I was looking into Wi-Fi fuzzing (throwing wireless packets at a laptop with a Wi-Fi card) and found a tool that sped up the process of writing python scripts to inject packets. The tool is called Scapy - secdev.org/projects/scapy.

This would be a great tool to use when performing wireless auditing, since you could inject your own packets and learn how to find specific fields within a frame using wireshark.

I believe that LORCON & sharutils also need to be installed in order to construct your own packets to inject.

Would this be something that the BT devs would be interested in adding to the next release of BT? here is an article that discusses it further in case you want to explore this type of packet injection.
