验证 GAP 功能

要执行蓝牙 GAP 功能，您必须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。
• 将被测设备（DUT）和远程设备置于蓝牙有效范围内。

​

为蓝牙 GAP 功能设置设备

1. 在命令提示符中使用以下命令运行 SSH：
   ssh root@<device_IP_address>
   
   示例 如果设备的 IP 地址为 10.92.160.222，请运行以下命令：
   ssh root@10.92.160.222
   
2. 输入以下密码以连接到 SSH：
   oelinux123
   
3. 运行以下命令打开蓝牙测试应用程序：
   bluetoothctl
   
   示例输出
   sh-5.1# bluetoothctl
   Agent registered        uetoothd...
   [CHG] Controller 22:22:F1:C1:99:C0 Pairable: yes
   
   • 要查看 GAP 功能，请运行以下命令：
     help
     
     此命令提供 bluetoothctl 的主菜单。主菜单包括子菜单和 GAP 功能。要执行 GAP 功能，请参阅 执行蓝牙 GAP 功能。 示例输出
     [bluetooth]# help

执行蓝牙 GAP 功能

您可以使用 bluetoothctl 主菜单中提供的命令执行各种蓝牙 GAP 功能。蓝牙 GAP 功能包括启用和禁用蓝牙、运行和停止查询扫描以发现附近的设备，以及启用设备可发现模式。GAP 还支持与远程蓝牙设备配对、查看已绑定或已配对设备的列表以及取消设备配对。
