蓝牙键盘在 OSMC Linux 上未被识别为输入设备

  • 772

我正在尝试将G7BTS蓝牙遥控器/键盘连接到运行 OSMC Linux（版本 5.15.92）的 Raspberry Pi 4B。设备似乎已连接，但未检测到输入。

这是我所做的：

我使用连接bluetoothctl

[bluetooth]# scan on
<....>
[NEW] Device XX:XX:XX:XX:XX:XX G7BTS
[bluetooth]# pair XX:XX:XX:XX:XX:XX
[G7BTS]# trust XX:XX:XX:XX:XX:XX
[CHG] Device XX:XX:XX:XX:XX:X Trusted: yes
Changing XX:XX:XX:XX:XX:X trust succeeded
[G7BTS]# connect XX:XX:XX:XX:XX:XX                                                                                                                                                                               Attempting to connect to 36:36:05:E1:BE:42
Connection successful

我检查了输入设备

该设备未显示在 /dev/input/ 或 /proc/bus/input/devices 下。仅列出了我的其他 Logitech 外围设备。

osmc@osmc:~$ ls /dev/input/
by-id  by-path  event0  event1  mice  mouse0
osmc@osmc:~$ ls /dev/input/by-id/
usb-Logitech_USB_Receiver-if01-event-kbd  usb-Logitech_USB_Receiver-if01-event-mouse  usb-Logitech_USB_Receiver-if01-mouse

我也没有看到该设备/proc/bus/input/devices（列出了其他 Logitech 设备）


到目前为止我已经尝试过：

  1. 已安装 BlueZ 包
sudo apt-get install bluetooth bluez bluez-tools
  1. 已加载的 HID 模块：
sudo modprobe hidp
sudo modprobe hid
  1. 暂时禁用 ERTM
sudo bash -c 'echo 1 > /sys/module/bluetooth/parameters/disable_ertm'
  1. 在我的电脑上测试了遥控器（没有问题）
  2. 更新了系统
  3. 在 Pi 上测试了蓝牙鼠标
  4. 移除了罗技外设
  5. 使用另一个 USB 蓝牙适配器
  6. 重新启动系统（多次）

为什么我的 G7BTS 蓝牙键盘无法识别为输入设备？是否有其他步骤可以使其工作？我可以强制将其变为 HID 设备吗？

提前谢谢您，我们将非常感谢您的帮助。

    升级 BlueZ 解决了该问题

    升级到较新版本的 bluez 后，问题已得到解决。Apt 的版本是，从kernel.org5.64切换到 后，问题已得到解决。5.79

    构建和安装新版本 BlueZ 的步骤

    1. 删除旧版本
    sudo apt purge bluez
    1. 安装依赖项
    sudo apt install libdbus-1-dev libudev-dev libical-dev libreadline-dev libell-dev libglib2.0-dev python3-docutils

    如果尚不存在则构建工具

    sudo apt install build-essential
    1. 从 Kernel.org 下载并解压 bluez
    wget https://www.kernel.org/pub/linux/bluetooth/bluez-<version>.tar.xz
tar xvf bluez-<version>.tar.xz
cd bluez-<version>
    1. 构建和安装
    ./configure --prefix=/usr \
            --mandir=/usr/share/man \
            --sysconfdir=/etc \
            --localstatedir=/var \
make
sudo make install

    然后重启系统并尝试连接键盘。就我而言，一切运行正常。
