Week 3 Update

This week, our goal was to complete the back-end BLE scanner to receiver advertisements from our beacon. The beacon that we are using for our project is the Adafruit Bluefruit LE, which communicates with our Teensy 3.5 microcontroller; in our original plan, the administrators of meetings in our app would ideally broadcast advertisements to other listening devices. However, we are limited by the hardware of the Google Nexus 5, which does not have that capability.

We successfully built the back-end BLE scanner that receives advertisements from our BLE module at the click of the button. The original vision for our app was to have the administrators BLE beacon "wake up" our app's actions. Unfortunately, Android discontinued the Nearby Notifications API due to spammy advertisements contributing to poor user experience, as denoted in the below blog post by Android. Without this API, our implementation of the Meeting TrackR app will more likely require the press of a button from meeting attendees.
