Cyton Bluetooth 2.0 (HC-05) Adapter Board
Dear community,
I'd like to share with you my simple adapter design that connects a HC-05 bluetooth module to the Cyton board and therefore gives you the possibility to use it without the dongle on several platforms and higher sampling rates. I even found that converting to BT2 improves reliability of the system.
Github repo:
https://github.com/BigCorvus/OpenBCI_Bluetooth2adapter
The GUI 2.0 is able to keep up with a 500Hz sampling rate at 8 channels and 250Hz at 16 channels. Of course the FFT parameters and many others are incorrect but this can be adjusted by modifying the Processing code. Streaming into MATLAB also works fine @ 500Hz and 8 ch.
Greetings,
Arthur

after reading the instructions I think that the best way for me to contribute would be directly via my Wordpress blog.
