After spending several hours working on the report and completing the ethics assignment (before the deadline got pushed back), I spent some more time working on the Theia iOS app.  I am slowly learning how to navigate xcode, but managed to create and connect several scenes and I think I am close to having the basic flow of the app put together.  The biggest hurdle I see coming up is figuring out how to receive information from the Raspberry Pi regarding whether or not a runner is approaching. I’ve been reading a lot of Core Bluetooth framework documentation, but I don’t think I have a good enough understanding of how everything works to fully understand what I want the communication between the app and the Pi to look like. I likely will not get much done over spring break, but I intend to have the basic outline of the app completely done by the end of next week as well as some specific ideas regarding how Bluetooth communication is going to work.
