- 例程难度：
本例程创建了几个 GATT 服务并启动了 ADV，ADV 名称为 BLUFI_DEVICE，然后等待连接，可以将设备配置为连接 Wi-Fi 和 BluFi 服务。当 Wi-Fi 连接时，例程将演示如何创建 HTTP STREAM 模块，它可以播放带有 HTTP URI 的音乐。
本例程的经典蓝牙部分实现了 A2DP SINK 部分。程序启动后，智能手机等蓝牙设备可以发现名为 ESP_ADF_COEX_EXAMPLE 的设备，建立连接后，使用 AVRCP 配置文件控制蓝牙音乐状态。
本例程支持的开发板在 $ADF_PATH/examples/README_CN.md 文档中例程与乐鑫音频开发板的兼容性表格中有标注，表格中标有绿色复选框的开发板均可运行本例程。请记住，如下面的 配置 一节所述，可以在 menuconfig 中选择开发板。
本例程涉及 Wi-Fi、A2DP、HFP、Bluetooth LE 共存，所以使用的是优化共存的 IDF 分支：audio/stack_on_psram_v3.3。
本例程默认选择的开发板是 ESP32-Lyrat V4.3，如果需要在其他的开发板上运行此例程，则需要在 menuconfig 中选择开发板的配置，例如选择 ESP32-Lyrat-Mini V1.1。
menuconfig > Audio HAL > ESP32-Lyrat-Mini V1.1
请先编译版本并烧录到开发板上，然后运行 monitor 工具来查看串口输出 (替换 PORT 为端口名称)：
idf.py -p PORT flash monitor
退出调试界面使用 Ctrl-]。
有关配置和使用 ESP-IDF 生成项目的完整步骤，请参阅 《ESP-IDF 编程指南》。
-
本例同时还可以使用共存的 Bluetooth LE 服务，用户使用手机
EspBluFi应用程序连接名为BLUFI_DEVICE的 Bluetooth LE 设备，配置 SSID 和密码然后连接 Wi-Fi 网络。 -
例程开始运行后，等待用户手机主动去连接设备，A2DP 设备广播名为：
ESP_ADF_COEX_EXAMPLE，打印如下：

- 是否使用默认的
sdkconfig.defaults配置，强烈建议使用默认的 sdkconfig 配置。 - 是否使能了蓝牙的双模配置。
- 是否打开了 PSRAM 的配置，或者开发板模组是否配置了 PSRAM 功能。
