user.py works but Standalone GUI doesn't: java.net.ConnectException: Connection refused

pycy

First day playing with Cyton+Daisy and just trying to reproduce the examples in Getting Started.

The Problem:
After playing around with permissions and drivers I get a blue light on the USB dongle, a working /dev/ttyUSB0, a successful connection to the Cyton card, and even raw data via OpenBCI_Python.  However, I can't get the standalone Java GUI working.

Some Extra Incidental Information:
I'm using Centos 7 (kernel is 4.8.12-1.el7.elrepo.x86_64) - my other
Centos Box running a slightly older kernel (3.10) and version of
ftdi_sio.ko doesn't seem detect the USB at all. I plan to fix that later (and advice on that welcome!).   But for now, I'd just like to see some pretty pictures.

1) The Hardware is OK:
# lsusb

2) We can connect to the Cyton (and Daisy) card:

3) We have data

Here we can even see the data get dumped and the values move around when I put my finger on the pins as per the tutorial

Only thing I don't like about this output is that it appears that I am only getting 8 channels rather than 16 I expect with the Daisy plugged in. 

4) BUT I can seem to get OpenBCI_GUI to work

The GUI starts up nicely and works with synthetic data but when I click on "Live (from Cyton)" I get:

"Unable to establish link to Hub" at the bottom of the GUI

terminal stderr output from the GUI:

Appreciate your help in advance!

pycy

OK it's "solved". 

Turns out that ./application.linux64/data/OpenBCIHub requires a fairly recent version of libstdc++.so.6 (GLIBCXX_3.4.21) and doesn't actually start up.  You can tell by running it:

./OpenBCIHub

and getting an exception.

problem was you can't really tell from the GUI stderr as the error is probably caught in a try catch loop.  When I get more familiar with this code, hopefully I can try to push some cleaner error reporting. 

I "fixed" this by using v2.2 rather than v3.01 of the GUI.

Hope this is useful for someone.
