This is the Week 4 of the Project. I worked on finishing up the system so that it would work more seamlessly. First, I worked on writing expect scripts so that whenever the STM32 sends the hex image over Bluetooth, the reciever can decode the hex bytes and store the image in JPEG format. Next, I started working on a small UI so that the user can easily control adding new fingerprints to the database/erasing the database. In addition, I am working on making the Raspberry Pi rotate a motor whenever an authenticated user scans their fingerprint and logging the timestamp of the entry to a file.
