UE doesn't connect

[GonCasMor]

Hello,

We have two LimeSDRs and we execute the srsLTE perfectly with a mobile phone. But, we have problems connecting the UE by doing "srsue". It seems that UE sometimes doesn't create the subnetwork (in fact, one time we got the subnetwork but we were unable to make pings). I don't know if it could be possible because the AGC is not supported? We let some part of the shell messages:

Thank you so much for your support. Gon_Cas_Mor

For the Lime, try to compile with LTE rates, i.e. cmake -DUSE_LTE_RATES=True ..
