[srslte-users] Problem running example with B210

Hello.

I am Robson, I am a undergraduate student and have no experience in this
area and need to use srsLTE for my internship.
I have been trying to run the pdsch_enobeb and pdsch_ue examples from
srsLTE without success.
I can see the transmitter in the spectrum analyzer, but the receiver seems
to not receive the data.
The frequency used is 2480MHz and the radios are USRP B210.
The computers are two ubuntu i7 laptops.
The command at the transmitter is :

./pdsch_enodeb -f 2480000000

At the receiver:

./pdsch_ue -f 2480000000 -r 1234

I also have tried different gains for receiver and transmitter.
The antennas used are recommended for this frequency.
Transmitter and receiver were swapped, but the output was the same.
The program outputs at the receiver and transmitter are attached.

I would be very grateful for any help.
Best regards.
Robson Couto.
