I had some success running the scanner for a while using my BladeRF board however eventually the scanner crashes.. Here's the back trace..

Paul,

Thanks for reporting this issue. I'll take a look at the code and try to
provide a fix in V00.09.01.

FYI: I haven't officially supported blade rf, since I don't have one to
test on. If you haven't already, you should be able to increase the sample
rate that is being used to something like 15.36MHz in order to get SIB
decoding.

Thanks,
Ben
