[srslte-users] Having troubles to connect srsUE with srsENB

[Mohammed Jabi]

Hi everyone,

I am totally new to srsLTE and any help would be appreciated. I am trying
to connect srsue with srsenb. I have followed all steps described in the
github page but ue is not able to detect enb.

I am using 2 BladeRFx40; one for ue and the other for enb. I am also
adopting the configuration provided without any changes. Both machines run
ubuntu 18.04.2 LTS and their CPUs are:
UE machine: Dual core Intel Core i7-4500U (-MT-MCP-) cache: 4096 KB
           clock speeds: max: 3000 MHz 1: 1151 MHz 2: 1101 MHz 3: 1078 MHz
           4: 1093 MHz
enB machine: Quad core Intel Core i7-3770 (-MT-MCP-) cache: 8192 KB
           clock speeds: max: 3900 MHz 1: 1774 MHz 2: 1922 MHz 3: 1797 MHz
           4: 1769 MHz 5: 1818 MHz 6: 2006 MHz 7: 1929 MHz 8: 1889 MHz

You find attached log files when I run:  "sudo srsue --log.all_level=info".
When I run"
sudo srsenb --log.all_level=info", the enb.log is always empty. Below the
outputs in terminals:
