Using the Bluetooth® Direction Finding Tool Suite#

NOTE: This section replaces UG514: Using the Bluetooth® Direction Finding Tool Suite. Further updates to this user guide will be provided here.

A Real Time Locating System (RTLS) consists of many locators that pick up the signals of asset tags to locate them in 3D space. To calculate the positions of the asset tags, one must know each locator’s position, orientation, and configuration (such as antenna array type, switching pattern, and so on). The Silicon Labs’ Real Time Locating (RTL) library also needs some configuration parameters, such as estimation mode, azimuth, elevation constraints, and so on, to provide the best estimation for a given environment. The Bluetooth Direction Finding Tool Suite is meant to ease development with the Silicon Labs’ RTL library. It provides multiple tools to configure the system, and also helps development with analyzer tools that calculate many output parameters from the observed IQ samples.
