Connected Devices & IoT

Hardware Meets
Software

We build companion apps that connect physical products to mobile devices. BLE pairing, firmware updates, real-time telemetry, device management. All from one Flutter codebase on iOS and Android.

From cycling drivetrains to EV charger dashboards. If it has Bluetooth or an API, we can connect it.

IoT in Production
4 BLE hardware types managed in one Flutter companion app.
OTA Firmware updates pushed to devices without service visits.
60fps Rendering 100 live auction clocks on Lava's real-time bidding platform.
2 Wireless drivetrain protocols integrated (Shimano Di2, TRP CMD).

What We Build for IoT

BLE Companion Apps

Device pairing, characteristic reading, encrypted communication, multi-device management. The Classified Cycling app manages 4 hardware types over Bluetooth Low Energy.

Firmware OTA & Device Management

Push firmware updates to devices in the field. Nordic DFU integration, version management, rollback support. No service center visits required.

Real-Time Dashboards

Live telemetry from sensors, chargers, or industrial equipment. The Xplore Group charger dashboard runs on Raspberry Pi with Flutter at 60fps.

Hardware Protocol Integration

Shimano Di2, TRP CMD, custom BLE protocols. We've integrated wireless shifting systems, implemented challenge-response authentication, and built bonding flows for multiple device types.

Our IoT Projects

Why Flutter for IoT?

Cross-Platform BLE

One BLE library covers iOS and Android. Scanning, pairing, encrypted characteristics, firmware OTA. No stitching together platform-specific packages.

Embedded & Desktop

Flutter runs on Raspberry Pi, Linux kiosks, and Windows desktops. The same rendering engine powering your companion app can run on the device itself.

Real-Time Capable

WebSocket streams, MQTT subscriptions, BLE notifications. Flutter's reactive architecture handles real-time data natively without polling or workarounds. Lava's auction platform streams 100 price points with 20 updates per second over WebSockets at 60fps.

Insights

How We Integrated Shimano DI2 into a Flutter BLE Companion App
How We Integrated Shimano DI2 into a Flutter BLE Companion App
Classified Cycling joined the Shimano Connected Partners program. We built the mobile-side D-Fly protocol integration that lets riders pair their DI2 shifters with the Classified Powershift Hub through the app.
Vistar // Powershift: Integrating TRP's CMD Protocol in the Classified App
Vistar // Powershift: Integrating TRP's CMD Protocol in the Classified App
When TRP and Classified launched the Vistar // Powershift groupset, we built the mobile-side integration that connects TRP's CMD wireless shifters with the Classified Powershift Hub through the companion app.
