A powerful Bluetooth scanner that supports scanning:

• BR devices
• LE devices
• LMP
• GATT
• SDP
• Vulnerabilities (demo)

Requirements

sudo apt install libglib2.0-dev libbluetooth-dev

# This tool is based on BlueZ, the official Linux Bluetooth stack.
# If you want to try the vulnerabilities scanning, see requirements in
# README.md of https://github.com/ojasookert/CVE-2017-0785
