Am using the srsRAN gNB and UE, and open5gs core to perform Initial Registration procedure. I could see the NGAP packets and not able to see RRC packet. Is there any process to decode the RRC packet?

Please let me know, Thanks in advance

Are the RRC packets sent across ZeroMQ sockets? If so, there is now a zmtp dissector in the developer branch. It's preferences can let you define which TCP ports are Zmtp, and potentially to associate a dissector for the payload data for each port number. I have no idea how the Rrc PDUs will be framed, but would be interested to see a capture if you are able to share. Also note that just setting nr-rrc will not work - there is effectively a different entry point for each channel type / direction...

If you are able to share a capture, the best idea might be to attach it to a new issue at https://gitlab.com/wireshark/wireshar...
