Issue Description

Cell and PLMN cannot be found when using srsUE

Setup Details

[ue] Ubunt22.04 USRPb210

[enb,epc] Ubunt22.04 BladRFA115

Expected Behavior

I expect to get the following result when I execute srsue ue.conf.example image

Actual Behaviour

When I executed "srsue ue.conf", the following problem occurred `root@autohack-virtual-machine:/home/autohack/srsLTE/srsue# srsue ue.conf Active RF plugins: libsrsran_rf_uhd.so libsrsran_rf_soapy.so libsrsran_rf_blade.so libsrsran_rf_zmq.so Inactive RF plugins: Reading configuration file ue.conf...

Steps to reproduce the problem

Additional Information

I have had results for RF status: O=0, U=0, L=0 and O=1, U=0, L=0

I thought UE was to be run last, after e/gnb and epc. Your screenshot is different from your supplied text - it seems like the bladeRF drivers work fine.

The developers suggest using UHD 4.1 or 3.15, so try to revert back to those versions (git checkout...) for the ue. Those lines occur with overflow errors - try using ./benchmark_rate --rx_rate 11.52e6 --tx_rate 11.52e6 to see if your UHD version correctly works with the b210.
