This document provides a comprehensive guide on how to configure the Sentrius™ BT710 Tracker functionality, including Bluetooth parameters, alert parameters, and general use for proximity sensing applications. The Sentrius™ BT710 Tracker or “tag” is a battery powered, Bluetooth v5 integrated sensing and proximity tracking platform enabling tag-to-tag proximity sensing and logging along with tag-togateway communication for log upload.
The Sentrius™ BT710 is shipped with the battery installed and operating in a low power state called Shipment Mode. When it arrives from the factory, the tracker is in shipment mode. To wake the device, press the pushbutton for five seconds until the alarm LEDs turn on and a speaker tone is emitted (startup sequence). This puts the tracker into Active mode. The tracker blinks the status LED yellow waiting for its internal clock to be set, either by the BT710 mobile app or a nearby gateway.
Figure 3 – BLE operations in Active mode When in Active mode, the tracker sequences through a series of BLE operations continuously including Scan, Advertise, and Connected. The Scan Interval parameter determines how much time passes between scan events, at which point the tracker awakes from sleep and performs a BLE scan (discovery of other trackers) for a number of seconds defined by the Scan Duration parameter.
Several indicator styles are available providing control over how alarm LEDs, audible tones, and vibration motor feedback are activated when an alarm is triggered. These styles are configurable using the Alarms tab of the BT710 mobile application. Indicator styles may be selected independently for Alarm 1 and Alarm 2 conditions. The following table (Table 3) describes the styles available for each alarm indicator.
The Sentrius™ BT710 advertises an identifying beacon used by other nearby BT710 compatible Bluetooth tracking devices and gateways to log proximity to the tracker. This advertisement includes information such as a user configurable device identifier, a hardware identifier, and current status of the Bluetooth tracking device. You can configure a tracker using a Bluetooth connection and the Laird Connectivity ‘Sentrius™ BT710 – Bluetooth Tracker mobile application.

The tracker implements two programmable alarms that can be used to trigger local audio, visual, and haptic indicators when a remote tracker is detected for a configured amount of time. Each alarm has a parameter indicating the number of seconds a remote tracker must be detected before triggering the alarm indicators. Each scan interval, the tracker determines which trackers are within proximity and meet the configured RSSI threshold to begin recording.
The BT710 tracker is designed to log data from other compatible tracker devices it observes during its BLE scan operations. The following diagram (Figure 5) shows the data logging timeline and how various parameters affect each logging phase.
The Sentrius™ BT710 mobile application allows a user to configure tracker parameters and update firmware. To use the Sentrius™ BT710 mobile application, follow these steps: 1. 2. 3. From the applicable app store (Apple or Android) search for and install the Sentrius™ BT710 mobile application on your mobile device. To connect to the BT710 tracker, make sure it is in Active mode. Tap FIND BT7 DEVICE to discover the tracker(s) within range of the mobile device. Figure 7 - Scan for BT710 trackers 4.
