What happens when you connect all three electrodes together with a blob of electrode paste or clips? You should get close to zero microvolts. What electrodes are you using, where? Has this Ganglion ever worked correctly? NONE of the tutorial steps work for you??
Nothing, zero microvolts. I've tried with BrainBay and OpenViVE but they dont recognize the ganglion. maybe i'm doing something wrong with zadig's config?
I'm confused, the screen shot above shows BLED112 dongle selected. Yet now you say you are using Zadig with a CSR dongle. And another post you asked if you should purchase a CSR dongle.
WHICH dongle do you have? When did you purchase? Has this Ganglion EVER worked on any computer?
Do you get data streaming into the GUI when you connect as shown in the tutorials? When I mentioned the "zero microvolts" test, I meant that you should see data coming into the GUI, but the graphs would show close to zero microvolts because all three leads are connected together.
Mentioning @felipev. I moved your question to this new thread, since it was not related to the "Impedance check - All electrodes appear to be floating." original thread you posted on.
Since you have the BLED112 dongle, you should NOT be using Zadig at all. If you changed any drivers with Zadig, please try to reverse that. Windows has a feature called System Restore, where you can back out any operating system or driver changes. I'm sorry you encountered this confusion. The documentation is in the process of being revised to get the Zadig info into a deprecated section. Mentioning @techsupport, @openbci, @Conor.
What are you using for electrodes? Are you able to do any of the steps in the tutorial and get signals that look ok? Your GUI picture looks like bad electrode connections, are you using the Ten20 electrode paste?
The problem was the driver that i installed using Zadig. After the system restore all is working . Although the impedance check works only sometimes. Today i bought a CSR dongle and i run Impedance check with it and it works fine. I hope this get solved in the next update.
By the way is there any tutorial that show how to use OpenVibe with the Ganglion using the LSL Widget in the GUI? I've trying all the evening but i had no luck
Same problem here, using BLED112 from the OpenBCI shop. I tried on Win 10 (latest executable and processing) and Debian based MX Linux 18.2 (processing). Curves looked OK for ECG and muscle biosensing, EEG reacted to eye blinking, not sure how well we can judge signal quality from that. Impedance check announces successful start but runs forever displaying only 0.0 for all channels.
I'm confused why your video above recommends a CSR dongle and the shop sells only BLED? Does it make sense to try using a CSR dongle? Can I just buy one from local sellers and this connects?

In the meantime I found that the impedance check using the same bled works fine on Brainbay. Might be interesting for @techsupport I guess
