I’m happy to share that the WiFi version of SugarDrive is now in a stable state and ready for people to test. If you’ve been following along and waiting for a more polished build, this is a great time to get involved.
This version lets you connect SugarDrive to a WiFi network and retrieve blood glucose data remotely. It includes all the recent improvements like configuration mode and in-field software updates—making setup and future updates much easier.
New Development: BLE Communication via iOS App
Over the past week, I’ve also been exploring a new communication path: Bluetooth Low Energy (BLE) using an iOS app.
Here’s where things stand so far:
- The SugarDrive display advertises over BLE, acting as a peripheral
- An iOS app (currently in early development) can connect to the display
- The app is able to transmit the BG value to the display over BLE
- ✅ I’ve already demonstrated basic functionality
This BLE path would allow people to send CGM data to SugarDrive without requiring a WiFi connection—offering another layer of flexibility depending on your setup or preferences.
What’s Next
- Continue refining the BLE communication—improving reliability and responsiveness
- Expand the app to handle live CGM data and make it easy to pair with the display
- Begin limited testing of the iOS app alongside the existing WiFi-based system
If you’re interested in testing either the WiFi version or the upcoming BLE version, I’d love to hear from you. Your feedback helps shape the direction of SugarDrive.
Thanks for following along!
