BlueR tools -- swiss army knife for GATT services and L2CAP sockets on Linux

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

The following command line tools are included.

• blemon: Scans for and monitors Bluetooth LE 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 LE L2CAP sockets.

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

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

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.
