We have tried to see the PPG signal this morning, and that was the problem. We can see the signal perfectly in the channel A13.

If not, you do not have a secure connection between the GSR+ expansion board and the Shimmer3 mainboard. If this is the case, you should open up the unit, secure the connection between the two boards and verify functionality, before carefully reattaching the top of the plastic enclosure. Once you are sure that the PPG sensor is physically connected and turned on, you will find the signal on Channel A13, rather than channel A12, as was listed in the original documentation. Apologies for the confusion caused by this change. If you have any further technical problems of this kind, feel free to contact [email protected].
