Hello, I will deliver a focused STM32 firmware test package in 14 days for your autonomous robot project. The plan is to provide a modular STM32CubeIDE skeleton, UART stacks for GNSS and Bluetooth, encoder handling (real or simulated), a control loop, and an ASCII command protocol, with a simulation mode that clearly shows state changes and logging. Deliverables include a 6–10 page PDF detailing the architecture and data flow, a portable STM32CubeIDE project (ZIP or repo), and a README with build and test steps. I will keep scope fixed, meet the deadline, and deliver clean, readable code with proper documentation. Important technical questions: Confirm target STM32 family (F4 / F7 / G4) and toolchain preferences. What are the UART baud rates and any framing/parity for GNSS, Bluetooth, and command channels? How should the simulation mode log data, what fields to include, and which test vectors should be used? What are the acceptance criteria for GNSS NMEA parsing and encoder handling in simulation, and any edge cases to cover? Any preferred documentation style or template for the PDF and README? Which STM32 family (F4, F7, or G4) do you want me to target for this 14‑day test, and are there any constraints on toolchain or build environment? Best regards,

Hi there, I’ve carefully reviewed the details of your STM32 Firmware Consultant – 14-Day Technical Test, and I confirm that I can deliver the complete task within 14 calendar days for the fixed fee of USD 300, following your milestone and documentation requirements exactly. I’m an experienced embedded systems engineer with nearly five years of work in STM32-based development, including real-time control, sensor integration, and communication protocols. I’ve completed multiple modular firmware projects using STM32CubeIDE, both with FreeRTOS and bare-metal architectures, and I’m comfortable producing clean, well-documented code with clear data flow and state-machine diagrams. For this task, I’ll base the work on the STM32F4 family, ensuring full compatibility with your test requirements: UART communication (GNSS + Bluetooth), encoder handling (simulated or real), ASCII command protocol, and simulation mode with clear logging and state transitions. If this aligns with your expectations, just send me a message to confirm the start — I can begin immediately. Best regards, Samuel Tshibangu
