Impedance Check Not Working, Ganglion. [resolved]
Hi all! I got a Ganglion board, the EEG headband kit, and some EMG electrodes (the Low-Cost Biosensing Starter Kit) recently. I went through the Ganglion tutorial a few weeks ago and just tried out the EEG headband. As I was troubleshooting that today, I tried to check the electrodes' impedance, but the "Check Impedance" widget didn't work. Every time I used it, it started successfully (or so it claimed), but it never produced output--it just ran until I stopped it. In some cases, this was upwards of 2-3 minutes. Now that I think about it, I don't remember it working when I first set up the Ganglion either. Does anybody have an idea as to what the problem might be? Any advice would be greatly appreciated!

Use a newer version of the GUI.
Dear tech support, community,
The impedance check is not working for me, even with the new GUI version.
The error I suppose I get is:
"Code 414 Error: Unable to write to BLED112 attribute".
I am on a Linux 64, Ubuntu 16.10, OpenBCI_GUI 4.1.2.
I suppose is something to do with permissions, but I have no idea of what and how.
Thanks in advice for helping.
Kind Regards
Matteo Mazzanti
