联想 Ideapad 100-15IBY 蓝牙未发现任何设备

我的系统是联想 Ideapad 100-15IBY。我打开了蓝牙，但没有发现任何设备。

答案1

问题解决：

sudo apt install git dkms
git clone https://github.com/jeremyb31/bluetooth-5.4.git
cd bluetooth-5.4
make
sudo cp btusb.ko /lib/modules/$(uname -r)/kernel/drivers/bluetooth/btusb.ko

重启。在我弄清楚内核更新后 dkms 出了什么问题之前，你需要

cd bluetooth-5.4
make clean
make
sudo cp btusb.ko /lib/modules/$(uname -r)/kernel/drivers/bluetooth/btusb.ko

重启。
