IMSI successfully delivered a Bluetooth-enabled desktop application for logistics, built using the Python Flask web framework with Socket.IO to enable real-time data updates.

The application is deployed on Windows tablets and is designed to guide forklift drivers in moving pallets of items to and from storage through an interactive user interface.

It integrates seamlessly with the existing logistics server application via Bluetooth, allowing message exchange and database synchronization between the tablet application and central logistics system.

Following the successful delivery of a full-stack logistics control system last year, a manufacturer approached IMSI to develop a tablet-based application that could integrate with their existing logistics system and guide forklift drivers in moving items to and from storage areas.

To meet this challenge, IMSI developed a Bluetooth-enabled desktop application using the Python Flask web framework with Socket.IO to enable real-time data updates.

Three custom APIs were developed to integrate the desktop application with the server application over Bluetooth. These APIs interact asynchronously to handle both scheduled and triggered data exchanges between the two applications.

Database synchronization is carefully managed: the server application is the primary source of truth, and updates are propagated to the desktop application. If the desktop application requests a change, a Bluetooth message is sent to the server, where the API processes the request, updates the database, and returns the updated status to the desktop application to update its local database.

Any changes made by the server are sent as status messages to the desktop application to ensure local database consistency. The application also provides automatic synchronization in case the connection is lost, ensuring continuous and reliable operation.

Services Used On This Project

Warehouse Management System

Warehouse Management System

A warehouse management system (WMS) coordinates the flow of goods, data, and operations inside a warehouse so inventory moves with accuracy, speed, and traceability. It acts as the operational backbone for modern supply chains, connecting people, equipment, and digital systems into one coordinated environment.

Core functions

  • Inventory visibility — Tracks every item’s location, quantity, and movement in real time, reducing stockouts and overstocking.
  • Receiving and put‑away — Guides operators through optimized storage locations to minimize travel time and improve space utilization.
  • Picking and packing — Supports batch, wave, zone, and automated picking strategies to increase throughput and reduce errors.
  • Order management — Prioritizes and sequences orders based on deadlines, carrier schedules, and resource availability.
  • Dispatch and shipping — Ensures correct labeling, documentation, and carrier integration for smooth outbound logistics.
  • Cycle counting and audits — Maintains inventory accuracy without shutting down operations.
