When doing a EDA test in our constructed Bitalino device (Revolution BLE/ Freestyle), we obtain data in OpenSignals. However, I have to do a vigorous activity to make the graph appear as peaks and valleys. When I stop, the graph reverts to a relatively flat line.
The point is, the data acquisition appears to be quite extreme: if I do a relatively medium activity (like walking on the spot) I get no data shown.
We have connected/reconnected device, and even re-soldered our board. We use Bitalino pre-gelled electrodes.
Can you advise where I should be troubleshooting? Thanks.
