Bonrix Desktop Utility: Connect Bluetooth Weigh Scales to Web Applications via WebSocket
Is your web-based POS or ERP system struggling to integrate Bluetooth weigh scales? You’re not alone. In today’s cloud-driven retail world, browsers block direct Bluetooth serial access—making real-time weight-based billing seem impossible.

Bonrix Utility: Connect USB-Serial (RS232) Weighing Scales to Web-Based POS and ERP Using WebSocket
In the shift toward cloud-based, browser-driven retail systems, a critical gap remains: web apps cannot natively communicate with legacy USB-Serial (RS232) weighing scales—forcing a trade-off between modern software and accurate, automated billing.
💡 Not anymore.
Introducing the Bonrix Desktop Utility—a lightweight Windows app that bridges RS232 scales to any web application via real-time WebSocket streaming.
🔗 How It Works: Connect your scale (via USB-Serial adapter) → Utility reads serial data → Streams to ws://127.0.0.1:8053 → Your web POS receives live weight—no manual entry, no polling.
⚙️ Transforms Your Workflow:
• Legacy-to-Web Bridge – Bypass browser restrictions; integrate without rewriting your system.
• Real-Time Billing – Instant weight sync eliminates typos and speeds checkouts.
• Automated Workflows – Auto-fill items, compute pricing, update inventory.
• Digital Checkout Ready – Trigger UPI QR or other payment flows post-weighing.
✔ Designed For: Supermarkets, fresh produce & meat markets, logistics hubs, scrap traders, and any web-ERP user needing hardware integration.
🛠️ Simple 5-Step Setup:
1. Connect RS232 scale via USB-Serial adapter
2. Launch Bonrix Utility → Select COM Port & Baud Rate
3. Start local WebSocket server
4. Point your web app to the WebSocket URL
