BrainBay

hi,
I am glad BrainBay v.2.6 support BrainFlow-compatible devices as sources.
Anyway, it seems it doesn't support MUSE 2016 BLED, even if could be supported through the BrainFlow library.
(https://brainflow.readthedocs.io/en/sta ... -2016-bled)
Any chance to have it supported in future BrainBay releases?

TLTR;
I give neuro-feedback sessions during science/art happenings by using BrainBay.
I have a MUSE 2016 and OpenBCI Ganglion devices.
The latest version of OpenBCI_GUI (5.0.9) has removed OpenBCI_Hub.
Even so, I can still use OpenBCI Ganglion BLED as source in BrainBay, thanks to BrainFlow library support.
However, by using a MUSE 2016 BLED my sessions would be more children and tide-time friendly.

Thanks
Matteo Mazzanti

hi Matteo,

sorry this took so long..

I just updated the Brainflow integration into Brainbay and added support for the devices which recently got Brainflow compatible
Please try the new release Brainbay v2.7: https://github.com/ChrisVeigl/BrainBay/releases/tag/v2.7
Hopefully your MUSE 2016 BLED should work now!

Great that you apply Brainbay/NFB in science/art related setups!
Would be great if you want to share more information about that,

best regards,
chris

Hi Chris,
first of all, thank you very much for all your work.
BrainBay is a great door-opener and a real neurotech catalyzer.
A lot of fun with it!

I have downloaded BrainBay 2.7 and tried to connect MUSE2016-BLED with BrainFlow, on Linux.
No success.
BTW, the COM settings is grayed out.

As a test, I have tried by using BrainFlow v5.3.0 (python binding) and it worked.

I will try MUSE2016-BLED (BrainFlow) with BrainBay 2.7 on Windows and come back.

I also created a symlink in
/home/[USER]/.wine/dosdevices/
that link com1 -> /dev/ttyACM0 (my-bled-device).
But still no success.

I'm sorry I can't help much with this issue, because as I don't have the HW for testing ...
the error message is not very helpful either!

does it work under windows?

hi Chris,
> does it work under windows?
same on Windows.

I looked for the BrainFlow error:
https://brainflow.readthedocs.io/en/stable/UserAPI.html?highlight=error#_CPPv4N9brainflow18BrainFlowExitCodes14SET_PORT_ERRORE

Code: Select all

SET_PORT_ERROR = 3

It seems related to wrong serial port set.

Maybe you could enable the port input in BB UI (so user can insert a value) and pass the value to BrainFlow, as, i.e., for the BrainFlow OpenBCI Ganglion board.

hi Matteo,

I enabled the COM-Port selection for the Muse 2016 BLED device - thank you for the hint that this was missing!

please try the new .exe from github:
https://github.com/ChrisVeigl/BrainBay/ ... ainBay.exe

(replace the old .exe)

does it work?

[matteo_mazzanti]

hi Chris,
it doesn't, but it throws a different error message (finally some progress!)

First, it throws a
SYNC_TIMEOUT_ERROR = 18 (from brainbay)

Second:
I checked on terminal the linux device associated with the BLED and it has crashes,
and it gets automatically re-assigned to a new port.
So if before it was /dev/ttyACM0
it is now /dev/ACM1

Not sure what is going on here.
Maybe we should call in Andrev.

yes - looks like i can't do much from the brainbay side...
did you already post the issue in the Brainflow slack channel?
