Discover our brand-new and certified Bluetooth Low Energy ID sensor model from Teltonika with robust waterproof casing and a long-lifetime battery. The model is designed for a low-cost fast and easy configuration and integration to save precious time, resources, and ensure accountability.

About BTSMP1

Perfect for traceability use cases, delivery tracking, monitoring of various movable objects in logistics (trailers, containers), agriculture (tractor attachments), and constructions (tools and inventory). Sensors data makes it especially suitable for cold chain refrigerator use cases. The built-in accelerometer can detect item movement or fall events. Magnet detection can be used for wireless open/close detection and notifications such as trailer door events, etc. EYE sensor supports iBeacon and Eddystone protocols. The device is fully compatible with the Teltonika firmware platform which provides extended functionality. Configure, scan, and update anytime anywhere with a dedicated Teltonika mobile app

Configurating beacon device

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.
QR.jpg

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 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.

Sensor 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) 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.

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

Value 0 2 Temperature


Value in Celsius * 100
NOTE: present only if bit 0 is set, otherwise is not being sent

Value 1 1 Humidity


Value in percent
NOTE: present only if bit 1 is set, otherwise is not being sent

Value 2 2 Movement Sensor counter


Most significant bit indicates movement state and 15 least significant bits represent count of movement events.
NOTE: present only if bit 4 is set, otherwise is not being sent

Value 3 3 Movement sensor angle


Most significant byte – pitch (-90/+90)
Two least significant bytes – roll (-180/+180)
NOTE: present only if bit 5 is set, otherwise is not being sent

Value 4 1 Battery Voltage


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

Flags B7 Raw value example 0xB7. Data has to be interpretated as binary value. In this example would be (MSB)1011 0111(LSB) and is parsed from least significant byte(LSB).


0 – Temperature value presence. 1 Means device is reading and transmitting temperature value.

1 – Humidity value presence. 1 Means device is reading and transmitting humidity value.

2 – Magnetic sensor presence. 1 Means device is reading and transmitting Magnetic sensor value.

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. 1 Means device is reading and transmitting movement state and count values.

5 – Movement sensor angle. 1 Means device is reading and transmitting angle roll and pitch values.

6 – Low Battery indication. 0 – Means device battery is from 100 to 15 % (When value changes to 1 Battery level is lower than 15 %.

7 – Battery voltage value presence. 1 Means device is reading and transmitting battery voltage value.

Temperature 08B4 Raw value example 0x08B4 hex, 2228 dec.

Raw value needs to be divided by 100.

Real temperature is 22,28 Celsius.

Humidity 12 Raw value example 0x12 hex, 18 dec.

Decimal value is humidity in percent. Humidity 18 %

Movement 0CCB (MSB)0000 1100 1100 1011(LSB) binary

0 - Most significant byte(MSB) represents Movement status. In this case device is not moving 0. If it was 1 device is moving.

000110011001011 – represent detected movements count 3275 decimal value means device has detected total 3275 movement events,

Angle 0BFFC7 C1 – Most significant byte represents device pitch. Device pitch can be from -90 to 90 degrees.

In this example device pitch is 0000 1011 (2's complement) = 11° degrees.


FFC7– Two least significant bytes represent device roll. Device roll can be from -180 to 180 degrees.

In this example device Roll is 1111 1111 1100 0111 (2's complement) = -57° degrees

Battery voltage 6E Battery voltage – raw value example 0x67 hex. Decimal value of parameter 103. To calculate battery voltage need to use calculation 2000 + (VALUE * 10). In this case battery voltage value 2000+(103x10)= 3030 mV
