Bluetooth Low Energy in an embedded system
(2014) EDA920 20132Department of Computer Science
- Abstract
- All around us there is data that could be gathered and processed. The problem is to gather it. Bluetooth Low Energy is a standard that promises cheap battery driven wireless sensors with low energy consumption capable of operating for months on small batteries. For many use cases such a device seem like a perfect fit.
Bluetooth LE has been around for a few years and is now available in most new smartphones. However, there are few practical examples of it being used outside of the smartphone market. The purpose of this thesis is to evaluate the BLE standard and find a way of utilizing BLE sensors together with Axis cameras. This is done by implementing a prototype system capable of communicating with such a sensor and integrating it into... (More) - All around us there is data that could be gathered and processed.

Bluetooth LE has been around for a few years and is now available in most new smartphones. However, there are few practical examples of it being used outside of the smartphone market. The purpose of this thesis is to evaluate the BLE standard and find a way of utilizing BLE sensors together with Axis cameras. This is done by implementing a prototype system capable of communicating with such a sensor and integrating it into the camera event system.
Finally, an existing BLE sensor is adapted and tuned to be capable of reliably communicating events such as door opened within a range of around 20 meters and acting upon these in a camera. The estimated run time of the sensor on two standard AA batteries is around 430 days. With this as basis, some generic recommendations on how to tune the parameters of BLE devices is discussed.
