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 3 second intervals.
• Eddystone 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 Shortlist.jpg or in default list. When looking at devices in default list you will be able to open Detailed view Detailed.jpg of devices and check transmitted data statuses. Additionaly if you are looking for specific devices you will be able to use Search Search button eye app.jpg 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. If you select to Configure device new window will open with Basic and Advanced settings.

Configure window: In this window you can check and change device configuration settings. In main tab Basic Settings you can change main settings. Change Device name, Power signal strength, Advertising interval and Packet transmition type*. For more settings go to Advanced settings tab to enable various events.

Advanced configuration window: Beacon information (iBeacon ID*, Eddystone ID). UUID/MINOR/MAJOR parameter can be changed for iBeacon ID*. Namespace ID/Instance ID can be changed for Eddystone ID

FM Tracker Configuration

Teltonika configurator (standard functionality)

If you have firmware / configurator which does not support EYE Beacon tab in Bluetooth 4.0 section, then you can use Beacon list section of the configurator to scan available EYE Beacons.
Below are short instructions which show how we recommend configuring the device to Enable the Beacon functionality for testing.

Steps to follow according to the visual representation

  1. In System Settings Enable Codec8 Extended;
  2. In Bluetooth settings Enable Bluetooth, set this setting as either "Enable (hidden)" or "Enable (visible)", otherwise Bluetooth will be disabled;
  3. In Bluetooth 4.0 settings, 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;
  4. In Beacon list settings, configure Beacon Detection as "All" and Beacon Record as "Eventual". This will detect all surrounding Beacons and create Beacon records every 30 seconds.

Teltonika configurator new functionalities (not released yet)

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.
  • Beacon - Parameters to enable Beacon scanning scenarios.

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.

Beacon detection - Parameter controls over all Beacons scanning:

Beacon detection configurator.png
  • Disabled – Beacon scanning and transmitting disabled.
  • All – Read all visible beacons;
  • Configured – Read only beacons set in Beacon List;
  • Teltonika MAC – Filter and transmit only Teltonika EYE packets*.
    *It allows to filter only MAC addresses which will be assigned to BTSX device. The MAC address that is currently filtered by this parameter is 7C:D9:F4:0X:XX:XX. 

Beacon record

Beacon record on change.png

Eventual settings have two modes:

  • Monitoring - Beacon record generating every scan period
  • On change - Beacon records are generated only when there are changes in scanned list.

Periodic - records are generated according to Period settings. When there is no visible beacons, empty record will be generated.

Beacon Mode

Beacon Mode SImple.png
  • Simple - beacon parsing is done automatically (Eddystone and iBeacon protocols are supported).
  • Advanced - beacon data capturing can be configured.

Filter type

Filter Type.png

New firmware has two Beacon lists, so it is possible to create two separate lists of beacons, standard one with Beacons ID (UUID:Major:Minor, or Namespace:InstanceID) and new one according Beacon Name (by name or prefix, for example all beacons with prefix "ID1" can be saved.

  • Beacon ID - configurator allows to configure beacon id in iBeacon or Eddystone format.
  • Beacon Name - user can enter names of beacons which needs to be filtered. It would filter the full name or only if the prefix of the name is configured like “BTS”.

Both ID and Name filters can work at the same time. If beacon doesn’t match ID filter, but matches the name, it will be added to beacon list. Filtering only works Beacon Mode is set to Simple.



Proximity Events allow to configure 3 different zones: Near, Away, Far Away. There is additional Lost parameter for beacons which were lost from any of the 3 zones. Averaging timeout determines period how often results are evaluated to avoid fake event detection. Periodic option will generate records at known interval while On Change option will generate record when beacon enters/exits certain zone.

Proximity IO elements have the following structure 1st beacon protocol version.png

EYE Beacon Protocol overview

Beacon advertising

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).

Device Name has the following default value for Beacon – ID1_XXXXXXX

Table 1. Flag Encoded Date
Data Size (Bytes) Description
Flags 1 Each set bit (0-7) means the presence of value (0-7). Bits:

0 – Temperature value presence
1 – Humidity value presence
2 – Magnetic sensor presence
3 – Magnetic sensor state (1 magnetic field is detected/0 magnetic field is not detected) Valid value is present only if bit 2 flag is set.
4 – Movement sensor counter
5 – Movement sensor angle
6 – Low Battery indication (if set to 1 low battery voltage detected)
7 – Battery voltage value presence

Note: only bolded bits (6 and 7) can have value 1, on BTSID1

Value 7 1 Battery Voltage

Battery voltage in mV = 2000 + VALUE * 10
NOTE: present only if bit 7 is set, otherwise is not being sent
