Hi Ben,

I have released openLTE V00.08.03 (http://sourceforge.net/projects/openlte/)
with support for HackRF and RTL-SDR via GrOsmoSDR. Using this release, I
have been able to successfully decode broadcast information (MIB and SIBs)
from LTE networks.

Thanks for the update & congratulations!

I was also wondering if there is a good way to determine which type of
hardware is connected?

Ideally you enumerate through available devices and select one to work with (example attached). Then you pass it's device string to the source/sink and continue from there as usual. You can check for something like dev.count("rtl") || dev.count("rtl_tcp") and dev.count("hackrf") to distinguish between devices. In our applications we also provide a command line switch like

        parser.add_option("-a", "--args", type="string", default="",
                          help="Device args, [default=%default]")

to select a specific device via CLI and to be able to change it's default parameters: -a "hackrf,buffers=128".


Best regards,
Dimitri
