I installed srsRAN-4G on an Ubuntu 22.04 desktop and use low latency kernel:
$ uname -r
5.15.0-79-lowlatency.
epc run correctly:
~/srsRAN_4G/srsepc/src$ sudo srsepc

Hello. Thanks for your attention. My problem is solved by changing the simcards. I bought OYEITMES simcards and their writer.

Seems that both srsepc and srsenb cannot find config files.
You need to pass proper config files to both of them.
In addition, you can execute this script to optimise the host PC:

Could you try with srsUE with default configs to see whether it can connect?

Hello. my
When the GPS is locked and the SIM card can find the APN, in addition to having the UL NAS: Authentication Failure
, after a while this error also occurs in enb and it deth completely.
ERROR] [STREAMER] The receive packet handler caught a value exception.
ValueError: bad vrt header or packet fragment

I set these to enb.conf:

device_args = type=b200,clock=gpsdo,otw_format=sc12

The streamer errors come from UHD driver. Hmm, we always run with uhd 3.15 or 4.3. Could you try that? Please remember to recompile srs project after reinstalling UHD version
