Hi Jordan,

specan.py is library code, and wasn't really intended to be run directly. Yes, there is a __main__ in the module, but it was there more for testing. So you're not missing much. All it does is dump dBm vs. frequency readings, just like the C "ubertooth-specan" code.

That said, it should work for you. Try changing this line (around line 68) in specan.py:

    frame_source = ubertooth.specan(2402, 2480)

to:

    frame_source = ubertooth.specan(2.402e9, 2.480e9)

And see if that fixes your problem.

In short, I changed the arguments to the Ubertooth.specan() method, from being in MHz to being in Hz, but forgot to update that line of code... After I had specan_ui.py, I neglected the command line behavior of specan.py. Sorry about that.

I've committed this change to SVN -- now revision 244.
