1 year ago It seems that the frequencies used by the two stations are different:

You can try by playing around with the parameters: dl_nr_arfcn and ssb_nr_arfcn in the [rat.nr] section of ue.conf and the parameters: dl_arfcn and ul_arfcn in rr.conf

Issue Description
Hello, I have been trying to connect srsUE to srsENB between two computers using two USRP X310s. Despite confirming that the USRPs can see the signals using the UHD test waveform and RX DFT examples, I have not been successful in getting the srsRAN software to communicate.
Setup Details
Two Ubuntu host PCs running Ubuntu 20.04 inside VirtualBox with bridged adapters so that they act as separate devices on the network. These PCs are not connected to any network besides their connection with the USRP RF hardware. srsRAN 22.04.1 is being used with a USRP X310 on each computer containing a single UBX-160 daughterboard each with two antennas attached to each daughterboard. UHD 4.2.0 is being used on both computers and the 1Gbit interface is being used, not 10Gbit.
Expected Behavior
The UE connects to the base station and I am given an IP address for the UE. I should be able to ping the computers from both sides.
Actual Behavior
The UE tries to find a cell and attach to the base station, but fails to do so. Using the
rx_ascii_art_dftscript shows that the USRP X310 attached to the UE is able to receive the signal at ~1800MHz (NR band 3) from srsENB. Sometimes the RF times out, but regardless of whether it does or not, the same behavior occurs.Steps to reproduce the problem
Follow the instructions here but instead of using ZeroMQ, change the configuration to use UHD driver with the following device arguments:
device_args = type=x300,clock=internal,sampling_rate=11.52e6,lo_freq_offset_hz=23.04e6,send_frame_size=1472,recv_frame_size=1472,num_send_frames=64,num_recv_frames=64,NoneAdditional Information
The logs from the srsENB and srsUE commands are attached. We have also tried using srsRAN’s
cell_searchtool but it freezes after the first 50 iterations or so. srsENB shows RF underflow and srsUE shows RF overflow, if that is relevant. The Open5GS core connects to srsENB with no issues, and the UE configuration inue.confmatches the configuration entered into the Open5GS frontend.srsgnb3.log srsue3.log
