Hi everyone,
Recently just purchased a chuwi minibook x to just have a play on linux, im really enjoying manjaro so far, definitely my favorited distro ive come across, especially with gnome!
I apologise for my lingo upfront im still coming to terms with the terminology!
Ok so i have no bluetooth essentially, i try turning the radio button on and it flicks right off and does nothing.
Ive tried a couple of things from forums but nothing. (rfkill unblock bluetooth) and tried restarting the service but nothing.
Wondering if it could be a limitation of my minibook hardware?
Cheers,
Probably check this:
sudo dmesg | grep -i bluetooth
So that leads me directly to this old bug: https://bugzilla.kernel.org/show_bug.cgi?id=215167
$ errno 110
ETIMEDOUT 110 Connection timed out
Basically, it means that the device is not fully initialized when the driver connects to it and the driver doesn’t wait long enough.
Maybe reloading the driver:
sudo systemctl stop bluetooth.service
sudo modprobe -rv btusb && sleep 10 && sudo modprobe -v btusb
sudo systemctl start bluetooth.service
Let a second terminal open and monitor dmesg:
sudo d…

Thanks for the reply, so i followed what was mentioned in that post, im getting this on the dmesg

Looks like the requested firmware for your device is not there.
When I read this: https://community.intel.com/t5/Wireless/AX101-Linux-driver/td-p/1465559 It seems that a symlink of
ibt-1040-4150.ddc → ibt-0040-1050.ddc
ibt-1040-4150.sfi → ibt-0040-1050.sfi
cd /usr/lib/firmware/intel
sudo ln -s ibt-1040-4150.ddc ibt-0040-1050.ddc
sudo ln -s ibt-1040-4150.sfi ibt-0040-1050.sfi
Make it work.

Wow thank you, those commands fixed it, this might be naive of me but as a new guy would you mind explaining what that is actually doing?
It simply creates a symbolic link of each file. So when the module searches for ibt-0040-1050.sfi it will find it, but open ibt-1040-4150.sfi.

Or an upgrade to the kernel 6.5 could have a fix for that, as one mentioned that an upgrade to 6.4-rc7 fixed it.
