Interesting project, Your Python script handling decryption, parsing, and hardware communication is a solid foundation. I will port that logic into a Flutter app with a clean, tab-based interface that runs natively on both Android and iOS, covering USB serial and socket communication with automatic fallback between the two transports. The piece that matters most here is preserving your existing packet structure and timing during the refactor. I will keep the encryption layer identical to your current script and build the serial I/O layer so it handles connection drops and reconnects gracefully, which is where most diagnostic apps break down in real use. Questions: 1) Which encryption library or method does your Python script use (AES, custom XOR, something else)? Send me a message and we can go over the details. Best regards, Kamran

@XanvraTECH

Hello, Thanks for sharing the details. Since your Python script already handles the core logic, the best approach would be to first review it and confirm the communication flow, packet structure, and encryption method before converting it into the mobile app. For this type of hardware app, I would recommend Flutter with native Android/iOS bridges where needed for USB serial, socket communication, permissions, and firmware update handling. We can start with a testable build first covering connection, data read/write, and real-time decoded values, then move into settings, firmware upload, UI polish, and store compliance. Best wishes, Warda Haider

@Hubready

Hello!, I am a Florida-based senior software engineer(frontend, backend, ecommerce, etc) and I read your project description carefully. I understand this is about turning your existing Python logic for decrypting, parsing, and responding into a reliable cross-platform diagnostic app with BLE and Arduino integration. I have about 15 years of experience with Python, mobile app development, encryption, BLE, React Native, Flutter, and hardware-connected systems, so this fits my background well. My approach would be: 1) review your current Python script and data flow, 2) map the app architecture, 3) build the BLE/device communication layer, 4) integrate the UI and diagnostic flow, 5) test on real devices and edge cases. Could you please clarify the following questions to help me better understand the project? 1) Should the Python script remain the core logic, or do you want it ported into the mobile app stack? 2) What exact Arduino/BLE device setup should the app support? 3) Do you already have the screen flow in mind, or should I propose it? I’ve built similar app and system integrations before, and I’m the kind of freelancer who pays close attention to details so the final result is solid, not patched together. If helpful, I can start by outlining the best technical path before development. -James

@abhishek060

Hi, The difficult part of your project isn't the UI—it's preserving the existing Python communication logic (USB serial, sockets, encryption, packet timing, and firmware updates) so the mobile app behaves exactly like your hardware expects. I understand you already have a working Python script for decrypting, parsing, and communicating with the device. My first step would be validating that same communication flow on Android/iOS before building the interface. Initial milestone: USB Serial connectivity Wi‑Fi/Cellular communication Encryption/decryption compatibility Live decoded data display After that, I'll build the diagnostics dashboard with real‑time monitoring, parameter editing, firmware updates, and proper Play Store/App Store compliance. A few quick questions: Which USB serial chipset/protocol is used (FTDI, CP210x, CH340, CDC, or custom)? Is the encryption custom or based on a standard algorithm? Can you share the Python script and a sample packet log? If you share the script, I can review it and provide a realistic timeline to the first testable APK/IPA. Looking forward to discussing the build. Regards Abhishek
