I am building a Cordova-based fitness app that will run on an H96 Android TV stick. The stick will use a standard ANT+ USB dongle, so the plugin has to speak to Google’s USB Host layer and the ANT+ API, then expose clean JavaScript calls inside Cordova. Core requirements • Heart-rate data retrieval in real time. • Reliable device discovery, pairing, and reconnection handling for multiple sensors. • Tested compatibility with Wahoo, Polar, and Coospo chest straps (other ANT+ HR straps should still work if they follow the spec). • An async method that lets me push the collected sessions to an external REST endpoint (JSON payload, basic auth token). • Build targets: Android only for now; everything must compile with the current Cordova Android platform and Gradle tool-chain. Deliverables 1. Full Cordova plugin (Java/Kotlin native layer + JS bridge). 2. Demo project showing live heart-rate streaming on screen. 3. Setup notes so I can reproduce the build on my machine. 4. Short API guide that explains connection flow, event callbacks, and the sync function. 5. At least one recorded test session per supported strap proving stable data capture over 15 minutes. Acceptance will be based on the demo running flawlessly on my H96 stick with the ANT+ dongle, maintaining the connection throughout, and uploading a test JSON file to a staging server I will provide.

Hi, It's good to talk with you. I can build the Android-only Cordova plugin for ANT+ heart-rate sensors on your H96 Android TV stick. I would create the native Java/Kotlin layer using Android USB Host and ANT+ APIs, then expose clean JavaScript methods inside Cordova for discovery, pairing, live heart-rate streaming, reconnection, and session sync to your REST endpoint. I can also provide a demo Cordova app showing real-time HR data on screen, setup/build notes, and a short API guide for callbacks, connection flow, and JSON upload. I understand the key point here is stable long-running capture, not just a basic connection, so I would focus on reconnection handling and testing with ANT+ chest straps. I can start by reviewing your current Cordova setup, Android platform version, and the ANT+ dongle model. Regards, Delcimario Alves

Hi, You’re not just building a plugin , you need a stable bridge between ANT+ hardware, Android USB Host, and Cordova’s JS layer that won’t drop sessions mid-run. That’s exactly the kind of integration where connection state, reconnection logic, and clean event flow matter more than the code volume. I’ve built Android-native integrations and Cordova bridges before, and I can structure this plugin with a reliable Java/Kotlin layer, JavaScript API, and a demo app that proves live heart-rate streaming on the H96 stick. I’ll also include the sync method for REST uploads with JSON + basic auth, plus setup notes and an API guide so you can reproduce the build confidently. I’ve shared an initial estimate based on your description, and once we go over a few technical or functional details, I’ll confirm the exact cost and delivery schedule. If helpful, I can map the device discovery flow first, then implement sensor pairing, reconnect handling, and the 15-minute test sessions for Wahoo, Polar, and Coospo. Which ANT+ Android library or vendor SDK do you want me to build around, and do you already have the staging endpoint format? Thanks, Asad

Hi I am a software engineer with over 12 years of experience building Android native integrations, Cordova plugins, USB Host communication, Bluetooth/ANT style sensor flows, and production fitness/IoT apps. I can build the Android-only Cordova plugin with a clean JS API, native Java/Kotlin layer for ANT+ heart-rate discovery, pairing, streaming, reconnect handling, and a small demo app that shows live HR data and uploads session JSON to your REST endpoint with basic auth. My approach would be to keep the Cordova side simple and stable: event callbacks for discovery/status/heart-rate updates, promise-based methods for connect/disconnect/sync, and clear setup/API notes so you can reproduce the Gradle build on your H96 stick. I will also make the reconnect logic practical for multiple straps, since that is usually where sensor apps fail in real use. A few details I would confirm first are the exact Cordova Android version, ANT+ dongle model, whether you can provide remote access/video validation on the H96 stick, and the staging endpoint format. Please contact me to discuss details.

Hi, I specialize in mobile app development with expertise in Java and Kotlin. Your project involves creating a Cordova plugin for Android that captures real-time heart rate data over ANT+ USB dongle on an H96 TV stick. The best solution is to develop a native plugin interfacing with Google’s USB Host APIs and ANT+ services to ensure reliable sensor pairing and data streaming. I will implement the plugin's native side in Java/Kotlin, and bridge it to JavaScript for Cordova integration. This includes real-time heart rate streaming, multi-sensor management, and async data upload using REST and basic auth. I can communicate in real time in your time zone and provide a demo within 12 hours of starting. Q1: Do you have specific ANT+ API version requirements? Q2: What are the precise JSON payload fields for the session upload? Q3: Should the plugin support background data syncing outside the app runtime? Best regards, Everett

8+ years Cordova + Android native plugins. Built 3 fitness/BLE/ANT+ integrations for Android TV. USB Host + ANT+ SDK experience. Existing `cordova-plugin-antplus` exists but outdated (last update 8+ years ago, 0.8.1) . Needs modern rewrite for current Cordova Android + Gradle. Your H96 stick + USB dongle setup works via Android USB Host API + ANT+ SDK . Main challenge: USB Host activation on Android TV (known Waydroid/Android TV USB issues) . My approach: - Native layer: Kotlin + Android ANT+ SDK plugins (HeartRate profile) - USB Host: Request USB permission, detect ANT stick, initialize ANT service - JS bridge: Event callbacks for HR data, device pairing, reconnect handling - Data sync: Async REST POST with auth token, JSON payload What I need to confirm before starting: 1. Does your H96 stick run Android 10+ (USB Host API varies)? 2. Do you have ANT USB stick model (Garmin/Suunto/other)? 3. Existing Cordova version + Android platform version Timeline: 3-4 weeks including testing on all 3 strap types (Wahoo, Polar, Coospo). Fabien
