org.bluez.error.inprogress 蓝牙错误

Question

我遇到一个问题，蓝牙连接1-2秒后就断开了，主控端会显示以下错误：

org.bluez.error.inprogress 

追踪日志我看到它会输入以下功能：

并追踪到 blueZ 中的代码：

static DBusMessage *connect_profiles(struct btd_device *dev, uint8_t bdaddr_type,
                    DBusMessage *msg, const char *uuid)
{
    struct bearer_state *state = get_state(dev, bdaddr_type);
    int err;

    DBG("%s %s, client %s", dev->path, uuid ? uuid : "(all)",
                        dbus_message_get_sender(msg));

    if (dev->pending || dev->connect || dev->browse)
        return btd_error_in_progress(msg);  <------------------ HERE
...
}

我的问题是，我能否以某种方式知道哪个条件（待处理/连接/浏览）导致此错误，而无需添加编辑代码，因为我没有权限这样做？如果出现任何这种情况，blueZ 为何会尝试连接到配置文件？

尝试重新启动蓝牙服务。出现了同样的错误，并通过重新启动蓝牙服务设法解决了该问题。

sudo service restart bluetooth

尝试运行上面的命令，看看是否有帮助。
