# 高级音频分发配置文件 Source: [https://docs.qualcomm.com/doc/80-70017-13SC/topic/bluez-a2dp.html](https://docs.qualcomm.com/doc/80-70017-13SC/topic/bluez-a2dp.html) A2DP 定义了如何通过蓝牙连接将多媒体音频从一台设备传输至另一台设备。这种机制也称为蓝牙音频流。 要执行 A2DP 的发送或接收功能，必须首先完成以下过程中的步骤。 ## 设置设备的 A2DP 功能 **前提条件** - 启用 SSH 以访问您的主机设备。相关说明，可参见[使用 SSH 登录](https://docs.qualcomm.com/bundle/publicresource/topics/80-70017-254/how_to.html#use-ssh)。 - 配对 DUT 和远程设备。相关说明，可参见[与远程蓝牙设备配对](https://docs.qualcomm.com/doc/80-70017-13SC/topic/bluez-perform-bluetooth-gap-functions.html#bluez-perform-bluetooth-gap-functions__section_h4c_1bs_lcc_navyanka_08-21-24-1205-46-507)。 - 将 DUT 和远程设备放置在蓝牙附近。 **步骤** 1. 在命令提示符下使用以下命令运行 SSH： ssh root@Copy to clipboard **示例** 如果设备的 IP 地址为 `10.92.160.222`，则运行以下命令： ssh root@10.92.160.222Copy to clipboard 2. 输入以下密码来连接 SSH： oelinux123Copy to clipboard 3. 通过运行以下命令打开蓝牙测试应用程序： bluetoothctlCopy to clipboard **示例输出** sh-5.1# bluetoothctl Agent registered uetoothd... [CHG] Controller 22:22:F1:C1:99:C0 Pairable: yesCopy to clipboard 4. 根据需要转至 Transport submenu 或 Player submenu。 - 请从 `bluetoothctl` 运行以下命令，以便转至 Transport submenu。 menu transportCopy to clipboard **示例输出** [bluetooth]# menu transport Menu transport: Available commands: ------------------- list List available transports show Transport information acquire Acquire Transport release Release Transport send Send contents of a file receive [filename] Get/Set file to receive volume [value] Get/Set transport volume back Return to main menu version Display version quit Quit program exit Quit program help Display help about this program export Print environment variablesCopy to clipboard 要在源中执行 Transport submenu 功能，请参阅[执行蓝牙 A2DP 发送功能](https://docs.qualcomm.com/doc/80-70017-13SC/topic/bluez-perform-bluetooth-a2dp-source-functions.html)。 要在接收端中执行 Transport submenu 功能，请参阅[执行蓝牙 A2DP 接收端功能](https://docs.qualcomm.com/doc/80-70017-13SC/topic/bluez-perform-bluetooth-a2dp-sink-functions.html)。 - 请从 `bluetoothctl` 运行以下命令，以便转至 Player submenu。 menu playerCopy to clipboard **示例输出** [bluetooth]# menu player Menu player: Available commands: ------------------- list List available players show [player] Player information select Select default player play [item] Start playback pause Pause playback stop Stop playback next Jump to next item previous Jump to previous item fast-forward Fast forward playback rewind Rewind playback equalizer Enable/Disable equalizer repeat Set repeat mode shuffle Set shuffle mode scan Set scan mode change-folder Change current folder list-items [start] [end] List items of current folder search Search items containing string queue Add item to playlist queue show-item Show item information back Return to main menu version Display version quit Quit program exit Quit program help Display help about this program export Print environment variablesCopy to clipboard 要在接收端中执行 Player submenu 功能，请参阅[执行蓝牙 A2DP 接收端功能](https://docs.qualcomm.com/doc/80-70017-13SC/topic/bluez-perform-bluetooth-a2dp-sink-functions.html)。 - **[执行蓝牙 A2DP 发送功能](https://docs.qualcomm.com/doc/80-70017-13SC/topic/bluez-perform-bluetooth-a2dp-source-functions.html)** 用户可以使用 `bluetoothctl` 菜单、 `menu transport` 子菜单和 `paplay` 命令执行蓝牙 A2DP 发送功能。 - **[执行蓝牙 A2DP 接收端功能](https://docs.qualcomm.com/doc/80-70017-13SC/topic/bluez-perform-bluetooth-a2dp-sink-functions.html)** 用户可以使用 `bluetoothctl` 菜单、 `menu transport` 子菜单和 `menu player` 子菜单执行蓝牙 A2DP 接收端功能。 **上一级主题：** [验证 BlueZ 堆栈的功能](https://docs.qualcomm.com/doc/80-70017-13SC/topic/verify-bluetooth-functionality-of-bluez-stack.html) Last Published: Jan 23, 2025 [Previous Topic 执行蓝牙 HOGP 功能](https://docs.qualcomm.com/bundle/publicresource/80-70017-13SC/topics/bluez-perform-bluetooth-hogp-functions.md) [Next Topic 执行蓝牙 A2DP 发送功能](https://docs.qualcomm.com/bundle/publicresource/80-70017-13SC/topics/bluez-perform-bluetooth-a2dp-source-functions.md)
