It gives a built in option to enable it. But bluetooth still doesnt scans anything.

Re: Bluetooth not working

Thanks for your reply.

On every boot, to start of Bluetooth, I use once:

# rfkill unblock bluetooth

then:

# rfkill list
0: hci0: Bluetooth
	Soft blocked: no
	Hard blocked: no
1: phy0: Wireless LAN
	Soft blocked: no
	Hard blocked: no

But it seems, I will have to install the wifi drivers also from the git also. Also few people seem to have success.

Re: Bluetooth not working

You have a RTL8723BE Wifi/Bluetooth combo device.  I'm sad to say, but right at this moment there isn't full support for it in the kernel.  There has been some work on the Bluetooth mailing list, but so far none of the patches have made it into git yet.

Re: Bluetooth not working

Thank you for your response.

I gave the git a try but it didnt work for me.

Any ways, should I file a bug report?

Re: Bluetooth not working

I don't know if the kernel 4.7 have the fix now but for me there are some problems too with the bluetooth, for this I used rtlwifi_new on aur and now it is correct all things, bluetooth and wifi, i am waiting for the kernel to applied this fixes in the mainline

Re: Bluetooth not working

Hi

The aur has this one:
rtlwifi_new-dkms
can kindly you confirm.


I have report bug on this, and the last update was that in Linux Mint (Live mode) there was no issue, the bluetooth ran.

But right now due to some issue with the current kernel + virtual box + firefox, I am using the linux-lts.

yes, it is the package i have installed, with this package all the functions are normal, with the stock kernel 4.6(I don't know 4.7) not fucntion without this aur package
