Missing Bluetooth connection

English Hardware
1

Hello,

I own a Lenovo model Y50 notebook with a Realtek Bluetooth card. I run Plasma 5 DE.
I can’t use bluetooth connection. I installed wifi drivers as suggested in this post:

https://forums.opensuse.org/showthread.php/517984-Unstable-realtek-WIFI-connection

Wifi connection works pretty well.
The problem now is bluetooth.

If I look at YaST Hardware Info I saw only a generic ‘Bluetooth Radio’ (and childnodes) under bluetooth node.

Then, if I try to open a BT connection from notification panel it doesn’t start anything.
By the way, a KDE feedback notification result, after people click on Enable Bluetooth, would have been useful.

Here is the boot log:
…
Starting Bluetooth service…
…
[32m OK [0m] Started Bluetooth service.
[32m O
[[32m OK [0m] Reached target Bluetooth.
…

Is there anything I can do to solve this issue?

I’ll report the complete /var/log/boot.log from YaST if it could be of some help:

Try updating bluez first. Add repo to Yast: http://download.opensuse.org/repositories/home:/seife:/testing/openSUSE_Leap_42.1/
Check system settings -->Bluetooth -->Bluetooth Devices. You should see something under this section.

Install the rfkill package, You can find it in the main repository. The rfkill is a small tool for accessing the Linux rfkill device interface,
which is used to enable and disable wireless networking devices, typically WLAN, Bluetooth and mobile broadband

Type: “dmesg” then “lsusb | grep bluetooth” and “hwinfo --bluetooth” (without the quotes) to review the bluetooth entries and post.

Use the hcitool in konsole to scan for connections and more.
Ensure that the bluetooth daemon is started:

# systemctl start bluetooth

To enable the daemon at boot use the command:

# systemctl enable bluetooth

If all else fails, update the kernel to a newer version as the driver code wasn’t ready when the kernel for openSUSE Leap 42.1 was released in 2015.

Update the kernel, kernel-firmware and kernel-sources to address the missing bluetooth module.

Add this repository to Yast:

This is kernel 4.6x.
http://download.opensuse.org/repositories/Kernel:/stable/standard/

Don’t forget to reboot after updating the kernel.

FYI
Your chipset is RTL8723be.

Hello,

ok, not a so trivial task! I’ll give it a try.

Thanks a lot

Hello Romanator,

ok now bluetooth is working. Both WI-FI and Bluetooth. I had to upgrade to the new kernel and firmware.

Then after rebooting I check for bluetooth daemon status with systemctl start/stop/status.
rfkill indicated bluetooth was - software blocked - and, according to rfkill docs, I did a:

rfkill unblock bluetooth

after that, the systray bt icon appeared and also in Plasma System Settings -> bt manager started working.

Thanks a lot

It’s great to here that you were able to resolve the bluetooth problem.
When it comes to wireless (especially bluetooth), “rfill” is your friend.

Write down the steps for the installation and bluetooth for future reference.
You can add it to the openSUSE Unreviewed FAQs for other Lenovo users.

Make sure that you add the model in the title for easy identification.

Good Luck!

Hello,

ok, I’ll be pleased to post the procedure.

Thanks a lot
