Please leave auto for gnb

Hi, you do not see any PRACH attempts in the gnb.log? Could you try if those configs work for you? https://docs.srsran.com/projects/project/en/latest/tutorials/source/srsUE/source/index.html#zeromq-based-setup

so do you want to run over ZMQ or USRP?

Are you sure those logs are from the same experment? In the UE logs, I can see the UE sent a PRACH and even got RRC connected. But I cannot...

in ZMQ-based setup, you do not need the USRP as signal samples are sent between gnb ans srsUE over a TCP sockets.

if you run the gnb and srsUE over ZMQ-RF devices, you must set the correct IPs as tx and rx endpoints. You cannot use `127.0.0.1`.

@wzh8267 any update on this issue?

in srsUE you need to correctly set the following parameters as well: ``` [rat.nr] bands = 3 dl_nr_arfcn = ... ssb_nr_arfcn = ... ... ```

just put band 1 and correct arfcn numbers
