/****************************************************************************
* The demo shows BLE and classic Bluetooth coexistence. You can use BLE GATT server and classic bluetooth A2DP together.
* The BLE GATT server part of the demo creates a GATT service and then starts advertising, waiting to be connected by a GATT client.
* After the program is started, a GATT client can discover the device named "ESP_COEX_BLE_DEMO". Once the connection is established,
* GATT client can read or write data to the device. It can also receive notification or indication data.
* Attention: If you test the demo with iPhone, BLE GATT server adv name will change to "ESP_COEX_A2DP_DEMO" after you connect it.
* The classic bluetooth A2DP part of the demo implements Advanced Audio Distribution Profile to receive an audio stream.
* After the program is started, other bluetooth devices such as smart phones can discover the device named "ESP_COEX_A2DP_DEMO".
* Once the connection is established, audio data can be transmitted. This will be visible in the application log including a count
2018-01-27 04:18:21 -05:00
* of audio data packets.

component/bt: implement AVRCP Target APIs 1. Add more notification events to the enum according to the event list in AVRCP specification. 2. Add API and callback events for basic AVRCP target functionalities to do init, deinit, callback-registration, connection status indication. 3. Implement API to set/get supported PASSTHROUGH command on local AVRCP TG, implement callback events for remote passthrough command indication. 4. Implement API to set/get supported notification eventIDs on local AVRCP TG, implement API to send event notifications to remote CT. \ Currently supported event in TG only includes ESP_AVRC_RN_VOLUME_CHANGE(0xd), which can be extended in later commits. 5. Implement callback events for SetAbsoluteVolume command indication on TG. 6. Add limitation of event_ids supported in RegisterNotification command in CT. The supported event_ids include: \ ESP_AVRC_RN_PLAY_STATUS_CHANGE(0x1), ESP_AVRC_RN_TRACK_CHANGE(0x2), ESP_AVRC_RN_PLAY_POS_CHANGE(0x5), ESP_AVRC_RN_VOLUME_CHANGE(0xd). 7. Add feature bit mask in parameter of callback event ESP_AVRC_CT_REMOTE_FEATURES_EVT for peer feature information got from SDP. 8.
