srsUE cannot connect to srsENB #980

Open egortaran opened 2 years ago

egortaran commented 2 years ago

Issue Description

Hello everyone. I want, using documentation, to connect srsUE to srsENB and open5gs. Before that, I managed to connect COTS UE (One Plus 9). The phone managed to connect to the LTE network and was able to use the Internet. Now I want to connect srsUE, but I can't do it. UE detects PHY, but does not connect to the network

Interesting note. srsUE finds the cell, but then nothing happens. What should be done in this situation?
