I have a Lenovo G50-30 laptop. It has a qualcom AR9565 wlan + AR3012 bt combo card. The wifi works fine. The bluetooth when turned on doesn’t stay on. A view over the logs shows that "hci0 failed to disable LE scan:status 0x1f. This has happened in ubuntu based distros as well so it seems to be hardware specific. I have found other threads about the particular chip on popOS github. What I think this has to do with is broadcom drivers, since the official lenovo page does state “Atheros,Realtek,Broadcom” in their driver installer. I might be wrong since others with broadcom cards couldnt even get wifi unless they manually installed the driver. I would appreciate any help there is and I am just wishing to make this issue more known for the improvement of linux.
One thing that will allow us to aid you better would be if you were to post the output of lspci -nn. That will tell us exactly what devices are installed and the chipset IDs so appropriate drivers may be identified.
The output of inxi -Fxx will also assist with the task.
Have the same problem.

That part from the inxi output shows the bluetooth device is USB attached with chip ID 0cf3:3004 using driver btusb.
A quick search for that chipset and drivers in fedora shows there are 2 possible drivers that may work. ath3k and btusb.
The search was done with 0cf3:3004 driver fedora and one of the first links was this one
So how do I test the ath3k driver?

It shows ath3k in bluetooth modules. So is it possibly not a driver issue?
lsmod | grep btusb will give you eight different places where btusb is used.
lsmod | grep ath3k will only give two.
Since that shows that both are loaded I am not sure what the issue may be that is causing the intermittent actions. It is possible that the modules are interfering with each other but I will have to leave it to someone with more experience with bluetooth to help in identifying the actual error cause.
