如何在 Docker 中使用蓝牙？

Question

我在 Windows/MacOS 上的 Docker 中有一个 Ubuntu 容器。

\n

我想用来bluez与容器中的 BLE 外设进行通信。

\n

service bluetooth start、bluetoothd、 以及hciconfig全部无法扫描通信。

\n

请告诉我是否有任何方法可以做到这一点或了解如何做到这一点。

\n

环境：

\n

Windows 10 Home -> Docker v20.10.14 -> Ubuntu 22.04 LTS (Jammy Jellyfish)\nMacOS Monterey 12.3.1 ->  Docker v20.10.12 -> Ubuntu 22.04.4 LTS\n

\n

我在 Windows/MacOS 上做了什么：

\n

# docker run --name <container> --net=host --privileged -it ubuntu /bin/bash\n

\n

我在容器方面做了什么：

\n

# apt-get update \n# apt-get upgrade -y\n# apt-get install -y dbus bluetooth bluez bluez-firmware\n# service dbus start \n

\n

故障一：bluetooth启动后未激活

\n

# service bluetooth start\n * Starting bluetooth\n# service bluetooth status\n * bluetooth is not running\n

\n

故障二：bluetoothd无法访问接口

\n

故障3：hciconfig无法打开socket

\n

root@docker-desktop:/# hciconfig\nCan\'t open HCI socket.: Address family not supported by protocol\nroot@docker-desktop:/# hcitool scan\nDevice is not available: Address family not supported by protocol\nroot@docker-desktop:/# hcitool dev\nDevices:\n

故障4：无法添加btusb模块

\n

# lsmod\nModule                  Size  Used by\n# modprobe btusb\n\xef\xbc\x88Windows\xef\xbc\x89\nmodprobe: FATAL: Module btusb not found in directory /lib/modules/5.10.16.3-microsoft-standard-WSL2\n\xef\xbc\x88MacOS\xef\xbc\x89\nmodprobe: FATAL: Module btusb not found in directory /lib/modules/5.10.76-linuxkit\n

参考网址：

\n
• bluetoothd 失败并显示：无法访问管理界面：已安装bluez-firmware，但仍然相同
\n
• 蓝牙套接字无法在容器内打开：此站点的btusb结果lsmod，所以我猜情况有所不同
\n
• 从 Docker 内部访问蓝牙适配器？：/sys/class/bluetooth不存在
\n
• 启动时未加载蓝牙模块：无法添加btusb模块
