I have an RFID reader that must talk directly to an Android device over Bluetooth, but the manufacturer never released an SDK. I need someone who can reverse-engineer or otherwise interpret the reader’s raw Bluetooth packets, pull out the numeric data stored on each tag, and feed that information into a brand-new Android app built specifically for this purpose. Here’s how I picture the workflow: • The app scans for and pairs with the reader via standard Bluetooth settings. • Once connected, it listens for the reader’s data stream, decodes each frame, and extracts only the numeric payload from every tag scan. • The app then displays the tag number on screen in real-time (simple list view is fine for now) and stores it locally for later export. ...
