This week, I had fixed the bluetooth issue and connection up as well as the data encoding/decoding algorithm to work. The problem was that the bluetooth connection on Mac is always shown as disconnected but by setting the connection up manually through python code, it worked. I also have written code to distinguish between the left/right EMG data flow and combined it with the calibration code that I had before. We discussed integrating the EMG into the EEG package that is up running and will be using the similar method of triggering events from the EEG ML classification. I think I a back on track, the plan for this upcoming week is to test and integrate this into the whole system. I have discussed with Jonathan about using the FFT features but he thought our ML model classification is accurate enough, so I think we will probably add the FFT after depending on the time we have after getting the whole system up.
