This paper expands an Arduino Nano 33 IoT-based project into a structured manuscript that designs, implements, and evaluates a wireless IMU data transmission system between an embedded node and a computer host. The system uses the onboard six-axis inertial measurement unit to acquire acceleration and gyroscope measurements, packages the measurements into a BLE characteristic, and transmits them to a Python application through the Bleak library. Compared with the original wired USB serial approach, the BLE architecture improves mobility and supports untethered motion monitoring when paired with an independent power source. The manuscript details the hardware architecture, firmware workflow, Generic Attribute Profile service design, host-side acquisition process, packet format, timing strategy, and power-management methods. Three tables summarize the platform components, BLE design parameters, and energy-optimization methods. The analysis shows that BLE is suitable for lightweight real-time IMU streaming when connection interval, notification rate, payload size, and sampling frequency are selected according to application requirements. Remaining limitations include dependence on external power in the prototype, limited validation under long-duration use, and the need for packet-loss and latency measurements in future work.
