Maya Posch

Maya Posch is a senior C++ developer with more than 15 years of experience. Discovering the joys of programming early on, and later the joys of electronics, she has always expressed a profound interest in technology, a passion that she gladly shares with others. Describing herself as a C developer who happens to like C++ and Ada, she likes to seek the limits of what can be done with the minimum of code and hardware to accomplish everything that is cool, new, and exciting. She also enjoys FPGA development, AI, and robotics research, in addition to creative writing, music, and drawing.

Bluetooth audio sources and sinks

Bluetooth is unfortunately a technology that, despite being ubiquitous, suffers from its proprietary nature. As a result, support for the full range of Bluetooth functionality (in the form of profiles) is lacking. The profile that we are interested in for this project is called Advanced Audio Distribution Profile (A2DP). This is the profile used by everything from Bluetooth headphones to Bluetooth speakers in order to stream audio.

Any device that implements A2DP can stream audio to an A2DP receiver or can themselves act as a receiver (depending on the BT stack implementation). Theoretically, this would allow someone to connect with a smartphone or similar device to our infotainment system and play back music on it, as they would with a standalone Bluetooth speaker.

A receiver in the A2DP profile is an A2DP sink, whereas the other side is the A2DP source. A Bluetooth headphone or speaker device would always be a sink device as they can only consume an audio...
