Bluetooth Low Energy Application in home automation

Abstract

Nowadays, the electrical devices for home automation are required to be multifunctional, with high design, and user-friendly. To meet the requirement of simple appearance and various functions, many manufactures create end to end(E2E) solutions e.g. for controlling an air purifier on a mobile device as was done for the commissioner here, remote control of devices with less or even no physical switches.

This trend has excited the release of many communications technologies of Machine to Machine(M2M), like Bluetooth, Zigbee, Zigwave, Enocean.

The author was commissioned by a Finnish air purification company, to develop a local wireless control of a stand-alone purifier device. This device would support cloud message control from the commissioner as application end (later referred to as App). Considering the geographic distance for maintenance, initial Bluetooth setup would help to provide the user access to further manual control or a WIFI configuration.

The thesis project focused on building a Bluetooth communication application on responder side, the purifier itself, to exchange data with the initiator device, the commissioners mobile end, which has App for this. The target here was to present a prototype with full functions, a stable connection and discuss about the further implementation on security pairing.
