  • Hello. The error is pretty clear the bluetooth adapter did not get turned on in hardware. I see you are using kernel 5.13.0-39-generic. You do not mention a version of Ubuntu, you should. Maybe a newer kernel would work for you. – David Apr 03 '22 at 10:53

Issue solved:

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

Reboot. Until I can figure out what is wrong with the dkms after a kernel update you will need to

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

Reboot.

Follow Bluetooth (rtl8723be) does not find devices on Lenovo Ideapad 100-14iby
