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

Protocol overwiev
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.
Device Name has the following default value for Beacon – ID1_XXXXXXX
| Data | Size (Bytes) | Description |

| Flags | B7 | Raw value example 0xB7. Data has to be interpretated as binary value.
In this example would be (MSB)11011 0111(LSB) and is parsed from least significant byte(LSB).
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. 000 1100 1100 1011 – 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.
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 | |
