    Hi,

    I want to use it to scan nearby mobile phones but i am not sure if i can
    make it with LTE_fdd_dl_scan.

    -Can i capture broadcast packets with LTE_fdd_dl_scan?
    -Do you have a more detailed documentation that explain how the
    LTE_fdd_dl_scan works?

    I would like to use SDRplay with the scanner application. I see that
    gr-osmoSDR is supported but i see in the code that only support rtl-sdr,
    hackrf, USRP B2X0 and bladeRF.

    -Do someone try the LTE_fdd_dl_scan with SDRplay RP1?

    Thanks for this extraordinary project!

    Good question ... LTE_fdd_dl_scan is able to decode and present information of MIB and SIB1 and SIB2 but dont know if you can enable a feature to capture those packets as, for example .pcap packet so later on you can check it on wireshark ... then I started to look for something like "enable_pcap" on the source files of LTE_fdd_dl_scan:

    root@kali:~/Documents/openlte/openlte_v00-20-04/LTE_fdd_dl_scan/src# ls -l
    blurblurblurblurblurblurblurblurblurblur LTE_fdd_dl_scan_flowgraph.cc
    blurblurblurblurblurblurblurblurblurblur LTE_fdd_dl_scan_interface.cc
    blurblurblurblurblurblurblurblurblurblur LTE_fdd_dl_scan_main.cc
    blurblurblurblurblurblurblurblurblurblur LTE_fdd_dl_scan_state_machine.cc

    And on LTE_fdd_dl_scan_interface.cc i found a line containing:

    current_dl_earfcn = dl_earfcn_list[dl_earfcn_list_idx];
    repeat            = true;
    enable_pcap       = false;      <<<<<<<< HERE!!!
    shutdown          = false;
    

    So if I change it to "TRUE" and compile it again ... that might work to start capture those packets??? can somebody confirm this? Thanks
