[srslte-users] srsUE not joining any cell

[Kenny Barlee]

Hi

I'm having trouble attaching a USRP B210 with srsUE to an amarisoft 
eNB/ePC. Other commercial UEs I have to hand can connect.

I am using the latest build, and the default ue config (except the usim 
details). With dl_earfcn=3400 (band 7), or any other earfcn/ override 
uldl frequencies for other bands, I get the following error:

    sudo srsue

....etc

Has anyone come across this before?

Thanks
