Problems with saving data file using brainflow

[larastellamarie]

Hello,

I am currently trying to record data with the Muse 2 using the SSAEP experiment and a MMN experiment. When I run them apart using brainflow everything goes fine. Now I tried running the two experiements shortly after each other which results in only one data file being saved. The other experiment runs but does not save a data file in the end and produces this error:

If I use bluemuse everything works fine. I don´t think that it has anything to do with the order (sometimes the first experiment elicits an error and sometimes the second) or the experiment itself. Any advice how I can avoid this problem?

Hey, @larastellamarie , is this error still occurring for you?

Hey,

I don´t know, I am sorry. I switched to using Bluemuse after brainflow didn´t work for me but I am encountering new problems for which I opened a new issue
