Dear srsLTE
i ran srsue in a machine , ran eNB and EPC in another machine. A limeSDR
USB is used in every machine as RF end. on the ue machine, i just use srsue
without usim card. I think it will use the user info in the ue.conf, such
as IMSI.
i change some items in ue.conf : apn_protocol =ipv4. And i also set CPU
scaling disabled on the ue machine. but i can see that the ue has attached
the network sucessfully. After 1 minutes it tries to re connect to the
netwrok. Then it releases from the network.
the two machine is near. the distance of two limesdrs is within 15cm.
from trace on enb terminal, i saw DL snr from 15db to 0db .
