DissPair is an open-source Bluetooth security and educational toolkit designed for exploring the low-level behavior of Bluetooth Classic (RFCOMM) and Bluetooth Low Energy (BLE GATT) in authorized lab environments. It goes beyond simple service discovery by actively probing devices to reveal their true hardware behavior. Key capabilities include RFCOMM channel enumeration, custom AT command and OBEX payload injection, flooding, and full BLE GATT service mapping and manipulation, making it a powerful resource for security researchers, developers, and hardware hobbyists auditing their own devices.
