How to enable bluetooth using Lenovo 480G

February 15Hits:1
Advertisement

This has been mentioned before for different Lenovo models (here: How do I enable Bluetooth on my Lenovo IdeaPad Z580?).

The toggle switch shows off, switching it on does nothing, different BT dameons do not work either. There was a suggestion to upgrade the kernel to 3.7* (I am running 3.6* now), but when I did this, I could not figure out how to get wired network driver support. My mistake for getting a Lenovo, looks good, but the linux support seems to be lacking.

rfkill list 0: ideapad_wlan: Wireless LAN     Soft blocked: no     Hard blocked: no 1: ideapad_bluetooth: Bluetooth     Soft blocked: no     Hard blocked: no 2: phy0: Wireless LAN     Soft blocked: no     Hard blocked: no 

Any suggestions how to get the bluetooth enabled?

I use a Lenovo ThinkPad X200 Tablet and Bluetooth is working for me. Maybe this will help you.

I use bluez (4.101-r5) and have the daemon start at the default runlevel by OpenRC. For connecting to devices, I use the applet from gnome-bluetooth (3.6.1). Once you get that installed, it should add a "Bluetooth Settings" section to your Gnome Control Centre.

Here's some additional info.

rfkill:

$ rfkill list

4: hci0: Bluetooth
