[srslte-users] Attaching problem

[Lanfranco Zanzi]

Hi all,

we are facing some problem during the attach procedure of our USRP b210
with a commercial LTE base station. We want to try the new srsLTE release
and test it over a 2x2 MIMO setup.

As you can see from the logs attached, the procedure starts correctly, but
it does not complete due to "Timer T310 expired: Radio Link Failure".
I'm not an expert  user of srsLTE, but i do not see any issue from the
logs, except for some " Sync error. Sending out-of-sync to RRC".
The software is running on a powerful desktop PC (quad core i7 4.4Ghz), and
the basic ue.conf file has been modified only for 2 receiving antennas and
3 physical threads.

Could the out-of-sync issue be the main problem, and how can i try to fix
it?
Other devices such as mobile phone or USB dongles perfectly attach, so i
would exclude incorrect configuration in the base station.

Thank you in advance.
