Innobiosystems CGM
Flutter BLE tools for continuous glucose monitoring, native mobile integrations and nRF52 firmware work.
Task
Collect and inspect sensor readings on iOS and Android while making the BLE and signal-acquisition path observable during development.
My contribution
Built Flutter applications, BLE discovery and data handling, plots and CSV export. Worked with native iOS integrations, nRF52832 acquisition firmware, sampling/averaging and raw measurement windows.
Technical decisions
The firmware work spans nRF5 SDK 17.1 / FreeRTOS and migration work toward Zephyr 4.1, including SAADC, power behavior and hardware debugging. Bench and Fly provide application interfaces. A separately labeled explanatory diagram illustrates the signal-processing stages.
