1Product Description
1.1 Overview
This document provides a user manual for the BLE Asset Tracker (formerly known as the LoRa IoT
BLE Tracker)developed by TEKTELIC Communications Inc. Henceforth in this document it will be
referred to as the BLE Tracker, or simply, the Tracker.
The Tracker is a BLE-capable LoRaWAN IoT sensor that is powered by a single AA-cell LTC battery
and packed into a compact IP30 enclosure. The Tracker is intended for scanning and reporting
neighboring BLE peripherals (devices) up to a range of approximately 100 m (LoS). The Tracker
can be utilized for a wide variety of asset-locating applications; for example, as a proximity sensor
to provide location information in indoor or outdoor environments. The Tracker is also equipped
with an accelerometer that detects movement to trigger a report. The accelerometer output
vector can also be reported periodically if knowledge of the Tracker orientation is of interest.
Additional sensing functions on the Tracker include on-board temperature and battery voltage.
The battery lifetime of the Tracker has been estimated to be up to 5 years or more, depending
on usage. Table 1-1 presents the available Tracker models.
Table 1-1: BLE Asset Tracker Models.
The main features of the Tracker are summarized as follows.
•BLE: Low-Energy Bluetooth scanning and reporting of nearby BLE-equipped devices to
function as a proximity sensor.
•Accelerometer: A high-sensitivity device that can measure any shock or movement
events. Can be used as an on/off switch for the Tracker to report location data only when
motion is detected.
•Thermometer: the temperature is measured from the on-board MCU transducer.
•Push Button: Externally accessible button for triggering ULs and opening a receive
window for DLs.
•Battery Gauge: Fuel gauge for the LTC batteries that can provide accurate results with
ultra-low average power consumption.

1.2.1 Bluetooth Low-Energy Scanner
The Tracker is equipped with a BLE module that is embedded in the MCU. It serves as a BLE central
device that periodically searches to discover nearby BLE peripherals. It can be used as a
standalone proximity sensor that can also help at positioning.
The BLE scan can be disabled entirely or enabled at any time. Figure 1-3 shows the BLE scan
scheme when the BLE scan is enabled. As shown in the figure, BLE scans are performed
periodically. Each scan duration is divided into scan intervals. The BLE scan is performed only in
the scan window portion of the scan interval. The ratio of the scan window to the scan interval
shows the scan duty cycle. In the case of the scan window equalling the scan interval, the scan
duty cycle is 100%. This represents a continuous scan over each scan duration. This will increase
the likelihood of finding more beacons, but at the expense of consuming more power. The scan
period, duration, interval, and window are all configurable (see the TRM document for
configuration details [1]).
Figure 1-3: The BLE Scan Schematic Procedure.
At the end of each scan duration, up to n discovered BLE devices with the strongest RSSIs are
reported over LoRaWAN. The value n is user configurable (see TRM) [1]. If no devices are found,
an empty list is uplinked. Over each scan duration, a BLE device beacon may be observed
(discovered) more than once, in which case the RSSI associated with the BLE device at the end of
the scan duration is the average value over all observed RSSIs.
The Tracker supports BLE of Bluetooth 5.0. The BLE scan is performed in the passive mode only,
i.e. the Tracker listens to surrounding beacons, but does not transmit to them to request
additional information.
NOTE: The BLE scan is exclusive to LoRa radio transmission; i.e. they do not overlap. If any
reporting becomes due at the same time of a BLE scan, the reporting will be done after the BLE
scan is complete.
