[srsran-users] How to run srsUE standalone to connect to commercial eNB: "Failed to initialize USIM"

[Sabyrzhan Tasbolatov]

Hello,

I don't have experience with srsRAN, but I dont need srsenb and srsEPC,
as I need to capture Uplink LTE waveform IQ samples (i guess i will
figure out it later -- should be debug log level ?)

So my understanding is that I need to use "srsue" application.
I've built srsRAN from current master branch:

$ git log -1

    Merge branch 'next' into agpl_next

    # Conflicts:
    #       cmake/modules/FindPolarssl.cmake

I have bladeRF with 0.11.0 FPGA firmware.
Also have smart-card reader where I've inserted my USIM card.

Here ue.conf sections I've modified:

[rf]
device_name = soapy
device_args = driver=bladerf

[rat.eutra]
# this is EARFCN of the local eNB
dl_earfcn = 1652

[usim]
mode = pcsc
#algo = milenage
#opc  =
#k    =
#imsi =
#imei =
reader =
pin = 0000


pcsc_scan and pcsc_usim_test works fine. It can read USIM via PC/SC interface.

Here the output: (I've tried to run it with sudo copying user's
ue.conf to root directory.

$ ./srsue --usim.mode=pcsc
