This document provides a comprehensive guide on how to configure the Sentrius™BT510 Sensor functionality, including

Bluetooth settings and temperature readings, motion, and contact detection.

The Sentrius™BT510 Sensor is a battery powered, Bluetooth v5 long-range integrated sensor

platform enabling robust, reliable sensor data transfer in the harshest of environments. It contains a

temperature sensor, also seamlessly integrating open/close contact and motion/impact detection and

BLE beaconing capabilities. The BT510 is powered by Laird Connectivity’s field proven BL654 BLE

module that integrates Nordic Semiconductor’s nRF52840 SoC silicon.

Note: Laird Connectivity has a comprehensive staff of design services engineers available to help customize the sensor.

Please contact your local Laird sales representative for more details.

See the BT510 product brief for detailed specifications. It’s available from the documentation tab of the BT510 series product

The Sentrius™ BT510 doesn’t have a power switch. It is shipped with an installed battery and is in a low power state called shelf

mode.

To wake the device, firmly press the button in the center of the round face for at least three seconds until the green LED turns

on.

When you release the button, the green LED blinks once a second.

The sensor is in sleep mode from the factory. Pressing the button for three seconds wakes the sensor and it starts to advertise.

The sensor is now ready for normal operation configuration. This can be done using a phone or gateway. The LED blinks for 30

seconds or until a connection is made, the button is pressed again, or the sensor stops advertising. The default state of the

sensor is to advertise indefinitely.

Quickly press the button to perform a battery good check. If the battery is good, the sensor briefly blinks the green LED and

starts to advertise. If the battery is below the recommend operating voltage, then the LED does not blink but the sensor tries to

advertise.

If the button is held for more than ten seconds and released, the sensor performs a factory reset. A factory reset erases all logs,

pairing information, and reset the configuration to its default state.

When the button as shown in Figure 1 is held for 10 seconds, the LED turns yellow or red. If the LED turns red, then factory

reset is not allowed using the button. This is because the sensor is locked. The sensor can be locked by using one of the JSON

properties. When locked, the factory reset can still be performed using Bluetooth. If the LED turns yellowish orange, then factory

reset is allowed. The yellowish orange LED blinks when the button is released.

The battery is a 3-volt lithium of CR2477 type.

Note: The battery door cover has a gasket inside to keep out liquids.

The sensor can be cleaned with a mild, non-abrasive detergent. Because it is not waterproof, do not immerse it in water.

The sensor does not require any calibration.

The Sentrius™ BT510 advertises events. An event can be a temperature measurement, an alarm, a battery measurement, a

button press, a door opening/closing, or movement. The configuration of a sensor determines what kind of events it generates.

You can configure a sensor using a Bluetooth connection and the Laird virtual serial port(vSP) service. The protocol sent over

the virtual serial port is JSON-RPC version 2. This allows you to add new commands and features without changing the

Bluetooth interface. More details can be found at https://www.jsonrpc.org/specification.

Advertising each event once it becomes active is the default behavior of the sensor. This provides ample time for a gateway to

detect an event, maximizes the lifetime of the battery, and allows the sensor to be a good RF citizen. Once a sensor is configured,

it is possible that a gateway never needs to connect to a sensor. If multiple events occur at the same time, the sensor queues

events and advertises each one for the configured advertising duration (default of indefinite).

If the sensor is configured to advertise indefinitely, then the advertisement queue is bypassed.

For each new event, the record number increments. You can use this value to filter out duplicate advertisements.

The TLV (type-length-value) fields are shown in the order that is broadcast by the sensor. However, this order is not guaranteed.

The sensor can be configured to transmit with an output power of +8 dBm. It can also be configured to use the LE coded PHY.

When using the coded PHY, the scan response isn’t used.
