Application Development with Silicon Labs’ RTL Library#

NOTE: This section replaces AN1296: Application Development with Silicon Labs’ RTL Library. Further updates to this application note will be provided here.

This application note provides guidance on how to start developing Bluetooth 5.1 Direction Finding (DF) applications using the Silicon Labs Bluetooth LE stack and the Real Time Locating Library (RTL lib).

Silicon Labs provides sample projects including examples for asset tags and locators to demonstrate Bluetooth LE 5.1-based DF applications. This document provides an overview of the sample projects, software architecture, and a step-by-step guide on how to create your own applications using Simplicity Studio 5 and Bluetooth SDK v3.x.

Using the Bluetooth Direction Finding Tool Suite complements this document with the description of the Simplicity Studio tools that helps development with the RTL library.

Readers of this document should be familiar with the basics and terms of Direction Finding. To learn more about the theory of Direction Finding, see Bluetooth Direction Finding Fundamentals.
