最近偶而會發現藍牙無線滑鼠沒有反應,研究出來原因是藍牙裝置沒有啟動。
先安裝bluez-utils套件後,可能會顯示藍牙裝置沒啟動如下。
[linus@arch-nb ~]$ sudo hciconfig
[sudo] password for linus:
hci0: Type: BR/EDR Bus: USB
BD Address: 24:0A:64:AD:5B:84 ACL MTU: 1022:8 SCO MTU: 183:5
DOWN
RX bytes:1094 acl:0 sco:0 events:54 errors:0
TX bytes:768 acl:0 sco:0 commands:54 errors:0
啟動藍牙裝置:
[linus@arch-nb ~]$ sudo hciconfig hci0 up
此時應該就OK了。
