帮助解决我的蓝牙问题

帮助解决我的蓝牙问题

我认为这台机器上的蓝牙可以工作,至少硬件可以。我曾看到它短暂地工作过一次,这意味着它的工作时间可能不止几秒钟。

我遇到了这个问题,但能够解决它: https://askubuntu.com/questions/690863/sound-fluctuates-wildly-back-and-forth-as-sound-device-rapidly-appears-and-disap

我有这个硬件:

sudo bluez-test-adapter list
 [ /org/bluez/599/hci0 ]
    Name = warmachine-0
    Powered = 1
    Devices = dbus.Array([], signature=dbus.Signature('o'), variant_level=1)
    DiscoverableTimeout = 0
    PairableTimeout = 0
    Discoverable = 1
    Address = 24:0A:64:03:BF:94
    Discovering = 0
    Pairable = 1
    Class = 0x000000
    UUIDs = dbus.Array([dbus.String(u'00001000-0000-1000-8000-00805f9b34fb'), dbus.String(u'00001001-0000-1000-8000-00805f9b34fb'), dbus.String(u'0000112d-0000-1000-8000-00805f9b34fb'), dbus.String(u'00001112-0000-1000-8000-00805f9b34fb'), dbus.String(u'0000111f-0000-1000-8000-00805f9b34fb'), dbus.String(u'0000111e-0000-1000-8000-00805f9b34fb'), dbus.String(u'0000110c-0000-1000-8000-00805f9b34fb'), dbus.String(u'0000110e-0000-1000-8000-00805f9b34fb'), dbus.String(u'0000110a-0000-1000-8000-00805f9b34fb'), dbus.String(u'0000110b-0000-1000-8000-00805f9b34fb')], signature=dbus.Signature('s'), variant_level=1)

我这里有几个蓝牙设备,我的手机和耳机,但它们根本无法扫描......然而我看到这台机器注册了蓝牙设备,它们只是没有保持那种状态,之后你根本无法扫描任何东西。

我制作了一个 DKMS 模块,你可以与 3.13 内核一起使用来安装

wget https://www.dropbox.com/s/9yfcg4e2mn1zcs0/fw-0b05-17cf.hcd
sudo cp fw-0b05-17cf.hcd /lib/firmware/fw-0b05_17cf.hcd
sudo apt-get install build-essential dkms linux-headers-$(uname -r)
wget https://www.dropbox.com/s/ol5r9dai967p6by/btusb-dkms_3.1_all.deb
sudo dpkg -i btusb-dkms_3.1_all.deb

重启后蓝牙即可正常运行
