Yes, but you need to make sure you do a write like this to enable it: https://github.com/gmierz/mindwave-lsl/blob/21827fe80f034e0a1d6b5da6b9165c6d0574ac23/test_mouse_movements.py#L19

but I tried it is not possible to get raw EEG data

I'm using another single electrode FT$S mind link EEG Headband, is it any method to receive live raw EEG data from it
