Configuring EYE beacons

From Teltonika Telematics Wiki

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 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. 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

*iOS doesn't show devices with iBeacon protocol

Configuring device

Before Beacon configuration, visit how to set up your device for the very first data sending to the server: Setting up your configuration for the very first data sending to the server

These are instructions on how to easily configure EYE beacon with Teltonika Configurator on GH5200 device.

1. First the device Bluetooth® settings need to be configured. These are the required steps:

  • Press Bluetooth® settings
  • Turn on BT Radio by pressing Enable (hidden) or Enable (visible)


2. Press Beacon list tab.

  • Select All or Configured (for seeing only preferred beacons) in Beacon Detection options.
  • If you have selected Configured to see preferred beacons, you must add beacons to the Beacons list.
  • Select Periodic option
  • Set Periodic settings according to your needs.
  • After all these steps press Save to device to save the configuration.

To find out how to add beacons to the Beacons list, click on one of the devices: TST100 | TFT100 | GH5200 | TMT250



3. Now you can see detected Beacons in Status -> Beacons List


4. Example of the server view:


In the server view picture above, displayed:

  • The date when the packet arrived to the server
  • Device IMEI number
  • AVL ID 385 – Beacon AVL ID
  • Beacon ID and RSSI

Beacon 1 ID: 0102030405060708090A0B0C0D0E0F00020B010A
Beacon 1 Major: 020B
Beacon 1 Minor: 010A
RSSI: -60

Beacon 2 ID: AAAAAAAAAAAAAAAAAABBCC526F6F6D31

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.

Device Name has the following default value for Beacon – ID1_XXXXXXX

Flag Encoded Data

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

7 - Battery voltage value presence 1 Battery Voltage


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

Packet parsing example

Beacon AVL ID:385 has the following structure:

AVL ID 385 Parsing
Data part BLE beacon flags #1 Beacon ID #1 Signal Strength #1 Beacon data #2
1 Byte 1 Byte 20/16 Bytes 1 Byte …
First half byte – current data part

Second half byte – total number of data parts

Bitwise parameter, specify BLE beacon type and parameters.

Two options available are:

21 iBeacon with RSSI

01 Eddystone with RSSI

Beacon – 20B (UUDI, major, minor)

Eddystone – 16B (Namespace, Instance ID)

Signed 2's complement
