Ganglion impedance check not functioning

snowshoes12 · December 2018

I have a ganglion, and I'm getting readouts for all 4 channels for neuro but upon checking impedance, no results are shown. Has anyone else seen this problem? I'm using a bled 112 dongle.

Eric, hi.

I do see there is a old issue, supposedly resolved and closed,

https://github.com/OpenBCI/OpenBCI_GUI/issues/209

Are you running the latest GUI / Hub / Ganglion firmware? When did you purchase your Ganglion?

Regards,

William

Yes on newest GUI, hub releases. Purchased less than a month ago.

I have the same issue. I click impedence check and the results are never shown. Using ganglion with four electrodes.

@Sebperalta and @snowshoes12, hi.

Can you both please visit this Github issue and log more specifics about what operating systems, dongle, GUI and Hub versions, standalone or not, etc. See the original issue template for suggestions of info to supply.

On the issues page, Richard Waltman (forum name @retiutut ), says that he is not seeing the impedance problem with the current 4.0.3 GUI.

Can @Sebperalta and @snowshoes12 PLEASE confirm you are running the latest GUI and Hub, and retry your impedance check? And add your own comments to the issue page.

I'm not sure where it states which version I have. When I select update it takes me to https://github.com/OpenBCI/OpenBCI_GUI/releases/tag/v4.0.2

How do I check my version and/or update to v4.0.3?

What about OpenBCIHub is there a link for the latest version of that? Or is it deprecated

wjcroft · January 2019

The link above states:

Use OpenBCIHub v2.0.3 please.

Which is here,

I have confirmed the same phenomenon.

However, this phenomenon has been confirmed only when BLED 112 dongle is used.
Also, when I connect with Ganglion using CSR dongle, impedance can be measured without problems.

Here is my environment.
GUI v 4.0.4
Hub v2.0.5
OS Windows10

Thanks,

@Otemo ;""However, this phenomenon has been confirmed only when BLED 112 dongle is used.""

This is correct, and this data is consistent with BLED112 on Mac.

Looking into a fix!!!
