Bluetooth technology has come a long way since its inception in 1994. Originally designed as a wireless alternative to RS-232 cables, it has evolved into a ubiquitous connectivity standard powering everything from headphones and smartwatches to IoT devices and automotive systems. As we look ahead, Bluetooth is poised for even greater advancements, driven by emerging trends in connectivity, energy efficiency, and smart ecosystems.

This example shows you how to calculate the 2-D or 3-D position of a Bluetooth® low energy (LE) node by implementing Bluetooth direction finding features and the triangulation-based location estimation technique by using Bluetooth® Toolbox™. The Bluetooth Core Specification 5.1 [2] introduced angle of arrival (AoA) and angle of departure (AoD) direction finding features to support centimeter-level accuracy in Bluetooth LE location finding.

Using this example, you can:

  • Simulate the direction finding packet exchange between the Bluetooth LE node and each locator to estimate the angles between them.
  • Estimate the location of Bluetooth LE node by using triangulation-based location estimation technique in an additive white Gaussian noise (AWGN) channel.
  • Measure the positioning accuracy of the Bluetooth LE node related to the bit energy-to-noise density ratio (Eb/No).
