BlueR tools — swiss army knife for GATT services, L2CAP and RFCOMM sockets on Linux

This crate provides tools for Bluetooth on Linux building on the functionality of the [BlueR crate]. A running [Bluetooth daemon (BlueZ)] is required.

The following command line tools are included:

• blumon: Scans for and monitors Bluetooth devices similar to top.

• gattcat: Swiss army knife for Bluetooth LE GATT services.

  • discovers Bluetooth LE devices and their services
  • pairing
  • resolves all well-known UUIDs and manufacturer ids
  • performs all possible operations on GATT services
  • connects (via notify and write) to a remote GATT service
  • serves (via notify and write) a local program over a GATT service
  • implements the [Nordic UART service (NUS)] as client and server

• l2cat: [netcat]-like for Bluetooth classic (BR/EDR) and LE L2CAP sockets.

  • connects to remote L2CAP PSMs
  • listens on local L2CAP PSMs and accepts connections
  • serves a local program on an L2CAP PSM
  • speed tests

• rfcat: [netcat]-like for Bluetooth RFCOMM sockets.

  • connects to remote RFCOMM channels
  • listens on local RFCOMM channels
  • serves a local program on an RFCOMM channel
  • resolve and publish SDP records
  • speed tests

Each tool supports the --help option for detailed usage information.

Installation

First, install D-Bus and Bluetooth libraries on your system. On Debian this can be achieved by running

sudo apt install libdbus-1-dev

Then, run the following command to install BlueR tools

cargo install bluer-tools

If you do not have Cargo on your system, you can use [rustup] for installing it.
