# 通用属性配置文件 Source: [https://docs.qualcomm.com/doc/80-70017-13SC/topic/bluez-gatt.html](https://docs.qualcomm.com/doc/80-70017-13SC/topic/bluez-gatt.html) GATT 是一个服务框架，它使用 ATT 来发现服务，并在对等设备上读取和写入特征值。 要执行低功耗蓝牙 GATT 服务器或客户端功能，必须首先完成以下过程中的步骤。 ## 为低功耗蓝牙 GATT 功能设置设备 **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)。 - 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 用户可以通过 bluetoothctl 的主菜单选项执行一些 GATT 功能，例如连接和扫描。 **示例输出** sh-5.1# bluetoothctl Agent registered uetoothd...
