1 Introduction

Bluetooth Low Energy is a personal local network technology that is designed and sold by Bluetooth Special Interest Group (Bluetooth SIG). It is aimed at applications in the fields of medical and health care, sports and fitness, beacon, security, family entertainment and so on. Especially in the fields of industry and building automation, Bluetooth Low Energy has very low energy consumption and extensive wireless networking features, so Bluetooth Low Energy has a vast market. The Bluetooth Low Energy tree structure network is an extended topology based on star structure networks. Using a tree structure allows the network to include more nodes and a wider range, which makes the Bluetooth Low Energy suitable for more wireless control and sensor applications.

TI SimpleLink Bluetooth Low Energy CC26x2 wireless microcontroller as a Bluetooth central or peripheral has the ability to connect to a maximum of 32 other Bluetooth Low Energy devices simultaneously, that also makes it possible to use the TI Bluetooth Low Energy solution to build a larger and extendable Bluetooth Low Energy network. A tree structure network based on SimpleLink CC26x2 wireless MCU is proposed and analyzed in this application report.
