Bluetooth 蓝牙守护进程的初始化序列

我正在研究Bluez的轻量级蓝牙工具，它不依赖bluetooth和dbus。BlueZ的文件夹“src/shared”中有此类工具的代码。例如：btgattclient.c在编译时生成“gattclient”。gattclient能够连接到ble外围设备并读取/写入或接收来自ble设备的通知，但它需要初始化hci0接口，Bluetooth正在这样做

在运行bluetooth执行init之后，如果我杀死了bluetooth，gattclient仍然可以很好地连接到一个ble设备并接收通知。Bluetooth似乎正在适配器上执行一些设置或初始化，以使“socket connect（）”成功，而不运行Bluetooth来执行其初始化，gattclient将为“connect（）”套接字调用返回“connection sequenced”。btmon日志显示，“connect（）”在主机本身失败，没有到目标BD地址的连接请求

如果这里的BLE专家能够指出Bluetooth的init序列/命令，这将非常有用，这样我就可以手动（使用btmgmt）或以编程方式实现它，以促进gattclient的成功工作

以下是Bluetooth启动时的btmon日志-
