  • https://en.wikipedia.org/wiki/Bluetooth - a wireless technology standard for exchanging data over short distances (using short-wavelength UHF radio waves in the ISM band from 2.400 to 2.485 GHz) from fixed and mobile devices, and building personal area networks (PANs). Invented by Dutch electrical engineer Jaap Haartsen, working for telecom vendor Ericsson in 1994, it was originally conceived as a wireless alternative to RS-232 data cables.

Standards



  • https://en.wikipedia.org/wiki/Bluetooth_Low_Energy - Bluetooth LE, colloquially BLE, formerly marketed as Bluetooth Smart) is a wireless personal area network technology designed and marketed by the Bluetooth Special Interest Group (Bluetooth SIG) aimed at novel applications in the healthcare, fitness, beacons, security, and home entertainment industries. Compared to Classic Bluetooth, Bluetooth Low Energy is intended to provide considerably reduced power consumption and cost while maintaining a similar communication range.Mobile operating systems including iOS, Android, Windows Phone and BlackBerry, as well as macOS, Linux, Windows 8 and Windows 10, natively support Bluetooth Low Energy. The Bluetooth SIG predicts that by 2018 more than 90% of Bluetooth-enabled smartphones will support Bluetooth Low Energy.

Libraries

  • https://github.com/OpenBluetoothToolbox/SimpleBLE - aims to provide fully cross-platform BLE libraries and bindings for Python, Rust and C++, designed for simplicity and ease of use with a licencing scheme chosen to be friendly towards commercial use. All specific operating system quirks are handled internally to provide a consistent behavior across all platforms. The libraries also provide first-class support for vendorization of all third-party dependencies, allowing for easy integration into existing projects.

Linux



  • Bluez - provides Linux support for the core Bluetooth layers and protocols. It is flexible, efficient and uses a modular implementation.


  • https://linux.die.net/man/1/hcitool - used to configure Bluetooth connections and send some special command to Bluetooth devices. If no command is given, or if the option -h is used, hcitool prints some usage information and exits.



  • https://github.com/darkhz/bluetuith - a TUI-based bluetooth connection manager, which can interact with bluetooth adapters and devices. It aims to be a replacement to most bluetooth managers, like blueman.



Scanning

  • l2ping - Send L2CAP echo request and receive answer


  • https://github.com/greatscottgadgets/ubertooth - an open source wireless development platform suitable for Bluetooth experimentation. Ubertooth ships with a capable BLE (Bluetooth Smart) sniffer and can sniff some data from Basic Rate (BR) Bluetooth Classic connections.


  • https://github.com/pwnieexpress/blue_hydra - a Bluetooth device discovery service built on top of the bluez library. BlueHydra makes use of ubertooth where available and attempts to track both classic and low energy (LE) bluetooth devices over time.



Beacons

  • https://en.wikipedia.org/wiki/Bluetooth_low_energy_beacon - hardware transmitters - a class of Bluetooth low energy (LE) devices that broadcast their identifier to nearby portable electronic devices. The technology enables smartphones, tablets and other devices to perform actions when in close proximity to a beacon. Bluetooth beacons use Bluetooth low energy proximity sensing to transmit a universally unique identifier picked up by a compatible app or operating system. The identifier and several bytes sent with it can be used to determine the device's physical location, track customers, or trigger a location-based action on the device such as a check-in on social media or a push notification.
