A wearable connection affects much more than the code that moves data from one device to another.
While working on Vivior, the mobile app needed to communicate with the wearable device through Bluetooth Low Energy. We built custom native modules for BLE communication in React Native, while also considering the wider system around the connection: the information the app needed to receive, the stability of the interaction, and how the experience should behave across iOS and Android.
This is where technical implementation meets product thinking. A connection that drops unexpectedly, shows an unclear status or behaves differently on each platform can quickly undermine a person's confidence in the product as a whole.
Early technical decisions become stronger when the engineering team can answer three questions:
- What needs to be reliable for the user?
- Which part of the system owns the state?
- How will we investigate an issue when something goes wrong?
If your product connects hardware, mobile, and cloud services, let's talk before the integration becomes an expensive part to change.
