Abstract
In recent years cars are becoming more and more connected, it has become commonplace to connect one’s phone to the car interface, allowing streaming of music, navigating, making calls and sending messages. The primary technology used for connection is Bluetooth, a short-ranged wireless communication technology that has been around since 1999 and improved and expanded upon ever since. It is of vital importance to evaluate the performance of Bluetooth in an in-car system to assess the effect of software updates and other changes. In this thesis we investigate ways to develop a test for Bluetooth performance in a car environment from a customer’s perspective. Connection times of relevant Bluetooth profiles and phone book along with a total time are measured to simulate a scenario of a person entering their car and automatically connecting a phone to the car infotainment unit. The software of the test is developed in the source code of the infotainment unit to allow for evaluation in a lab as well as in a cars. The test is run repeatedly in a lab to produce 10000 measurements for two different phone models. The results show consistency in a lab environment and potential for implementation in the real world with further improvements. The results from the test can be used to evaluate differences in connection times for various car and phone models, or to continuously monitor the connection performance in a single setup.
