Currently, the most significant risks to this project include understanding and correctly using the BlueZ development stack, which provides support for Bluetooth layers and protocols. These risks are being managed by extensively reading documentation and finding relevant projects using BlueZ. One contingency plan we have ready is to use a Wi-Fi webserver to communicate between the phone and the RPi Zero W instead of Bluetooth.
Currently, no changes have been made to the existing design of the system, as we have been primarily focusing on the current design for our Design Review Presentation.
Our updated schedule can be found here. The most notable changes we’ve made to our schedule include creating a separate section for our learning system and subtasks for it, as well as including usability testing for our system.
