BlueNRG-LP for indoor positioning

BlueNRG family, Bluetooth Low Energy system-on-chip, BlueNRG-LP, BlueNRG-LPS

The ST BlueNRG, Bluetooth® Low Energy device family includes extensive support in the form of evaluation boards, software development kits, application notes, and design guidelines. These resources help developers implement Bluetooth wireless connectivity in a wide variety of applications, including indoor location solutions.

Asset tracking, ID location, and item finding are just some of the applications that Bluetooth technology and BlueNRG hardware and software tools support and enable.

STSW-QUUPPA-ETAG evaluation software for indoor tracking applications

The STSW-QUUPPA-ETAG evaluation software package is available for the BlueNRG-LP and BlueNRG-LPS Bluetooth® Low Energy SoC. It enables simple prototyping and evaluation of a real-time location system application based on proprietary Quuppa technology and related gateway infrastructure.
The software allows the BlueNRG-LP/BlueNRG-LPS to operate as a Quuppa finder tag according to the Quuppa tag emulation and back-channel specification.

The package includes the ST Quuppa tag emulation library and software application code to build fully sensored device tags quickly. It also features location-tracking capability, multiple sensor data provisioning, and a framework for custom back-channel commands used through the Quuppa positioning system.

Quuppa is a leading provider of real-time locating systems (RTLS): its indoor tracking solution is reliable, versatile, customizable, scalable, and cost-effective.

Indoor Positioning enabled by Bluetooth Direction Finding features

The Bluetooth 5.1 Core Specification introduces Direction Finding features to enhance the performance of Bluetooth location service solutions. These features allow devices to determine the direction of a Bluetooth signal, enabling the development of powerful, low-cost, and real-time locating systems, indoor positioning systems, item finding solutions, asset tracking, point of interest (PoI), and more, improving location accuracy down to tens of centimeters.

The Bluetooth Direction Finding features support two methods for determining the direction of Bluetooth signals using an antenna array: angle of arrival (AoA) and angle of departure (AoD).

The BlueNRG-LPS fully supports both AoA and AoD methods through the ability to transmit and receive special direction-finding signals and take IQ samples needed for calculating the relative signal direction.

BlueNRG-LP/LPS device

The 3rd generation BlueNRG-LP and BlueNRG-LPS Bluetooth® Low Energy SoC are Bluetooth 5.2 and 5.3 certified. They combine a state-of-the-art 2.4 GHz Bluetooth® Low Energy radio with a programmable Arm Cortex-M0+, embedded memories, and a set of peripherals. The SoC implements the latest Bluetooth features to increase communication range, raise throughput, strengthen security, and save power.

The ultra-low-power radio is optimized to consume as little as 3.4 mA in receive mode, 4.3 mA when transmitting, and less than 600 nA in standby. Together with its very straightforward and highly efficient architecture, the device is ideal for battery-operated location tags and fully sensored asset tracking devices.

Get started

ST Quuppa tag emulation

Follow these simple steps to configure an STEVAL-IDB011V2 or STEVAL-IDB012V1 kit with BlueNRG-LP or BlueNRG-LPS SoC as an ST Quuppa tag emulation device:

Unzip/extract the en.STSW-QUUPPA-ETAG.zip file under its local STSW-BNRGLP-DK software package installation folder
Open ST Quuppa tag emulation IDE project (IAR or Keil® or WiSE-Studio) available in the Projects/BLE_Examples/BLE_Quuppa_Tag_with_Lib folder.
Power the STEVAL-IDB011V2 or STEVAL-IDB012V1 through USB (PC USB port) or battery.
Build and download the ST Quuppa tag emulation on the selected platform using the appropriate IDE download option. Alternatively, drag and drop the BLE_Quuppa_Tag_with_Lib.hex onto the STEVAL-IDB011V2 or STEVAL-IDB012V1 found on the Windows navigation tree. You can also use the RF-Flasher utility tool.
If the STEVAL-IDB011V2 or the STEVAL-IDB012V1 is connected to a PC USB port, open a serial communication terminal like HyperTerminal or TeraTerm on your PC to receive debug messages.
Configure the port with the following settings:
  • 115200 baud rate
  • 8 bits data
  • 1 start bit
  • 1 stop bit
  • no parity
  • no hardware flow control

On power-up, the user receives a welcome message on the terminal and several messages regarding device state transitions:

BlueNRG-LP ST Quuppa tag application (version: 1.0.0)
aci_gatt_srv_init() --> SUCCESS
aci_gap_init() --> SUCCESS
STORAGE state: press button or trigger acceleration!

ST Quuppa tag emulation is then ready for use in a Quuppa positioning tracking system.
