# 验证 A2DP 功能 A2DP 定义如何通过蓝牙连接将多媒体音频从一个设备传输到另一个设备。这种机制也称为蓝牙音频流。 要执行 A2DP 发送端或接收端功能，必须首先完成以下过程中的步骤。 ## 前提条件 - 启用 SSH 以访问您的主机设备。有关说明，请参阅[使用 SSH 登录](https://docs.qualcomm.com/bundle/publicresource/topics/80-70022-254/how_to.html#use-ssh)。 - 配对 DUT 和远程设备。有关说明，请参阅[与远程蓝牙设备配对](https://docs.qualcomm.com/doc/80-70022-13SC/topic/bluez-perform-bluetooth-gap-functions.html#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。 ## 设置设备的 A2DP 功能 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@10.92.160.222 Copy to clipboard 2. 输入以下密码来连接 SSH： oelinux123 Copy to clipboard 3. 通过运行以下命令打开蓝牙测试应用程序： bluetoothctl Copy to clipboard **示例输出** sh-5.1# bluetoothctl Agent registered uetoothd... [CHG] Controller 22:22:F1:C1:99:C0 Pairable: yes Copy to clipboard 4. 根据需要转到 **Transport 子菜单**或 **Player 子菜单**。 - 要转到 **Transport 子菜单**，请从 `bluetoothctl` 运行以下命令： menu transport Copy 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 variables Copy to clipboard 要在发送端中执行 **Transport 子菜单**功能，请参阅[执行蓝牙 A2DP 发送端功能](https://docs.qualcomm.com/doc/80-70022-13SC/topic/bluez-perform-bluetooth-a2dp-source-functions.html#bluez-perform-bluetooth-a2dp-source-functions)。 要在接收端中执行 **Transport 子菜单**功能，请参阅[执行蓝牙 A2DP 接收端功能](https://docs.qualcomm.com/doc/80-70022-13SC/topic/bluez-perform-bluetooth-a2dp-sink-functions.html#bluez-perform-bluetooth-a2dp-sink-functions)。 - 要进入 **Player 子菜单**，请从 `bluetoothctl` 运行以下命令： menu player Copy 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 variables Copy to clipboard 要在接收端中执行 **Player 子菜单**功能，请参阅[执行蓝牙 A2DP 接收端功能](https://docs.qualcomm.com/doc/80-70022-13SC/topic/bluez-perform-bluetooth-a2dp-sink-functions.html#bluez-perform-bluetooth-a2dp-sink-functions)。 ## 后续步骤 - [执行蓝牙 A2DP 发送端功能](https://docs.qualcomm.com/doc/80-70022-13SC/topic/bluez-perform-bluetooth-a2dp-source-functions.html) 您可以使用 `bluetoothctl` 菜单、`menu transport` 子菜单和 `paplay` 命令执行蓝牙 A2DP 发送端功能。 - [执行蓝牙 A2DP 接收端功能](https://docs.qualcomm.com/doc/80-70022-13SC/topic/bluez-perform-bluetooth-a2dp-sink-functions.html) 您可以使用 `bluetoothctl` 菜单、`menu transport` 子菜单和 `menu player` 子菜单执行蓝牙 A2DP 接收端功能。 Last Published: Nov 03, 2025 [Previous Topic 执行蓝牙 HOGP 功能](https://docs.qualcomm.com/bundle/publicresource/80-70022-13SC/topics/bluez-perform-bluetooth-hogp-functions.md) [Next Topic 执行蓝牙 A2DP 发送端功能](https://docs.qualcomm.com/bundle/publicresource/80-70022-13SC/topics/bluez-perform-bluetooth-a2dp-source-functions.md)
