Highly Accurate Power Profiling of Bluetooth Low Energy Communication

Bluetooth technology is widely used nowadays by mobile, embedded and IoT devices. One important aspect that should be addressed by battery powered solutions is energy efficiency, where communication takes an important share or the total power consumption. The main goal of our research is to analyze and profile Bluetooth communication from power consumption and performance perspectives. This analysis is further used to optimize communication on battery powered devices in order to increase the battery lifetime of the application. In our work we managed to identify and measure power consumption and timings of BLE communication at event level with high accuracy.
