Hello there, I can develop an Android Coffee Roaster HMI that precisely controls roasting parameters and streams real-time telemetry—temperature, roast time, and fan speed—with smooth, low-latency visuals and safe control limits. The app will support multiple roasting profiles (create, edit, clone, import/export), live curve tracking, and roast logging. I’ll implement robust device comms (BLE/Wi-Fi/serial as provided), a resilient data pipeline (coroutines/Flows), and a clean UI with Jetpack Compose. Expect profile-based setpoints, optional PID hooks, alerts on deviation, and an offline-first architecture with secure persistence. Questions: – What is the communication layer to the roaster (BLE GATT spec, Wi-Fi TCP/UDP, or USB-serial), and do you have a protocol document? – Should closed-loop control (PID) run on the app or on the roaster’s controller, with the app sending setpoints only I am a TOP Rated Freelancer, and you can check my past work and reviews here as well: https://www.freelancer.com/u/kamran2012 Looking forward to potentially working together on this project. Thanks and Best regards, Kamran

Hi, I'm an experienced Android developer with a background in real-time control interfaces and have previously built HMI-style apps for hardware control and data visualization. One key challenge in a coffee roasting HMI is managing accurate, real-time display and adjustment of parameters like temperature, roast time, and fan speed—I’ve handled this using Bluetooth/Wi-Fi communication with serial parsing and custom threads for responsive UI updates. I can implement multi-profile roasting logic, allowing users to create, save, and load presets with smooth transitions and fail-safes. My previous work includes IoT apps with control system integration and industrial sensor monitoring, making this a strong fit. Thanks, Hercules

@kreativesol

Hey there, Good day! ✅ Could you clarify how the Coffee Roaster will communicate with the app—Bluetooth, Wi-Fi, or a wired connection? Also, do you already have an API or protocol to interface with the roaster hardware? Here are a few suggestions for your app: * Implement real-time graphs for temperature and fan speed to help users monitor roasting progress visually. * Allow users to save, load, and modify multiple roasting profiles for consistency. * Include alert notifications for thresholds (e.g., max temperature or time) to prevent mistakes during roasting. I have extensive experience developing Android apps with real-time data display and control interfaces, including IoT and hardware integration. Samples of similar HMI projects can be provided upon request. Thanks and Regards, Abdul Basit Kreative Solutions
