Hello,
I use srsUE running on i7 notebook with USRP B210 (two antennas) as UE and
OpenLTE running on i7 notebook with USRP B210 as eNB (two antennas).

OpenLTE configuration is:
band = 3
bandwidth =5
dl_earfcn =1375
mcc =001
mnc =01
tx_gain =86
rx_gain =30
debug_level =rrc
debug_type=warning info debug
enable_pcap=1
other config - default

srsLTE configuration is:
dl_freq = 1822500000
ul_freq = 1727500000
...
[pcap]
enable_pcap = 1
...
other config is as in example file "ue.conf.example"

1. First, i try to connect UE with operator's sim to eNB and get such log
in terminal at 30001 port of eNB
01/02/2016 00:10:52.210251 info rrc LTE_fdd_enb_rrc.cc 237 Received PDU for

So I supposed eNb is OK!

2. Then i start UE: sudo ./ue ue.conf and
Searching for cell...

and that all,..
I open ue.pcap file in wireshark with mac-lte-framed dissector but there
are only strange RRCConnectionReestablishment messages, and there are NO
RRC messages in terminal at 30001 port of eNB
I attached ue.pcap and ue.log.
Can you help me with this problem?
Thank you.
