OBSTACLES
Our most significant obstacle was writing code that could successfully initiate bluetooth connection between the Feathers. The limitations of the Feather-to-Feather connection resulted in limitations in the KnowStroke's ability to compare readings. Furthermore, our soldering connecting the Feather and Muscle Sensor continued to break, which required continual class time to fix. Lastly, we were unable to initiate a phone call with MIT App Inventor without an individual selecting a call button. This issue would have been resolved with a GSM chip, but our order was delayed.
KNOWSTROKE'S FUTURE
In the future, we aim to improve the bluetooth and app capabilities of the device. The app should be completely independent, not requiring any user interaction to start wireless emergency communication. The device can further be minimally invasive, as the wire and component sizes are reduced.
