[srslte-users] Problems attaching commercial UE to SRSENB

[Aaron Montilla]

Hi,
I am using the latest version of srsenb and an external epc. This
connection is working fine, but when I try to attach the commercial UE to
the network. The error change every time I try to connect it, but most of
the times these are the problems:
RACH:  tti=8681, preamble=13, offset=0, temp_crnti=0x46
SCHED: Could not transmit RAR within the window (RA TTI=8681, Window=10,
Now=8701)
RACH:  tti=8721, preamble=43, offset=0, temp_crnti=0x47
SCHED: Could not transmit RAR within the window (RA TTI=8721, Window=10,
Now=8740)
Disconnecting rnti=0x46.
RACH:  tti=8801, preamble=33, offset=0, temp_crnti=0x48

Some times the UE is connected but then I get these messages:

Could you help me with the problem. Any help will be appreciated.

Thank you in advance.
