/* EXAMPLE_START(a2dp_source_demo): A2DP Source - Stream Audio and Control Volume
|

/* EXAMPLE_START(a2dp_multi_source_demo): A2DP Source - Stream Audio
|
||||
*
|
||||
* @text This A2DP Source example demonstrates how to send an audio data stream
|
||||
* to a remote A2DP Sink device and how to switch between two audio data sources.
|
||||
* In addition, the AVRCP Target is used to answer queries on currently played media,
|
||||
* as well as to handle remote playback control, i.e. play, stop, repeat, etc. If HAVE_BTSTACK_STDIN
|
||||
* is set, press SPACE on the console to show the available AVDTP and AVRCP commands.
|
||||
*
|
||||
* @text To test with a remote device, e.g. a Bluetooth speaker,
|
||||
* set the device_addr_string to the Bluetooth address of your
|
||||
* remote device in the code, and use the UI to connect and start playback.
|
||||
*
|
||||
* @text For more info on BTstack audio, see our blog post
|
||||
* [A2DP Sink and Source on STM32 F4 Discovery Board](http://bluekitchen-gmbh.com/a2dp-sink-and-source-on-stm32-f4-discovery-board/).
|
||||
*
|
||||
* to one or more A2DP Sink devices.
