# Ubuntu – RT3290 Bluetooth Not Working

I have an HP Envy H8-1437c system and my bluetooth is not working. I am running Ubuntu 13.04 with kubuntu-desktop installed. This is a UEFI system, but legacy boot is turned on.

I have a Ralink RT3290 wireless and bluetooth card, and the wireless works fine. When I go to the bluetooth settings in KDE, I am told that no bluetooth adapters were found.

Here is one part of the output of lspci -v:

03:00.1 Bluetooth: Ralink corp. RT3290 Bluetooth
Subsystem: Hewlett-Packard Company Device 18ec
Flags: fast devsel, IRQ 11
Memory at f7200000 (32-bit, non-prefetchable) [disabled] [size=64K]
Capabilities:

And rfkill list:

0: phy0: Wireless LAN

  Soft blocked: no
Hard blocked: no


As you can see, bluetooth simply does not show up. I know that my computer is capable of using bluetooth; it worked before I wiped Windows and it is clearly advertised on the box that the computer came in.

I tried downloading the driver for the bluetooth card from http://downloads.zotac.com/mediadrivers/mb/download/NB087_Ubuntu.zip. When I follow the instructions from here, I get stuck at the first step. Here is the output of the make command when I am in ~/Downloads/rtbth_v3.9.3/rtbth_v3.9.3:

I do not know why I cannot build the package. Based on other people's reports, the driver works once you build it. I need the rtbth.ko file to put into /etc/Wireless/RT3290. Please help me get my bluetooth working… Thanks!

Edit: I just read another AskUbuntu post about this, with the same problem as me. Please see here. I am wondering if I can somehow download the rtbth.ko file from somewhere, since that is really all I need to get bluetooth working… I appreciate any help on this topic. I know I could switch back to Ubuntu 12.04 LTS, but I really can't because there is software on Ubuntu 13.04 that I need for work… Thanks again!

• There's a fix to this problem which I will explain here (source)

modify rtbth_core_bluez.c line 406 and just comment out this line.

//hdev->ioctl = rtbt_hci_dev_ioctl;


then change rtbth_core_bluez.c line #216 and comment out the original line, replacing it with:

//status = hci_recv_frame(skb);
status = hci_recv_frame(hdev, skb);


after that, you need to change rtbth_core_bluez.c in line 86 and make these changes (is it clear?)

//int rtbt_hci_dev_send(struct sk_buff *skb)
int rtbt_hci_dev_send(struct hci_dev *hdev, struct sk_buff *skb)
{
//struct hci_dev *hdev = (struct hci_dev *)skb->dev;


after making these changes you should be able to compile and add your BT devices, although I never managed to add a device myself.

by the way, the patch provided inside the link does not work and you have to do this by yourself.
