The purpose of the project was to measure the power consumption of Bluetooth low energy (BLE). The main goal of the project was to study the possibility of using the BLE with the power generated by various energy harvesters to create Internet of Things (IoT). This paper also contains some theoretical research on various energy harvesting systems.
The project was carried out with nRF51422 Development Kit and nRF-Software Develop-ment Kit version 11 developed by Nordic Semiconductors. The BLE embedded in the devel-opment kit was used to measure the power consumption under different circumstances. The BLE device goes through various phases due to its protocol stack and consumes various amounts of power at each stage. Although the power consumption level is at its peak while the BLE stack is transmitting or receiving, the total power consumption is calculated as the average of various stages.
As a result, power consumption of the BLE was measured under different conditions and life expectancy of the energy source, supplied to run the BLE, was calculated. The calculations were studied to find out the feasibility of the BLE on the IoT.
