FAQ

How can I extend the range of the BT510 Sensor?

The Sentrius™ BT510 sensors range is dependent on a number of factors some of which are under user control.
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.
This includes being able to configure

  • Tx power
  • LE Coded (Long Range) PHY

More details are available via the BT510 user guide.

It is also possible to extend the range of the BT510 using the Laird BL654 Repeater/gateway smartbasic programs this allows the Laird BL654 module to function as a repeater or gateway for adverts from Laird’s BT510 sensors. It can also operate in AT mode where it can advertise, scan, connect, and offer GATT client and server capabilities. This application is controlled with the industry standard AT command protocol over a UART interface.

  • BT510 Repeater Mode–The module listens for adverts from Laird’s BT510 sensors or other BT510 repeaters and rebroadcasts over the air so that a range extension can be facilitated. All other adverts are ignored.
  • BT10 Gateway Mode–The module listens for adverts from Laird’s BT510 orBT510 Repeaters and sends them out in hex format over the UART interface so that a host can process them. It could forward to the cloud if it has the appropriate connectivity. All other adverts are ignored.
  • Generic BLE Client/Server Mode–The module can be made to advertise, scan, connect, and pair. In addition, it can enable the creation of a GATT server table on-the-fly and, conversely can be a GATT client to interact with remote GATT servers.

More details are available via the BT510 Repeater/Gateway user guide.
The source code for all of these applications is hosted on our GitHub page:

Is the BT510 sensor battery replaceable?

Yes, the BT510 Sentrius™ BT510 sensor is replaceable by removing the rear battery door cover.

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

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

Can I access the accelerometer data in the BT510 sensor?

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.

Access to accelerometer values is not possible but it is possible to configure the accelerometer sensitivity. 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. The BT510 accelerometer creates a movement event.
More details can be found in the BT510 user guide.

How long will the BT510 sensor battery last?

The Sentrius™ BT510 is a Bluetooth 5 Low Energy multi-sensor and can last for months or years on its replaceable coin-cell battery. That battery life is dependent on lots of factors such as sleep time, ambient temperature, and more.

To estimate how long your BT510 application can go on a single battery, adjust the values at the BT510 battery life estimator

Can the BT510 sensor use BLE LE Coded Phy (Long range)?

Yes!

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.

This includes being able to change the PHY to LE coded for long range applications.
The Laird BT510 smartphone applications allows a user to select LE Coded PHY.
LE Coded PHY can also be selected from your own smartphone application using JSON over VSP BLE connections.
Details can be found in the BT510 user guide

Is there a programming cable available for the BT510 Sensor?

The BT510 sensor is configured using a smartphone via BLE out of the box. It is also possible for a developer to load their own C code onto the BT510 via a programming cable.

The BT510 board does not have an on-board J-Link debug IC as some nRF5x development boards, however, instructions from the Nordic nRF5x Segger J-Link; page also apply to this board, with the additional step of connecting an external debugger.

Laird Connectivity will provide the USB-SWD programming board that supports this connector layout, refer to the USB SWD Programmer product page

Can I program the BT510 myself?

Out of the box the BT510 is configured via a smartphone app but this does not allow a developer to reprogram the BT510. However the BT510 can be programmed by a developer using Zephyr in C. More details can be found at the following link.

The Zephyr OS is based on a small-footprint kernel designed for use on resource-constrained and embedded systems: from simple embedded environmental sensors and LED wearables to sophisticated embedded controllers, smart watches, and IoT wireless applications.
