Overview of this book

C++ is a great choice for embedded development, most notably, because it does not add any bloat, extends maintainability, and offers many advantages over different programming languages. Hands-On Embedded Programming with C++17 will show you how C++ can be used to build robust and concurrent systems that leverage the available hardware resources. Starting with a primer on embedded programming and the latest features of C++17, the book takes you through various facets of good programming. You’ll learn how to use the concurrency, memory management, and functional programming features of C++ to build embedded systems. You will understand how to integrate your systems with external peripherals and efficient ways of working with drivers. This book will also guide you in testing and optimizing code for better performance and implementing useful design patterns. As an additional benefit, you will see how to work with Qt, the popular GUI library used for building embedded systems. By the end of the book, you will have gained the confidence to use C++ for embedded programming.

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...
