A PoC for displaying next calendar event on oLED from your macOS calendar through BLE
Summary
This small SwiftUI project integrates EventStore and CoreBluetooth to send notification to your IoT device. In this case I’m using oLED to display next event and adding a buzzer to notify me.
You can integrate with your own device by modifying the UUID in BLEManager.swift
Demo
Please notice that you have to write code to handle BLE connection and receiving the message.
