Android right Aux EEG not showing Data


#1

Hey! I’m using a Muse 2016 with the android sample app on my android phone. I want to connect an additional electrode and bought all the parts and use a micro USB on pin 4. I want to access the data trough the buffer of the EEG like this:

Log.i(TAG, “EEG - Aux” + eegBuffer[5]);

Nevertheless, when using the app and trying to access the EEG data of the right auxiliary i get the NaN (not a number) value, meaning there is no signal. Is there anything I have to do to “activate” the right Auxiliary to read any data?

Thanks in advance!

Make sure you’re using a preset that supports AUX output:

For the 2016 Muse, you want preset 20.
According to the docs, the default if you don’t set it is 21, which doesn’t have Aux.

Is it possible to get the frequency bands as well? When I want to display the alpha value it still shoes the initial value 0.0
