Question

I run this command:

uname -r; lsusb; lspci -nnk | grep -iA2 net; rfkill list all; hciconfig -a; dmesg | egrep -i 'blue|firm'

this is the output:

The machine is an ASUS laptop, using Xubuntu 18.04.1 LTS

I installed the drivers for the wifi (MT7630E) and somehow they work (sometimes I need to reinstall them) but I was never able to get the bluetooth running, can you please help me? Thanks

Solution

I put a patch based on what you found on my github, to install do

sudo apt install dkms git build-essential
git clone https://github.com/jeremyb31/newbtfix-4.15.git
sudo dkms add ./newbtfix-4.15
sudo dkms install btusb/4.0

Check results for mokutil --sb-state if it says Secure Boot is enabled, then Secure Boot will need to be disabled when you reboot, if it says Secure Boot disabled, mokutil not installed, or system doesn't support EFI variables, just reboot

What happens if you sudo hciconfig hci0 up

Hi @Jeremy31, thanks, this is the output: Can't init device hci0: Invalid request code (56)

I found this guide but I don't understand what it means by "cd to your preferred build dir". What directory is the guide talking about?

sudo dkms install btusb/4.0 Kernel preparation unnecessary for this kernel. Skipping... Building module: cleaning build area.... 'make' all KVER=4.10.0-38-generic....(bad exit status: 2) ERROR (dkms apport): binary package for btusb: 4.0 not found Error! Bad return status for module build on kernel: 4.10.0-38-generic (x86_64) Consult /var/lib/dkms/btusb/4.0/build/make.log for more information. I am not an expert on this matter. So I will leave you with this.

@JaydeepW the 4.10 kernel is EOL, install 4.15
