Developing Bluetooth Location Services Applications#

Bluetooth Location Services include applications for direction finding (Angle of Arrival and Angle of Departure), High Accuracy Distance Measurement (also called Accurate Bluetooth Ranging), Triangulation, and Trilateration. While Silicon Labs' Real-Time Locating (RTL) library supports all of these, the initial application focus is on providing a Direction Finding Solution for developing direction finding applications using AoA and AoD. These are new technologies that establish a standardized framework for indoor positioning. With these technologies, the fundamental problem of positioning comes down to solving the arrival and departure angles of radio frequency signals.

The content on these pages is intended for those who want to experiment with or are already developing a Bluetooth Direction Finding application using the RTL Library provided with the Bluetooth LE SDK.
