Bluetooth Scanner Tag Finder for Android

Bluetooth Scanner Tag Finder is a utility application designed for Android devices to help users locate misplaced Bluetooth accessories quickly. It continuously scans for Bluetooth Low Energy (BLE) signals, identifying nearby devices and reporting their signal strength in decibels (RSSI). Key features include real-time scanning, a radar-style display for direction, and device filtering options, making it particularly useful for those who frequently misplace items like earbuds, smartwatches, or Bluetooth tags. The app operates without requiring prior pairing with devices, allowing for a broad search of any actively broadcasting Bluetooth device within range.

The application detects devices by listening for Bluetooth signals and does not support powered-off devices. Distance estimation is based on RSSI readings, which tend to be most accurate in open areas and can be affected by obstacles like walls or furniture. While resource consumption is low, enabling practical searches without significant battery drain, the app's effectiveness may vary depending on the environment. Overall, it serves as a practical tool for indoor recovery of Bluetooth accessories.
