Application Note 310

Energy optimization of a battery-powered device

Optimizing embedded applications for overall efficiency should be an integral part of the development process as it is important to understand how peripherals, software algorithms, and power saving modes work together.

This application note describes the power consumption analysis of an L-Tek FF1502 Bluetooth Low Energy (BLE) beacon with ULINKplus. Beacons are typically low power devices, which sleep most of the time and wake-up briefly to broadcast a message to nearby portable electronic devices (such as mobile phones for example). We’ll show how to analyze the battery lifetime of an application running on the beacon by using the ULINKplus debug adapter that enables high-precision power analysis together with Arm Keil MDK. The findings are used to improve the hardware design and to implement software changes that lead to reduced power consumption and longer battery life.
