srsran5g-simulated-rf: Updated SRS Hash

[praghur]

Hi Dustin & POWDER community.

I am running the srsran5g experiment after updating to the latest SRS hash from the profile - https://www.powderwireless.net/show-profile.php?project=PowderProfiles&profile=srsran5g-simulated-rf.

DEFAULT_SRS_HASHES = {
    "srsRAN_4G": "release_23_11",
    "srsRAN_Project": "release_24_04",
}

I made changes to the config files of ue and gnb as shown in the attachment as per the srsran documentation-https://docs.srsran.com/projects/project/en/latest/tutorials/source/srsUE/source/index.html#zeromq-based-setup

However, my UE receives an "RRC Release" within a few seconds of RRC connected status. The AMF logs are pasted below.

Has anyone encountered this before? Is there a way to get around it?

Looks like a DNN/APN mismatch. UE has srsapn… maybe the entries in your AMF database are internet? If so, just update the UE config to reflect that.
