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).
