ZMQ UE not attaching to running ZMQ gNB

[xtruhlar]

Hello @herlesupreeth,

First of all, thank you for your work, this docker_open5gs is really great piece of work.

However, I am experiencing weird problem with srsue_zmq.

Every time I try to connect to gnb, the PHY tests are done and then it stays in this state and nothing happens even after one hour.

Opening 1 channels in RF device=zmq with args=tx_port=tcp://172.22.0.34:2001,rx_port=tcp://172.22.0.37:2000,id=ue,base_srate=7.68e6

Supported RF device list: UHD soapy bladeRF zmq file
CHx base_srate=7.68e6
CHx id=ue
Current sample rate is 1.92 MHz with a base rate of 7.68 MHz (x4 decimation)
CH0 rx_port=tcp://172.22.0.37:2000
CH0 tx_port=tcp://172.22.0.34:2001
Current sample rate is 7.68 MHz with a base rate of 7.68 MHz (x1 decimation)
Current sample rate is 7.68 MHz with a base rate of 7.68 MHz (x1 decimation)
Waiting PHY to initialize ... done!
Attaching UE...

Can you help me with this?

same for me, maybe srsran setup is broken for some reason. UERANSIM works fine.

Thank you. I just now tested with master branch and I can see UE attaching

CHx base_srate=7.68e6

I am not sure why the srate is 7.68e6 it should be 23.04e6 like in my screenshot

I tried that, the PHY tests should take short time but it doesn't matter even with 23.04e6 the results are same. I build it with from dockerfile if that is what you are asking.

[herlesupreeth]

can you send me the gnb and ue logs when run with 23.04e6 on the UE?
