蓝牙 USB 加密狗 5.0 0a12:0001 在 Ubuntu 20.04 上不起作用

Question

无线 USB 加密狗 - 蓝牙 USB 加密狗 - MINI 5.0 - 版本 5.48 - 0a12:0001

所以最近我买了一个蓝牙 USB 加密狗 - 型号：MLT-5.0-MiNi

我正在使用 Ubuntu 20.04.1 LTS。

1.将适配器连接到USB端口后，我检查了在终端中输入的端口lsusb，得到以下信息：

Bus 002 Device 003: ID 0a12:0001 Cambridge Silicon Radio, Ltd Bluetooth Dongle (HCI mode)

2. hciconfig -a给出了以下内容：

hci0:   Type: Primary  Bus: USB
        BD Address: 00:1A:7D:DA:71:11  ACL MTU: 679:9  SCO MTU: 48:16

        Link policy: RSWITCH HOLD SNIFF PARK 
        Link mode: SLAVE ACCEPT

3 hcitool dev .：

所以看起来我的电脑没有安装驱动程序。

4. bluetoothctl --version：

bluetoothctl: 5.53

5. rfkill：

ID TYPE      DEVICE      SOFT      HARD
0  bluetooth hci0   unblocked unblocked

6.最后btmon：

Bluetooth monitor ver 5.53
Failed to bind channel: Operation not permitted

---

我找到了这个 YouTube 视频来解决这个问题。

1.首先，我必须安装应用程序“Ubuntu Mainline Kernel Installer”才能更新到最新的内核版本，所以我输入：

sudo add-apt-repository ppa:cappelikan/ppa
sudo apt-get update
sudo apt-get install mainline

2.然后，在更新到最后一个内核版本之前，我必须检查正在运行的内核版本是什么：

User@PC:~$ uname -r

5.4.0-48-generic

User@PC:~$ uname -sr

Linux 5.4.0-48-generic

3.后来我去KERNEL官网查了下最新稳定的Kernel版本是什么，例如：5.8.13

毕竟，我打开了应用程序 Ubuntu Mainline Kernel Installer，然后单击了最后一个稳定的内核版本，例如：5.8.13。最后点击按钮Install。

4.安装重启后，我再次检查：

User@PC:~$ uname -r

5.8.13-050813-generic

User@PC:~$ uname -sr

Linux 5.8.13-050813-generic

我看到它成功了，蓝牙USB DONGLE 5.0正在工作。

但是配对后连接有一个问题：将 Ubuntu 与我的扬声器 5.0配对后，它无法连接，然后在将 Ubuntu 与我的智能手机 LG 配对后，我无法从 Ubuntu 向智能手机发送任何图片，反之亦然。

1.我输入systemctl status bluetooth并输入。

我看到有一个问题：

2 rfkill list .：

    Hard blocked: no

我看到一切正常。

4. btmon：

5. sudo dmesg | grep -i bluetooth：

还有一个问题：

6.还有一次，我在终端上打字hcidump -X进入，然后进入蓝牙的设置，尝试配对连接音箱，在终端上得到如下结果：

Soundcore Flare+ 是扬声器的模型。我看到还有另一个问题：

蓝牙 USB 5.0 在 Windows 10 上运行良好，但在 Ubuntu 20.04 上，它不起作用。所以 Ubuntu 需要蓝牙 5.0 的驱动程序。

在 5.8.14 Kernel 上，Ubuntu 确实显示了要配对和连接的设备，但是配对和连接不起作用。

那么，谁能帮我解决这个与 Ubuntu 设备配对和连接的问题？

我在这个网站上找到了针对 Linux 的问题，但我不知道如何在 Ubuntu 20.04 上编译和打补丁，它仅适用于 Kernel 的 5.8 版。

Answer 1

Ubuntu 20.04.4 下的 0a12/0001 也有同样的问题。我的第二台计算机可以使用 debian 11 bullseye，适配器工作正常。在那里我发现了一个已安装的软件包，默认情况下 Ubuntu 20.04 中未安装该软件包。所以在20.04中尝试安装蓝牙包。适用于供应商 0a12/0001。打开终端并输入sudo apt install bluetooth
