Blucat – netcat for Bluetooth

TCP/IP has tools such as nmap and netcat to explore devices and create socket connections. Bluetooth has sockets but doesn’t have the same tools. Blucat fills this need for the Bluetooth realm. Blucat can be thought of as a:

  • debugging tool for bluetooth applications
  • device exploration tool
  • a component in building other applications

Blucat is designed to run on many different platforms (including Raspberry Pi) by abstracting core logic from native code using the Bluecove library to interact with a variety of Bluetooth stacks. This talk will go over the objectives, designs, and current results of the project.
