This week I have been working on allowing for data capture completely through bluetooth transmission and ensuring that we can do so within the appropriate time constraints. Last week I had an issue acquiring data via bluetooth at a reasonable speed. Leveraging some bluefruit library functionality and using troubleshooting tests to analyze the issue, I was able to get past some initial handshake issues. Now we can successfully trigger and read 3 seconds of data collection from the IMU via bluetooth.
Progress was good this week. We have begun preliminary data collection as we intended.
My goal for this coming week is to get a full bluetooth testing suite to know what our capabilities are. Additionally, I want to get the IMU calibrated and add an option to trigger gyroscope calibration via bluetooth. Accelerometer calibration is only needed once and not again, while gyroscope calibration may be needed multiple times a session. So I will do the accelerometer calibration myself and write code to support gyroscope calibration.
