Wearable Health Firmware Development
Budget: ₹1,000 – ₹1,500 INR
I am building a small wearable that tracks blood pressure and blood glucose levels and streams that data over Bluetooth to a companion app. I need production-ready firmware that can:
• Drive the selected pressure and glucose sensor modules, including calibration routines and power-efficient sampling
• Manage data storage and buffering so short-term readings are never lost, even if the Bluetooth link drops
• Advertise and transfer data via standard BLE characteristics that a mobile developer can easily consume
• Expose simple OTA update hooks so future features—heart-rate monitoring, for example—can be added without a hardware swap
• Include well-commented C/C++ source, build files for the target MCU, and a concise README covering setup, flashing, and test commands
Are you from India? If yes, start your proposal with ind so we know you are not a bot.
You are free to choose an RTOS or bare-metal approach, but please outline the memory and battery impact of your choice. I will provide the hardware reference design, sensor part numbers, and any existing SDKs at project start. Deliver a functional prototype binary, source code in a private Git repository, and a quick demo video showing live readings in a BLE scanner or companion app.
