Hi Dear, We will review your microcontroller firmware and hardware interfaces, align BLE communication, sensor polling, power management, and OTA workflows, and identify any timing or integration issues. We will design and execute functional, stress, and regression test suites, using tools like logic analyzers and automated scripts where applicable. A detailed test report with logs, pass/fail results, and recommendations will be delivered to support your move toward certification and small-batch production. Questions: ========== Which microcontroller and BLE stack are you using (Nordic, ESP32, STM32, etc.)? Do you already have defined test cases or should we design the full test plan? Any specific battery-life targets or constraints we must validate? Is OTA already partially implemented or from scratch validation required? Best Regards, Srashtasoft Team

I have a wearable-tech prototype that is already built around a dedicated microcontroller, and I now need a skilled IoT engineer to pull the hardware and firmware pieces together and prove they work under real-world conditions. The core electronics are stable; what I’m missing is the systematic integration, end-to-end functional testing, and clear documentation that will let us move toward small-batch production without surprises. Your mission is to connect the microcontroller firmware, power management, and communication stack with the companion mobile app and backend that my software team is finalizing. I’ll supply full schematics, current firmware source, and the test jigs we use in-house. I need you to: • Review the existing microcontroller code and hardware interface • Design and run integration tests (functional, stress, and regression) • Identify and fix any firmware–hardware mismatches or timing issues • Produce a concise test report with pass/fail results, logs, and recommendations Acceptance criteria: all advertised features (BLE pairing, sensor polling cadence, battery-life targets, and OTA update handshake) must pass the agreed test plan with reproducible results. If you’re comfortable flashing microcontrollers, capturing traces with logic analyzers, and automating test suites, I’d love to get this wrapped up quickly so we can head into certification.
