问题:
scan on时没有扫描到音响、耳机或我的手机,同时我手机也无法扫描到电脑
我想问下,是不是那里没有注意到的细节使得我的蓝牙无法使用?请大家来指点下,谢谢!

很多蓝牙设备默认是不可被发现的状态。比如现代 Android 系统,只有在处于蓝牙配对新设备界面时,它自己才是可被发现的。别的设备通常也会有一个操作用来连接新设备。

可是我已经discoverable on 了,同时手机蓝牙也设置为可发现状态了,也没能相互扫描到,用Ubuntu live启动U盘启动后可以相互扫描到,所以我怀疑我arch在蓝牙设置上是不是有没注意到的地方?

奇怪,我刚试了一下,我这边的情况是:
小米手机:能看到 Sony 手机
Sony:能看到小米手机和电脑
电脑:能看到小米手机和 Sony 手机
实际上小米手机看不到的设备还挺多,大部分大概是信号比较弱吧,但是电脑就在旁边,不知道为什么也看不到。
PS: 小米手机处于随时可被发现的状态……
