[srsran-users] NSA COTS UE stops broadcasting signal when adding NR Cell

Hello all!
I have a problem configuring the 5G NSA COTS UE following this guide
https://docs.srsran.com/en/latest/app_notes/source/5g_nsa_cots/source/index.html
If I *remove* the *nr_cell* section from the rr.conf file, the UE can
attach the LTE network and connects just fine. But if I *add* the *nr_cell*
to the rr.conf The UE is not even able to see the 5G NSA network in the
list of network operators.
I'm using an USRP B210 and last srsRAN version
Ubuntu 20.04.4 LTS 1th Gen Intel® Core™ i7-1165G7 @ 2.80GHz × 8
- I already have the CPU governor of the PC at performance mode
- The TX/RX LED's on both ports are not blinking
- The USRP B210 has external power supply and 2 antennas (one in TX/RX
of RF A an other in TX/RX of RF B)

I attach my current configuration and the enb log
Is it possible to generate a 5G NSA network with just a single USRP B210?
Thank you very much!!
