帮助在 Ubuntu 20.10 上配置 USB 蓝牙适配器

Question 1

按照官方文档，请发布（的输出參考）

$ lsusb               *** You already did
$ hciconfig
$ hciconfig -a hci0   *** As this appears to be your bluetooth device

另外，还有一些关于该设备问题的帖子供应商 ID/设备 ID数字与您的数字相同（0a12：0001）。

蓝牙适配器配置问题（ID 0a12:0001）。请注意答案，除了需要您尝试一些繁琐的程序外，它们还对您启动和运行加密狗的机会有所帮助。不值得在这里重新发布解决方案，因为它们在 askubuntu 中。

Question 2

诊断

您的输出显示解析问题/etc/bluetooth/main.conf，例如：

bluetoothd[16969]: src/main.c:parse_config() parsing /etc/bluetooth/main.conf
bluetoothd[16969]: src/main.c:parse_config() Key file does not have key “DiscoverableTimeout” in group “General”

bluetoothd[16969]: src/main.c:parse_config() Key file does not have key “PairableTimeout” in group “General”
bluetoothd[16969]: src/main.c:parse_config() Key file does not have key “Privacy” in group “General”

解决方案

/etc/bluetooth/main.conf像这样备份：

sudo mv /etc/bluetooth/main.conf /etc/bluetooth/main.conf.old

然后像这样创建一个新的/etc/bluetooth/main.conf：

sudo nano /etc/bluetooth/main.conf

然后将其复制并粘贴到文件编辑器中：

#NameResolving = true

# Enable runtime persistency of debug link keys. Default is false which

# Restricts all controllers to the specified transport. Default value
# is "dual", i.e. both BR/EDR and LE enabled (when supported by the HW).
# Possible values: "dual", "bredr", "le"
#ControllerMode = dual

# Enables Multi Profile Specification support. This allows to specify if
# system supports only Multiple Profiles Single Device (MPSD) configuration
# or both Multiple Profiles Single Device (MPSD) and Multiple Profiles Multiple
# Devices (MPMD) configurations.
# Possible values: "off", "single", "multiple"
#MultiProfile = off

# Permanently enables the Fast Connectable setting for adapters that

#FastConnectable = false

[Policy]

# The ReconnectUUIDs defines the set of remote services that should try
# to be reconnected to in case of a link loss (link supervision

# empty the reconnection feature gets disabled.
#ReconnectUUIDs=00001112-0000-1000-8000-00805f9b34fb, 0000111f-0000-1000-8000-00805f9b34fb, 0000110a-0000-1000-8000-00805f9b34fb

# ReconnectAttempts define the number of attempts to reconnect after a link
# lost. Setting the value to 0 disables reconnecting feature.
#ReconnectAttempts=7

# ReconnectIntervals define the set of intervals in seconds to use in between
# attempts.
# If the number of attempts defined in ReconnectAttempts is bigger than the
# set of intervals the last interval is repeated until the last attempt.
#ReconnectIntervals=1, 2, 4, 8, 16, 32, 64

# AutoEnable defines option to enable all controllers when they are found.

# in later on. Defaults to 'false'.
AutoEnable=true

然后按Ctrl+x再按保存文件并关闭文件编辑器。yEnter

之后，重新启动系统并测试您的设备。

如果要将设备连接到外部 USB 集线器，请考虑将其直接连接到 PC 上的 USB 端口。

Question 3

确保蓝牙处于活动状态并正在运行。 sudo systemctl status bluetooth.service 我已经使用 Ubuntu 服务一段时间了，可能名称略有不同。

如果它未处于活动状态且未运行，您将需要启用并启动该服务。

sudo systemctl enable bluetooth
sudo systemctl start bluetooth

然后再次尝试 blueoothctl。

编辑：（对您没有影响，但对将来可能读到这篇文章的其他人有影响）如果这是笔记本电脑，请确保没有硬件开关，很多笔记本电脑都有，通常是 Control 或 Alt 之类的东西，也许是 Function 和 F 键之一。有几台笔记本电脑实际上有物理开关，虽然很少，但确实有。
