The problem of connecting srsUE to srsENB
Issue Description
Hello everyone. I want, using documentation, to connect srsUE to srsENB and open5gs. Before that, I managed to connect COTS UE (One Plus 9). The phone managed to connect to the LTE network and was able to use the Internet. Now I want to connect srsUE, but I can't do it. UE detects PHY, but does not connect to the network
Technology stack
open5gs 2x Ubuntu 22.04 (Intel® Core™ i7-7700 CPU @ 3.60GHz × 8) 2x srsRAN 22.04 2x limesdr v1.4s (LimeSuite v20.10.0, SoapySDR 0.7.2)

# Analyze > Enabled Protocols > MAC-LTE > mac_lte_udp and MAC-NR > mac_nr_udp
# For more information see: https://wiki.wireshark.org/MAC-LTE

# Packet capture configuration
#
# MAC-layer packets are captured to file a the compact format decoded
# by the Wireshark. For decoding, use the UDP dissector and the UDP
# heuristic dissection. Edit the preferences (Edit > Preferences >
# Protocols > DLT_USER) for DLT_USER to add an entry for DLT=149 with
# Protocol=udp. Further, enable the heuristic dissection in UDP under:
# Analyze > Enabled Protocols > MAC-LTE > mac_lte_udp and MAC-NR > mac_nr_udp
# For more information see: https://wiki.wireshark.org/MAC-LTE
# Configuring this Wireshark preferences is needed for decoding the MAC PCAP
# files as well as for the live network capture option.
#
# Please note that this setting will by default only capture MAC
# frames on dedicated channels, and not SIB. You have to build with
# WRITE_SIB_PCAP enabled in srsenb/src/stack/mac/mac.cc if you want
# SIB to be part of the MAC pcap file.
#
# S1AP Packets are captured to file in the compact format decoded by
# the Wireshark s1ap dissector and with DLT 150.
# To use the dissector, edit the preferences for DLT_USER to
# add an entry with DLT=150, Payload Protocol=s1ap.

Interesting note. srsUE finds the cell, but then nothing happens. What should be done in this situation?
There should be a RACH attempt after it finds the cell. I dont see that in logs.
I have new logs.

I can find PLMN. But I still can't connect to the network
Sorry can#t be of much help here since I didn't try this setup. Will let you know if find anything
One thing you could try is to remove providing device_args in both UE and eNB. For the most part Soapy driver will take care of these settings
device_args = rxant=LNAH,txant=BAND1
