Hello! Maybe it`s not correct to post in this section, so sorry.
I`m new to BT, and i`m interested in learning bluetooth security. But there is a little problem, today I can`t buy any of http://www.backtrack-linux.org/forum...r-choices.html these. How can I sniff bluetooth now at the baseband level? `Cause HCI it`s not enough. I`ve tried to find for csr bluecore4-ext dongles... no results. What do you use to sniff?

So that is the question - pleeease, help me to choose adapter. For USRP is rather expensive
