| Bluetooth: A2DP Shell |
| ##################### |
| |
| 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. |
| * Source or Sink suspend the media. using :code:`a2dp suspend`. |
| * Source or Sink release the media. using :code:`a2dp release`. |
