Bluetooth manager not working in the GUI - bluetooth adapter and DGT board detected - no pairing

[Santiago Torres]

Dear friends,

I installed all the updates for raspberry pi2 and picochess 0.33.  When, I tried to get the bluetooth connection working, the sub menus of bluetooth manager did not work in the GUI.  I could check that the bluetooth dongle seems to work and also the DGT board is detected, however I am unable to pair both devices (nor using the window terminal).  When I try to pair via window terminal, it appears many error msgs. Please, maybe some of you have some solution.

Thanks in advance for your help.

Best regards,

Santiago

What board and clock are you using?

What error messages do you get?

Do you see this in the Bluetooth Manager window?

Thanks friend,
 I am using a DGT Bluetooth Chess board with the DGT 3000.  When I use picochess with usb it works normal.  When I enter into the GUI,  I can not see that window with the device.  In fact, I can not enter to the sub menus of the Bluetooth manager.  In the weekend I will send pictures about what exacltly I am getting.

I typed some commands in the terminal window and could check that the DGT board is detected by the bluetooth device; only that.  I will print the error msg from the terminal window in the weekend.
 I dont know if the upgrade that I did to the bluetooth drivers (according to one threat in this forum from Wardy) and the fimware ugrade has something to do with the problem.? 

The initial image that I used was 0.33 with  Raspberry Pi2. Now, picochess shows 0.39 version.

Best Regards,

Santiago

For bluetooth, you don’t need to do anything. It should work automatically when using the downloaded image. However, if you upgraded the firmware, it will fail. What kernel version do you now have? The latest raspberry pi kernels break bluetooth support.

I am not at home right now, but I did that firmware upgrade with the following command

     sudo rpi-update

and also the app upgrade using

     sudo apt-get update

and also this one

    sudo apt-get install bluetooth bluez-utils blueman

Is there a way to re-do that??  Maybe installing the original 0.33 img??

Best regards,

Hallo,

try this:

hcitool scan

so you get the adress of your DGT Board (Example 00:06:66:04:FD:17)

sudo bluez-simple-agent hci0 *Adress of your DGT Board" 

now your are asked for a pairing pin

0000

now edit the rfcomm0 file

sudo nano /etc/bluetooth/rfcomm.conf

change the Adress inside the File to the Adress of your Board

rfcomm0 {

            bind yes;

            device *Adress of your DGT Board";

            channel 1;

            Comment "DGT Bluetooth Board";

    }

sudo reboot

This worked for me.

For the hcitool stuff to work, you need to downgrade the image or go back whatever is on image. If you upgrade the raspberry pi kernel, then bluetooth will break. This is due to a linux kernel bug on certain versions.

Hi friends, I had to re-install the 0.33 picochess image and update or download the bluetooth default drivers.  Then I did what bostermann said in the last email.  Now my bluetooth functionality is working.  I am seeing PIC 0.39 version.  The response is a little bit slow maybe because of the bluetooth connection.

Thanks to all,

Regards,

Santiago

If you reinstalled the image from picochess 0.33, you don't have to do anything with the GUI, it should just work on boot.

Curious why you had to.

The image seems to contain the Mac address of Jonas' DGT board. Similarly, it contains the SSID of two wireless networks that nobody else is likely to have. :)

It should attempt to scan and pair with any Bluetooth dgt board , not just Jonas's. We can fix this.

Wireless ssid, though they should not be on the image, won't affect Bluetooth pairing :)

Before updating the bluetooth drivers and doing anything, I tried scanning the board and the see if the dgt board was paired with the bluetooth dongle, but it did not work.  Therefore, I had to update (or install) the bluetooth drivers.  Maybe  my dongle was not detected by the original drivers on 0.33 image.  I did not have problems setting the wifi network, even when there are two settings there, they did not affect anything.

Oops, did I forget to delete the /etc/bluetooth/rfcomm.conf? This will break auto bluetooth connection. AAAAAAARGH ...

If you delete this file, your bluetooth dongle should connect to the board on first boot without setting or installing anything.

I'll release a new (0.39) image pronto. 

 

Similarly, it contains the SSID of two wireless networks that nobody else is likely to have. :)

Both are my home wireless networks, but as they don't interfere with Picochess operation when away, I don't bother to delete them before releasing the images.

But /etc/bluetooth/rfcomm.conf has to go.
