Experiences and Measurements with Bluetooth Low Energy (BLE) Enabled and Smartphone Controlled Embedded Applications
David Tauchmann, Axel Sikora · International Journal of Electronics and Electrical Engineering · 2014
Bluetooth Low Energy extends the Bluetooth standard in version 4.0 for ultra-low energy applications through the extensive usage of low-power sleeping periods, which inherently difficult in frequency hopping technologies. This paper gives an introduction into the specifics of the Bluetooth Low Energy protocol, shows a sample implementation, where an embedded device is controlled by an Android smart phone, and shows the results of timing and current consumption measurements.
