在我的 wifi 恢复工作后（RLT 8822BE 无线问题）我的蓝牙仍然有问题。它与 wifi 的设备相同，是 Realtek RTL8822BE。我安装了内核 4.14。不知怎么的，它就在那里。作为
$ sudo lshw
显示：
*-usb:1
description: Bluetooth wireless interface
product: Bluetooth Radio
vendor: Realtek
physical id: 5
bus info: usb@1:5
version: 2.10
serial: 00e04c000001
capabilities: bluetooth usb-2.10
configuration: driver=btusb maxpower=500mA speed=12Mbit/s
所以 - 我不知道该怎么办。我发现： https://github.com/torvalds/linux/commit/1110a2dbe69831abdcf119c3a9a4c4ef2d0905f8#diff-73c18c51833f458295d18481beb9507aR37
但不知道如何处理它...
你能帮助我吗？

看起来很可疑，不是吗？
有任何想法吗？
当我尝试时：
$ dmesg | egrep -i 'blue|firm

..超过 10 分钟什么也没有发生。

实际上问题可能是你安装的没有蓝牙固件，在终端中执行
cd /lib/firmware/rtl_bt
sudo wget https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/plain/rtl_bt/rtl8822b_config.bin
sudo wget https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/plain/rtl_bt/rtl8822b_fw.bin然后关机再开机
