* *
* @text This A2DP Source example demonstrates how to send an audio data stream * @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. * to one or more A2DP Sink devices.
* 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/).
