Spent way too much time working on setting up the app to bluetooth communicate with the raspberry pi, because it turns out (after much digging) that the sample github repo I found will not work for what I need. So I started from scratch, using the CoreBluetooth framework, working heavily with the CBCentralManager class and the CBPeripheral class. Really hoping this will work this time, but not at the point of testing yet. Plan to do more work on Sunday to prepare for Wednesday’s demo.
