A2DP
*****
The :code:`a2dp` command exposes parts of the A2DP API.
The following examples assume that you have two devices already connected.
Here is a example connecting two devices:
* Source and Sink sides register a2dp callbacks. using :code:`a2dp register_cb`.
* Source and Sink sides register stream endpoints. using :code:`a2dp register_ep source sbc` and :code:`a2dp register_ep sink sbc`.
* Source establish A2dp connection. It will create the AVDTP Signaling and Media L2CAP channels. using :code:`a2dp connect`.
* Source and Sink side can discover remote device's stream endpoints. using :code:`a2dp discover_peer_eps`
* Source or Sink configure the stream to create the stream after discover remote's endpoints. using :code:`a2dp configure`.
* Source or Sink establish the stream. using :code:`a2dp establish`.
* Source or Sink start the media. using :code:`a2dp start`.
* Source test the media sending. using :code:`a2dp send_media` to send one test packet data.
