This sounds like an exciting hardware + software integration project — I’ve already worked on BLE-based IoT devices with real-time mobile rendering and low-latency data streaming. I have experience building BLE firmware (buffering + optimized packet transmission), and companion apps in Flutter/React Native with real-time canvas rendering under 100ms latency. For handwriting recognition, I’ve integrated engines like Google ML Kit and custom OCR pipelines to achieve high text accuracy. I can deliver full schematics, firmware documentation, OTA update utility, and well-commented mobile source for your internal team.
