[srslte-users] New install, RRC_IDLE and Detected Radio-Link Failure

[Teng Fei]

Dear all,

We are trying to connect srsue to an Amarisoft cell. After doing the basic
installation,when we run the srsue we got the following messages,


------------------------------------------------------------
---------------------------------------------------------------------------
Searching cell in DL EARFCN=3350, f_dl=2680.0 MHz, f_ul=2560.0 MHz

Meanwhile, there is no new interface in 'ifconfig' and we can not ping the
Amarisoft cell.

And We have also read through the previous posts, and here are what we have
done,
1.Make sure the cpu power mode is 'performance'.
2.Increase the tx_gain of srsue.
3.Run as root user.
4.Input the ismi,opc,etc into the Amarisoft config file.

Here is what we are using for srsue
usrp x310 release 3.10.0.0
A desktop which the cpu is Intel® Core™ i7-6700 CPU @ 3.40GHz × 4

Could anyone help us out please? Thanks in advance.

Ps. we also attach  the ue.log and ue.pcap.

Best wishes,

Teng
