I have wifi and Bluetooth modules RT3290. Wifi is working fine but Bluetooth is shown as disabled under Bluetooth settings. Can anyone help me fix this?

Best Answer

I use Ubuntu 16.04 (Kernel 4.8)

Run

sudo apt-get update
sudo apt-get install build-essential linux-headers-generic

Download zip from here on GitHub and unzip it to Desktop.
Change your directory to new unzipped directory (i.e. ~/Desktop/rtbth-dkms-master).

Run the following commands one by one

make
sudo make install
sudo cp -r ~/Desktop/rtbth-dkms-master /usr/src/rtbth-3.9.3
sudo dkms install rtbth/3.9.3
sudo nano /etc/modules

Add rtbth at the end, then Ctrl+O and ENTER (to save the file) and Ctrl+x to close the editor
Reboot

Ubuntu – RT3290 Bluetooth Not Working

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.

I got the bluetooth to work!

First download the Source code from here and extract it to Home.

After that, open the rtbth_core_bluez.c file, and then go to line 86 and change it from:

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

to:

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

Go to line 216 and change it from:

    status = hci_recv_frame(skb);

to:

    status = hci_recv_frame(hdev,skb);

Then go to line 406 and change it from:

hdev->ioctl = rtbt_hci_dev_ioctl;

to:

//hdev->ioctl = rtbt_hci_dev_ioctl;

Save, then open rtbth_hlpr_linux.c and go to line 575. Change it from:

//daemonize((PSTRING)&pOSTask->taskName[0]);

(PSTRING)&pOSTask->taskName[0];

Now you are ready to Compile. Compile it in Terminal by:
```
cd rtbth-3.9.3
make
sudo make install
```
Reboot. Additionally, you can follow the PDF file contained inside this ZIP in case bluetooth still does not work.
