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.
