Bidirectional Communication for Bluetooth Low Energy without establishing a connection

Abstract

This paper discusses different concepts and ideas for implementing a bidirectional communication for Bluetooth low energy devices without establishing a connection. Some of these possibilities were tested on their feasibility in an experimental set-up. Other ideas exist only theoretically and are associated with high energy consumption or slow transmission rates. Nevertheless, there is a desire for a simple bidirectional communication using the advertising mode for certain applications.Diese Arbeit beschreibt mehrere Möglichkeiten für eine verbindungslose bidirektionale Datenkommunikation mit Bluetooth low energy (BLE) im Advertising Mode. Einige dieser Konzepte wurden bereits in Versuchen nachgewiesen und auf ihre Machbarkeit geprüft.This paper discusses different concepts and ideas for implementing a bidirectional communication for Bluetooth low energy devices without establishing a connection.
