No meaningful data from Ganglion - is it broken?

Tricent

Hello everybody,

I recently received my Ganglion Board, but are unable to get meaningful data from it.

I followed the tutorial instructions, but as I start the data stream (not plugged to any sensors) I

- get rubbish noise values in the time series

- get fixed values for the accelerometer (as soon as I start all three values become -1,376g and do not change even if I move the board)

Below is a screenshot of the gui:

I have done the tutorial on a desktop pc with Windows 7 and on a laptop with Windows 10 - same results.

Especially the fixed accelerometer values seem odd to me.

Besides, when I use the headset and connect the electrodes to the board and execute the impedance test, it does not do anything. The logo appears and nothing else - no progress or anything.

So, any ideas what I am doing wrong. Or is my board broken by arrival?

Kind regards and thanks in advance

The maxed out accelerometer is disconcerting.

I would expect that if the inputs are not connected to anything that you would get something undesireable, but the accelerometer values should never do that.

Please email contact-at-openbci-dot-com, and we will see if we can't figure out what the problem is.

I realized I am also facing the same problem. I did not check the accelerometer but now when I did it appears exactly like here.
