Bluetooth Low Energy (BLE) beacon single and multi-channel scanning delay evaluation for improved home automation user experiences

Abstract

The demand of improving home automation system to control the home appliance in conveniently and efficiently leads to be more concerned about what the user daily activities the way they want to control their home appliances. Since the BLE has the ability to advertise data without the need to be connected to a master (known as BLE beacon). Measuring the best response for best user experience for ESP32 beacon scanner to be used for light control is studied by make the advertisement happen at single and multi-channel and using an ESP32 as scanner with different scanning paraments (ESP32-80 and ESP32-20). The result showed that not only the number of packets on ESP32-80 and ESP32-20 increase, but also it achieve a time response that less than 100ms with 59.47% and 49.93% of received packets for ESP32-80 and ESP32-20 respectively. Advertising on single channel will not only reduce the response time (21% and 14.73% of first packet received on ESP32-80 and ESP32-20 respectively at time that less than 100ms) but also reduce the number of packets received on the ESP32-80 and ESP32-20. It is also shows the ability of using ESP32 as a beacon scanner for home automation system.
