Having trouble connecting and getting an IP address after connecting srsRAN, gNB, and srsUE using ZMQ

[aayamrajshakya]

ue_zmq.conf.txt
ue.log

mme.log
gnb_zmq.yaml.txt
gnb.log
amf.yaml.txt
amf.log

We tried changing the config files according to the documentation. We still have trouble getting an IP address assigned to the UE. Any ideas where we are messing up? Thank You.

did you create a network namespace for the ue?

sudo ip netns add ue1

[aayamrajshakya]

Yes, i did it

It seems that AMF does not accept the UE, check the logs:

@aayamrajshakya any update on this issue?

[aayamrajshakya]

Good morning, Mr. Piotr. Sorry for the late reply, I have been occupied with classworks lately. Yes, I finally figured out the issue; we just missed configuring the nrf.yaml

[pgawlowicz]

great! thanks for your feedback!
