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.

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 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 transmission type*. For more settings go to Advanced settings tab to enable various events. In Advanced settings tab you can can configure EYE beacon sensor parameters:

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

Sensor reading interval - how often values are updated by the device

Event advertising settings - how often device will scan for new events

Maximum event duration - how long will one event be advertised

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

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
