e320 Tx while waiting for EOB, timed out...

Issue Description

Hello all, I am trying to run my x300 as a 5G gNB with srsRAN Project and my e320 as a UE with srsRAN 4G. I followed the tutorial on the documentation page and the X300 starts the gNB with no errors. It also displays a solid red light with no flashing; so I assume it's working.

However, when I start srsUE, my e320's LED constantly flashes and I receive a lot of Tx EOB errors. It naturally doesn't connect to the gNB. Is the e320 supported? Or am I just not configuring it correctly (most likely the latter)?

Setup Details

Asus ROG Laptop (i9-8950HK, 2.5gbe, nvidia rtx 2080 mobile) UHD 4.3.0-HEAD-0-g1f8fd345 Rocky Linux 8.7 Ettus E320 and Ettus X300

Expected Behavior

e320 UE connects to X300 gNB

Actual Behaviour

This is the output I am receiving from the srsUE

mgmt_addr=192.168.10.3,type=e3xx,product=e320,fpga=1G,claimed=False,addr=192.168.10.3 [INFO] [MPM.PeriphManager] init() called with device args `fpga=1G,mgmt_addr=192.168.10.3,name=ni-e320-325EA60,product=e320'.

Steps to reproduce the problem

I followed the online tutorial srsRAN gNB with srsUE. I then started the srsRAN gNB with the X300. It connects to my open5gs core, with the number of gNBs becoming 1. and I receive the following line like in the tutorial: Cell pci=1, bw=10 MHz, dl_arfcn=368500 (n3), dl_freq=1842.5 MHz, dl_ssb_arfcn=368410, ul_freq=1747.5 MHz

I then start the srsRAN UE with the e320 and receive the tx EOB info warnings.

Additional Information

The e320 is started with type=e3xx, sampling_rate=11.52e6, lo_freq_offset_hz=11.52e6, addr=192.168.10.3

I'm having the same problem with the x310. As far as I know, your sampling_rate and lo_freq_offset_hz param should be 23.04e6 while the [rf] srate param should be 11.52e6. You'll start to get "Random Access Transmission..." messages in the ue console. srsue.log will show consistent sample misalignment errors.

Change the sampling rates and see how it performs.
