WHAT WE NEED Licensed Windows diagnostic software stays on the PC. On the same Wi‑Fi, a phone app drives it natively (no screen mirroring / no video stream of the desktop). Menus, order, icons, and labels must match the PC app (schema/IDs + mapping you build). Live data (DTCs, live values, session state, etc.) flows PC ↔ VCI path through your engine — not placeholder UI. Exact signals vs PC screen are nailed in a short discovery phase.

Hi, this is a well-defined system, but the real challenge is reliably bridging a Windows diagnostic app with a mobile UI while keeping live data sync stable and secure. I’ve worked on similar integrations and can deliver a production-ready setup. I’d build a .NET (C#) Windows engine using UI Automation (with fallback strategies if needed) to interact with the desktop app, exposing a structured WebSocket API over local Wi-Fi. This won’t mirror UI—it will map to a proper data model for DTCs, live values, and session state. Main risk is UIA coverage, which I’ll validate in a short discovery phase. Mobile will be built in Expo (React Native) with a responsive UI mapped to your schema. Pairing via QR, language packs cached with versioning, and local-only communication with the engine. Backend will handle licensing (Google Play Billing + Apple IAP), receipt validation, pairing, and admin controls with audit logs. Engine remains free, but live control is license-locked. Cars/Trucks modes will use configurable exe paths + args. VCI test flow will be mapped via engine automation. I confirm full source delivery + IP assignment. Discovery deliverable: feasibility report (UIA, performance, VCI path, pack delivery choice, gaps). Let’s start with discovery and validate feasibility quickly. Feel free to open a chat and let's discuss. ~ Rajesh

DRIVE A DESKTOP-ONLY DIAGNOSTIC TOOL FROM MOBILE—NATIVELY, FAST, AND LICENSED RIGHT. Architecture & Risks PC .NET (C#) engine runs always-on, automates the Windows app via UIA + fallback hooks (where UIA gaps exist), and exposes a typed data model over secure WebSocket (LAN only). Mobile (Expo/React Native) consumes this model to render identical menus (ID→UI mapping) and real live data (DTCs, streams). Sync is event-driven (diff/patch + heartbeat) to avoid churn. Biggest risks: partial UIA coverage, timing/race conditions, and VCI access paths—handled via discovery probes, control map registry, and retry/state reconciliation. Discovery Deliverable (1–2 weeks) Written feasibility: UIA coverage map, perf limits, Cars/Trucks attach via configurable exe path + args, exact VCI test flow mapping, pack delivery choice (QR→HTTPS URL preferred for large packs + retries), and gaps vs PC app with mitigations. Mobile (Expo) + iOS Android first (Expo). iOS delivered as Phase 2 (2–3 weeks) with same codebase (Expo + native modules if needed). Includes Apple IAP, Sign in with Apple, parity with Google Play Billing. If approved, can run parallel after discovery. Licensing/Backend/Admin Node.js service: receipt validation (Google/Apple), pairing, short-lived tokens, revoke/suspend, promo codes, audit logs. Engine unlocks live control only after pairing + license check.

Hey, I will build the C# WebSocket bridge engine that automates the desktop diagnostic app via UIA, the Expo (React Native) mobile client for Android, and the backend for licensing — Google Play Billing, Apple IAP with server receipt validation, and a web admin panel for suspend/revoke/audit logs. For live sync, the engine will maintain a structured data model — not scraped menu text — mapping UIA AutomationIDs to a schema that pushes DTCs, live values, and session state over WebSocket on the local network. The discovery document will cover UIA element coverage for both Cars and Trucks launch modes, VCI test path automation, and the QR-based language pack delivery approach. iOS will follow as a phased milestone after Android sign-off, with Apple IAP and Sign in with Apple scoped in from day one. Looking forward to talking through the details. Kamran

Hi there, I have read your project requirement and you need a Windows-based diagnostic engine (C#) connected to an Expo (React Native) Android app (and iOS in scope) that communicates over local Wi-Fi, mirrors the desktop app’s structure, streams real diagnostic data, and includes licensing, admin control, and store-compliant billing. We can design a robust architecture with a .NET engine (UI Automation + WebSocket layer), Expo-based mobile apps, and a secure backend for licensing, IAP validation, and admin control, ensuring real-time sync, stable performance, and compliance with Play Store / App Store policies. A few quick questions: ================== Does the desktop app expose any internal API/hooks, or should we rely fully on UI Automation (UIA)? What is the expected data frequency for live streams (to design WebSocket throughput and buffering)? Should engine ↔ mobile communication be fully local-only or include fallback via cloud (for diagnostics/support)? Do you prefer iOS delivery in the same phase or as a milestone after Android (with Apple IAP setup)? Best Regards, Srashtasoft Team

Based on the requirements, I propose a 3-part architecture: a C# Windows engine using UI Automation for controlling the licensed diagnostic software and WebSocket for real-time data streaming, an Expo React Native app for Android (plus iOS as a follow-on milestone) that mirrors the PC app’s UI from a mapped schema, and a backend admin service managing license validation, purchases (Google Play + Apple IAP), and audit logs. Biggest risk is UI Automation coverage on the diagnostic software menus and live data elements. I handle this by an early discovery phase with detailed feasibility testing of UIA versus embedded web or other hooks, plus testing engine performance for live sync without lag or data loss. I have delivered a similar diagnostic tool controller for a vehicle fleet management company—built a local bridge engine paired to mobile apps with real-time telemetry and strict licensing controls. Full source and IP assignment is fine. Discovery will include a clear written report on UIA coverage, gap mapping, pack delivery via QR over Wi-Fi versus HTTPS, and approach for the two desktop modes (Cars/Trucks). Team split: .NET engine (20h/wk), Expo mobile (25h/wk), backend/admin (15h/wk). I suggest iOS after Android launch with Apple IAP/sign-in included in the follow-on scope and assumptions documented. Ready to start the discovery phase and deliver a feasibility report within agreed timelines.

Hello, I will map the windows diagnostic app into a structured id based system so every menu, icon, and function can be mirrored exactly on mobile without screen streaming, then i will create a c sharp windows engine that runs alongside the desktop software and uses websocket communication to send live diagnostic data like dtc codes, sensor values, and session state to the phone while also handling limited ui automation where needed, after that i will set up a node js backend for licensing, secure pairing, and google play and apple purchase validation so only authorized devices can access live control, then i will develop the android app in expo react native to display the same interface structure and consume real time data from the pc engine over local wifi, including qr based pairing and language pack syncing, Let's have a detailed discussion, as it will help me give you a complete plan, including a timeline and estimated budget. I will share my portfolio in chat I look forward to hear from you. Thanks Best Regards, Mughira
