[srslte-users] SRS UE connecting to commercial network

[Saimanoj Katta]

Hi,

I will be using the srsLTE UE code with USRP X310 to connect to a
commercial enB and EPC.
When I run the command srsue   --rf.dl_earfcn  3350 to detect the eNB, I
get the following error(pasted below).  What are the values rv_idx and
cb_idx. How can I rectify them?

Furthermore, what parameters need to be changed in UE code so that eNB can
detect it?
>From my understanding, IMSI, K, OPC values could be changed in the
configuration file. I cannot understand how to change other parameters(if
required!

Reading configuration file /home/ubuntu/.config/srslte/ue.conf...

Built in Release mode using commit 5343b33f on branch master.
