. In other words, in an environment where no BLE devices are scanning with an active scan or in case when there are no scanning devices at all EYE Sensors packet will be sent by the BTS device.

More Information on Active vs passive scans

Device Name has the following default value for Beacon – ID1_XXXXXXX
