Hi,
I know Bluetooth has been mentioned on the mailing list a few time, and
the
response was a bit varied, but I thought I’d mention that I’ve been
working
on it for this for the past few weeks.
I’m using the USRP to sniff packets on a single frequency, and it seems
to
work well, but the obvious problem is frequency hopping. I have two
questions:
-
What is the bandwidth of the RFX-2400 daughterboard, i.e. how many
Bluetooth channels (1MHz intervals) can I receive at any one time with
one
daughterboard? -
Or conversely, if I want to watch the hopping pattern using FFTs to
get the
order of the frequencies that it hops to, how many daughterboard will I
need
to use to view the full spectrum (80MHz)? -
If anyone is interested in playing with Bluetooth and the USRP and
would
like the code that I’ve written, let me know and I’ll send it. It’s in
a bit
of a horrible state and there’s no documentation as to how it works or
what
it does.
