The Bluetooth technology is considered commodity these days. BlueZ is deployed in many commercial products, but it hasn't been adopted in the automotive industry yet. In these first efforts to do so, certain domain-specific problems need to be addressed, first of all in terms of API completion and validation. Overall the gap between BlueZ and the UI application needs to be closed.In this presentation we will introduce our approach to solve this and an overview of our ongoing activities in the area of Bluetooth Telephony. Existing Open Source components and APIs will be presented, along with our architectural proposal for the main automotive-specific use-cases. In addition, we will summarize our experience on collaborating with the community and on contributing code to such projects.
