Bluetooth Radar is a tool for analyzing Bluetooth (BLE) environments. Scans the BLE ether in the background, notifying you if the device you are looking for is near you or if some unknown device has been following you for too long. Able to distinguish manufacturers, explore Apple Airdrop packages, and match them with known contacts. Build a device movement map based on the scanned BLE ether around you. Bluetooth Radar allows you to create flexible filters for the radar with logical operators. Able to distinguish manufacturers, explore Apple Airdrop packages, and match them with known contacts. Build a device movement map based on the scanned BLE ether around you. For example, you can search for devices that you have seen in a certain period of time, receive a notification if your friend's headphones suddenly appear near you, or find your own device that you have lost. Bluetooth Radar does not share your personal data or geolocation, all work is offline. This is an open-source project.
