tur*_*urf 33 arch-linux broadcom bluetooth bluez raspberry-pi
我的 raspberry pi 3 B 型运行 Arch,有蓝牙问题。首先:
尽管如此,当我尝试使用蓝牙接口时,它不起作用。
bluetoothctl(作为 root),当我运行“扫描”时,告诉我
Failed to start discovery: org.bluez.Error.NotReady

wminput 找不到蓝牙接口:
No Bluetooth interface found
unable to connect

我在这里不知所措,一切似乎都很好,但没有任何效果。这里发生了什么?

我遇到了同样的问题。结果发现@turf 的答案对我不起作用。
我检查后rfkill
:
$ rfkill list
0: hci0: Bluetooth
Soft blocked: yes
Hard blocked: no
1: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no

我运行了命令:
rfkill unblock all

蓝牙又开始工作了。

就我而言,解决方案是:
bluetoothctl power on
Run Code Online (Sandbox Code Playgroud)
其次是
rfkill unblock all
Run Code Online (Sandbox Code Playgroud)
hci0 被软阻止。
