Hi i was wondering if you have some tips about getting a better quality connection... here is the problem: sometimes everything works fine and i have really nice quality which drops to poor for some seconds but comes back to normal.. but sometimes it suddenly stops connecting and the mindflex keeps trying to calibrate the headset but can't... is there something i can do? i have my laptop unplugged from the wall outlet...

Hi!
I tried the sketch with a Mindwave Mobile 2 on both Mac and PC with Processing 3.5.4. The application always crashes after 4 packets received.
This is part of the console log:

Error, disabling serialEvent() for /dev/tty.MindWaveMobile-SerialPo null

Are the strings I receive correct? Why does an error always come after the first packets?
Thank you in advance for the suggestions you can give me.

Hi, I resowed my arduino/mindflex garden and now running BrainGrapher fails in processing 2.0.3 with Cannot find a class or type named "channels". The arduino/mindflex are def providing high in fibre serial output. Seems to be a broken path or wrong file? Does controlP5.jar also require updating in the processing library hierarchy?

Best

I followed every single step but for some reason even though I can see the bars moving up and down in processing, the graph section (line graph) is empty. It's not showing anything. I'm using the hack on a mindflex head set.

Arduino: 1.0.5
Processing: 2.0.1
ControlP5: 2.0.4

Do I need to download something else besides those three things? Thank you!

specific brainwave Neurofeedback implementation please

Gamma has been found to be the most significant marker for meditation https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5261734/

ie when gamma going up music gets louder

if gamma goes down music volume gets lower

Or when gamma has reached a certain value a tone is produced
