Project Description We are looking for an experienced Android developer to build an Android application that connects to a Smart Weight Scale via Bluetooth Low Energy (BLE) using the official AILink (Pingwang) SDK. The app must: Read accurate real-time weight from the scale Display nutrition information (calories, protein, carbs, fat, fiber, etc.) based on food selection and measured weight This is a hardware + SDK-driven project, not a generic Android app. Core Requirements 1. BLE & SDK Integration > Android BLE scanning and connection > Must use AILink SDK & Parsing Library only > Follow Chinese AILink SDK documentation strictly > No custom BLE decoding or reverse engineering 2. Weight Reading > Detect the scale via BLE > Read and display accurate weight values > Must work on real Android devices, not emulator only 3. Nutrition Feature (After Weight) > Scale provides only weight (grams) > User selects a food item > App calculates: Calories Protein Carbohydrates Fat Fiber > Nutrition is calculated using reference data (per 100g) > Nutrition data is NOT from BLE 4. UI > Simple and clean UI is enough > Show: > Bluetooth status > Weight > Selected food > Nutrition values ** What We Will Provide AILink SDK documentation (Chinese team PDF) SDK dependencies and versions Smart scale hardware for testing Clear requirement document (PDF)

What stood out immediately is that this is a hardware + vendor-SDK driven Android app, not a generic BLE experiment. Using the official AILink (Pingwang) SDK only, following their documentation strictly, and validating everything on real devices with real hardware is exactly the right approach — and one I’m comfortable with. I’ve worked on BLE-based Android apps tied to proprietary hardware SDKs, where accuracy, lifecycle handling, and strict compliance with vendor libraries matter more than UI polish. How I’d approach this project BLE & AILink integration * Implement BLE scanning, connection, and lifecycle using the AILink SDK and parsing library only * Follow the Chinese SDK documentation precisely (no custom decoding, no shortcuts) * Test exclusively on real Android devices with the provided scale hardware Weight reading * Detect the smart scale reliably * Read and display real-time, stable weight values from the SDK * Handle connection states and edge cases cleanly Nutrition calculation (app-side logic) * User selects food item * Use reference nutrition data (per 100g) stored locally or via simple config * Calculate calories, protein, carbs, fat, and fiber based on measured grams * Keep BLE logic and nutrition logic cleanly separated Once you share the SDK docs and hardware, I can confirm timeline and milestones quickly. This is exactly the kind of SDK-driven Android integration I’m used to delivering. Best regards, Jenifer

Drawing from my expertise as an Android App Developer, I believe I am the ideal candidate for your BLE Smart Scale project. Not only am I well-versed in working with the AILink SDK and BLE integration, but my experience also extends to building solutions that heavily interact with hardware. Crucially, my work adheres rigorously to strict Chinese AILink SDK guidelines and does not employ any custom BLE decoding or reverse engineering, offering heightened security and reliability. Beyond the core functionality of connecting with the scale and capturing accurate weight readings on real Android devices, your additional requirement of nutritional information is where my AI skills come into play. By utilizing reference data, I can help calculate the calories, protein, carbohydrates, fat, fiber, etc., even if they aren't sourced from the BLE. Incorporating such insightful features has always been my forte. Lastly, on a pragmatic note, even as a React Native and Flutter expert, my background with Java for Android will be invaluable in this project. With meticulous attention to detail and a passion for creating seamless user-experiences steeped in modern technologies like AI and automation, I'm confident in delivering beyond your expectations. Let's work together towards an app that's efficient and intelligent while being remarkably receptive in design!

Hello, I’m an experienced Android developer with solid hands-on experience in BLE-based hardware integrations and SDK-driven apps. I can build this application exactly as specified using the official AILink (Pingwang) SDK and parsing library only, strictly following the Chinese SDK documentation—no custom BLE decoding or reverse engineering. I’ll handle BLE scanning, connection, and stable communication with the smart weight scale on real Android devices. The app will accurately read and display real-time weight values provided by the scale via the AILink callbacks and data models. After weight measurement, I’ll implement the nutrition calculation layer as described: the user selects a food item, and the app calculates calories, protein, carbohydrates, fat, and fiber using reference values per 100g. Nutrition data will be handled entirely in-app and is not sourced from BLE. The UI will be simple and clean, clearly showing Bluetooth connection status, current weight, selected food, and calculated nutrition values. Code will be structured, maintainable, and compatible with your provided SDK versions. Testing will be done on physical Android devices using the supplied smart scale hardware, with proper handling for reconnects, errors, and edge cases. Delivery includes full source code and brief documentation explaining SDK setup, key integration points, and where calculations are performed. Best regards, Arindam Roy

Hi There, I’ve gone through your requirement for the Android application integrating a Smart Weight Scale using the AILink (Pingwang) BLE SDK, and this is well within my expertise. I have strong experience working on hardware-integrated Android apps, BLE communication, and SDK-driven implementations where strict protocol compliance is required. What I will deliver for this project: - Proper BLE scanning, connection, and data handling using the official AILink SDK & parsing library only (no custom decoding) - Accurate real-time weight reading tested on real Android devices with provided scale hardware - Nutrition calculation module based on per-100g reference data after food selection (calories, protein, carbs, fat, fiber) - Simple, stable UI showing Bluetooth status, weight, selected food, and nutrition breakdown A couple of quick questions: Do you already have a predefined nutrition reference dataset, or should I integrate a standard food database? Is the target Android version range fixed (e.g., Android 8–14), or should it support the latest API levels only? I’m ready to start immediately and can work closely with your team to ensure accurate BLE readings and smooth SDK integration. Best Regards, Shiv
