蓝牙Hands-Free Profile功能（HFP）

HFP定义了音频网关设备如何连接到免提设备以实现远程控制和音频连接等功能。
要执行HFP客户端或音频网关功能，您必须首先完成以下过程中的步骤。

设置设备以实现 HFP 功能

先决条件

启用SSH访问您的主机设备。
将DUT和远程设备放在蓝牙附近。

步骤

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10.92.160.222，运行以下命令：

ssh root@10.92.160.222

2、通过输入以下密码连接到 SSH

oelinux123

3、根据需要为HFP客户端或音频网关功能配置DUT

为HFP客户端功能配置DUT

为HFP功能设置初始设备后，对HFP客户端执行以下操作：

通过在 SSH 中运行以下命令来验证 ofono 服务的状态：

systemctl status ofono

在文本编辑器的 /etc/pulse/目录中打开脉冲配置文件system.pa。
将headset=ofono添加到文件中的以下行：

Load module bluetooth discover
load-module module-bluetooth-discover headset=ofono

该文件必须如下所示：

### Load module bluetooth discover
load-module module-bluetooth-discover headset=ofono

### Load module bluetooth policy
load-module module-bluetooth-policy
sh-5.1#

保存文件。
通过运行以下命令重新加载守护进程：

systemctl daemon-reload

通过运行以下命令重启 PulseAudio：

systemctl restart pulseaudio

重新加载守护程序并重新启动PulseAudio后，system.pa配置文件中的更改会反映在系统中。使用DBUS在PulseAudio和ofono之间建立连接。

通过在SSH中运行以下命令来运行bluetoothctl：

bluetoothctl

通过从bluetoothctl菜单运行以下命令来验证是否列出了免提客户端设备的UUID：

bluetoothctl

示例输出：

注意：免提音频网关和耳机的 UUID 未列出。仅列出了从 PulseAudio 配置的免提客户端 UUID。

通过在SSH中运行以下命令打开ofono/test菜单：

ls -rt /usr/lib/ofono/test

注意：ofono/test应用程序仅在qcom-multimedia-test-image中可用。要在用户构建中运行ofono/test应用程序，您必须编译它。

示例输出：
