The goal is to create a small, robust sensor device that includes an IMU unit, accelerometer, gyroscope, battery management system, and Bluetooth connectivity, among other features. The device will store data locally and transmit it via Bluetooth, Support over-the-air (OTA) updates, and NFC pairing. Hardware Requirements --------------------- - IMU unit: Accelerometer and Gyroscope - Battery Rechargeable Lithium-ion Battery: Long-lasting and compact, suitable for frequent recharging. Battery Management System (BMS): Ensures safe charging and discharging. Charging Port: USB-C for recharging. - LED indicator Status LED: Indicates power, connection status, and low battery. - Microcontroller Low-power Microcontroller: Manages sensor data processing and communication. **See if we are using IMU with sufficient MCU already. - Data Storage Internal Flash Storage: For storing sensor data when not connected to the app. - Bluetooth Connectivity for connectivity and data transmission - WakeUp Detection Activate the device when motion is detected to save battery life when not in use. - NFC Tag Enable Bluetooth Pairing Via NFC Tag Software Requirements ---------------------- - Ensure data readings are stored in internal flash memory and easily transferable via BLE (in real time) / via USB for manual export (Manual Export Feature should be configurable). - Communication via SDK, BLE + Enable two way communication support. - OTA Updates Support Enables firmware updates over the air to keep the device software up-to-date. - While using bosch fusion sensor tech software, ensure we are also sending data processed from it. Like step count, activity recognition, etc. Example: [login to view URL] Final Deliverables ------------------ - A working PCB along with Design. - Updated Firmware - Data Output should have a. Step count algorithm result inbuilt in BOSCH sensors (Calibrate/tune the sensors for the correct results b. Activity recognized c. Raw Accelerometer and Gyroscope Data d. Pre Meta Information (like device ID or any that we will share with you explicitly) e. Repetition Count (this is also built into the BOSCH’s sensor software**) (open to discussing the approaches to achieve it) Note: We prefer BOSCH's latest sensors, open to other sensor recommendations and comparisons. Added advantage of delivering a basic app to interact with the above device. If the sensor needs to be shipped to you, we can handle it.

Dear Client, With over 30 years of experience in PCB design, electronics design, and circuit design, I am excited to develop your motion tracking sensor device. My approach includes designing a compact and robust sensor device that integrates an IMU unit, accelerometer, gyroscope, battery management system, and Bluetooth connectivity. 1. I will integrate an IMU unit (accelerometer and gyroscope), rechargeable lithium-ion battery, battery management system, USB-C charging port, LED indicators, and a low-power microcontroller. Ensure robust PCB design to house these components effectively. 2. I will utilize Bosch's sensor fusion software to enhance data accuracy and support step counting, activity recognition, and raw data collection. 3. I will develop functionality for local data storage in internal flash memory, real-time BLE data transmission, and manual export via USB. 4. I will enable reliable Bluetooth connectivity for data transmission and incorporate NFC for easy pairing, ensuring user-friendly operation. To learn more about my expertise, please see my profile visit: https://www.freelancer.in/u/HarimohanG Question: Q1. Are there any specific requirements for the OTA update mechanism or the BLE communication protocol? I am enthusiastic about contributing to your motion tracking sensor device project and look forward to discussing how we can achieve your desired outcomes together. Best Regards, Hari Mohan

We can use BNO-085 or 086 with in built sensor fusion and step counter. And for MCU nRF52832 will be perfect. It is very low power and supports NFC. I also have a lot of experience with BMS and PCB design. Let me know. Best regards. Pathum

With my extensive experience developing embedded software for various industries, I fully understand how to bring your Motion Tracking Sensor Device project to fruition. I am well-versed in all the major microcontroller platforms and have a significant background in firmware development. I know how to integrate sensors like accelerometers, gyroscopes and IMUs into embedded systems and ensure smooth communication with the targeted hardware. Additionally, my knowledge of both C and Python will be invaluable in tuning the BOSCH Fusion sensor software for accurate step count outputs, activity recognition, and delivering raw accelerometer and gyroscope data as well. Designing PCBs is also one of my core strengths and I always pay careful attention to detail. A working PCB along with updated firmware that supports OTA updates and enables data storage in internal flash memory for future USB exports are non-negotiable deliverables - ones that I can guarantee you right away. My familiarity with battery management systems also positions me well to design a device that's power efficient while still providing optimal performance even during motion detection waking up. Plus any additional features in the project will not be an issue. In conclusion, my ability to seamlessly integrate different sensor technologies and optimize their usage along with a solid track record turn me into a strong candidate for your project.
