Hello Mou'men Alnemrat,
my name is Roberto Meattini, and I am a PhD student at the University of Bologna, Italy. I was looking at your project of connecting the OBCI board to an android phone, congratulation for that very nice achievement!
I am writing to you because I bought a OBCI board (8-ch 32 bit) for research purposes regarding human neural intention decoding from EMG signals, to control robots (prosthesis and exoskeletons). For such purposes, I need a higher online sample rate: 1 kHz instead of 250 Hz. To do this the only possible way is connecting to an external bluetooth, as you did in your project. I am really interested in implementing such connection between the OPBCI and an external bluetooth module, and since I have not clear some aspects of the connections and of the modifications in the OPBCI firmware, I kindly ask if you could give me some help.
Thank you in advance for your kind interest.
