表示这次买的树莓派3的坑太多了,蓝牙在Arch下都找不到,最终在论坛搜到了一篇帖子

That too, is not yet finished by the people at the Pi Foundation.

原来基金会的人还没有彻底开发完。。。。WTF。。。。

不过好在有国外网友自己根据 Raspbian 下的包,做了个 Arch 下面的。不过是放在了Aur上,
需要用 yaourt 来安装下,这就好办了,这是原贴

注意:是在非root下执行的

$ yaourt -S pi-bluetooth
$ sudo systemctl enable brcm43438.service
$ sudo reboot

重启后,可以看到已经启动成功了,

接下来安装管理工具

1
$ sudo pacman -S bluez bluez-utils

加载mod

1
[root@docker ~]# modprobe btusb

启动设备

1
[root@docker ~]# hciconfig hci0 up

增加配置,可以让设备开机自启动

[root@docker ~]# cat /etc/udev/rules.d/10-local.rules
