Problem starting OpenBCI_GUI in Ubuntu 18.10

KristerKrister Sweden
in OpenBCI_GUI
Hi,

I've got a problem that I need help
figuring out a solution to. Whenever I start OpenBCI_GUI in Ubuntu 18.10
I get connection exception, see below. In the team we have seen it on 2
computers of different brands, and haven't been able to solve it for
any of them.

What is working:
- The Gui starts, and shows the Data source menu.
- When selecting Synthetic everything looks good, and I get data in the selected amount of channels

What isn't working as expected:
-
When I select Data source "LIVE (from Ganglion)" I expect a menu to
choose either wifi or bluetooth, the menu doesn't show up. If I try to
start the system nothing happens, neither in the gui nor in the logs.
- When I start OpenBCI_GUI I get logs about ConnectionException, the full log is included below.

What have been tested:
- Start with and without USB dongle
- Start as sudo and without sudo
- 2 computers from different manufacturers
-
Changing to windows on one of the computers worked. However the other
one doesn't have windows, and it haven't been tried on the other
computer

Can you please help me figure out what I'm doing wrong?

    Krister, hi.

    You mentioned using with a USB dongle, which one, CSR (old type), or BLED112 (new type). The BLED112 will give best results, it only uses a serial port.

    Have you tried running the GUI from Processing IDE?

    Hi William,

    I've tried to figure out what
    dongle it is, but I can't manage to figure it out. But I don't think
    it's relevant, I don't get far enough in OpenBCI_GUI to be able to
    choose how to connect.

    I tried to run it through Processing IDE, but with the same result. I can't find any differences in the log.

    I
    also tried to install a virtualbox image with Ubuntu 16.04, when using
    that I can open the OpenBCI_GUI and get the menu to choose how I want to
    connect to the Ganglion.

    I would be happy for any help getting further.

    Please verify that you have the BLED112 dongle. The photo in the shop shows what this looks like. In small print on the connector it says BLED112.

    If you do not have this exact dongle, then you have the older CSR dongle, which has been problematic because there are so many variations of the hardware manufacturers. The BLED112 is made by only ONE manufacturer with excellent quality control. BLED112 connects via a serial port, which is also the simplest way to get bluetooth access. The other CSR type dongles connect as bluetooth radio devices. Finally, the built in bluetooth in computers can also be problematic because of manufacturer variations.

    If you are in Sweden, then the BLED112 can likely be ordered faster through a distributor in your country, see,

    I've validate that it's the BLED112 dongle. And I've tried 2 different ones, both gave the same error.

    I checked OpenGL and the graphics as well. It's running "OpenGL version string: 4.6.0 NVIDIA 390.116", which is the latest recommended one if not the absolutely latest.

    The base error appears to be:

    "java.net.ConnectException: Connection refused (Connection refused)"

    Where the GUI is trying to start and communicate with the Hub. "Connection refused" implies some kind of permissions problem.

    Have you tried installing separately the Hub and starting it as root?



    The fact that you can run ok on Windows, means that this is some kind of glitch with your Linux setup.

    The problem was that drivers was missing. Installing arduino solved those problems:
    sudo apt-get install arduino
    This solves the problem for both wifi and USB dongle BLED112.
