FM Tracker Configuration

Teltonika configurator (Base firmware)

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

In System Settings Enable Codec8 Extended;
In Bluetooth settings Enable Bluetooth, set this setting as either "Enable (hidden)" or "Enable (visible)", otherwise Bluetooth will be disabled;
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;
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 (Evaluation firmware)

Bluetooth 4.0

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 List

Beacons configuration instruction: How to start with FMB devices and Beacons?

Beacon detection - Parameter controls over all Beacons scanning:

Disabled – Beacon scanning and transmitting disabled.
All – Read all visible beacons;
Configured – Read only beacons set in Beacon List;

Beacon Mode

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

Beacon record

On change - Beacon records are generated only when there are changes in scanned list.
Periodic - Beacon record generating according to the configured Record Period on Move and Record Period on Stop parameters.
Beacon Record Priority - When set to None Records will not be generated. Low priority means the Module makes an additional record which will be sent according to configured send period. When High Priority is configured, the Beacon record will be sent immediately to the server as soon as it is generated.

EYE Beacon Settings

The 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 in Beacon List.
Beacon Name - The names of beacons which need to be filtered can be entered. Only the beginning part of the EYE Beacon local name has to match. For example, if in the EYE Beacon name list “EYE_Beacon” is added and the FM tracker detects EYE_Beacon1, EYE_Beacon2, EYE_BeaconXYZ, all these EYE Beacons will be added to EYE Beacon name list.

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. However, Filtering only works Beacon Mode is set to Simple.

Eye feature mode: Proximity

EYE beacon Proximity events is a functionality which creates three different types of records, depending on the captured Beacons RSSI level. This functionality is only supported with Teltonika EYE beacons.
Proximity events consist of near, away and lost events:

When EYE beacon RSSI level is below the first configured threshold, the beacon will be added to Near Beacon Record (AVL ID: 10828)
When EYE BEACON RSSI level is between the second and first configured threshold, beacon is added to Away Beacon record (AVL ID: 10829)
When EYE Beacon RSSI level is lower than the second configured threshold, beacon is added to Lost Beacon record (AVL ID: 10831). In the case of EYE Beacon disappearing from the environment and not being detected by the FM tracker anymore, the beacon will be added to Lost Beacon record and will be removed from Beacon list.

Event modes

Disabled – Record generating is disabled for the selected range
Periodic – Records will be periodically generated for the selected range, according to the configured record period on move or on stop value.
On Change – Records will be generated as soon as the Eye Beacon number changes for the selected range.

Averaging Timeout
This parameter specifies how long it will take current RSSI value to reach new RSSI value. For example, current EYE Beacon RSSI value is -40 dBm. FMB captures same EYE Beacon with RSSI value of -60 dBm. If averaging timeout is configured to be 10 seconds, it will take 10 seconds for RSSI value to reach -60 dBm from -40 dBm. Keep in mind that this is assuming perfect conditions and subsequent EYE Beacon RSSI

Eye feature mode: Lost & Found

Lost & Found EYE Beacon feature.
Purpose of this functionality is to periodically generate records with all EYE Beacon list (AVL ID: 10828) and create eventual On Change records only when EYE Beacon is lost (AVL ID: 10831) or found (AVL ID: 10829).
Lost and Found Beacon records only include EYE Beacon which was lost or found, not the full Beacon list.

If multiple EYE Beacons were found or lost at the same time, multiple will be included into the record.
If Visible Beacon List is enabled, Beacon records containing the list of visible beacons will be generated according to the configured period parameters Record Period on Move and Record Period on Stop

Advanced Beacon protocol is being used to send Lost & Found records.
Note:Same AVL ID’s as for Proximity events are being used, since two features cannot work at the same time.

AVL ID: 10828 Visible Beacon List (periodic)
AVL ID: 10829 Found Beacon List (On Change)
AVL ID: 10831 Lost Eye Beacon List (On Change)

Proximity and Lost & found AVL ID elements have the following structure:

When Proximity or Lost & Found events are sent, the records will always include Beacon RSSI, Beacon ID, low battery indicator and Battery Voltage.

Below is the mentioned Parameters description:

**Table 1. EYE Beacon Parameter IDs**
Parameter ID	Name	Data type	Description
0	Beacon RSSI Level	1 byte unsigned integer	Received signal strength indication (RSSI) value in dBm. Hex value must be converted to decimal from signed 2s complement.
1	Beacon ID	Array	For EYE Beacons that are transmitting using Eddystone protocol: Beacon ID is Namespace , InstanceID (16 bytes) For EYE beacons that are transmitting using iBeacon protocol: Beacon ID is UUID, Major, Minor (20 bytes)
13	EYE Beacon Low battery indicator	1 byte integer	Low battery state measured by EYE beacon; value is either 0 (low voltage not detected) or 1 (low voltage detected)
14	EYE Beacon battery Voltage	2 byte unsigned integer	EYE Beacon battery voltage value in mV

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
