Hi everyone, I am totally to srsLTE.
I am using two computers Ubuntu 16.04 with B210 and Ubuntun 18.04 with
bladeRF.
Here below are the outputs for srsepc, srsenb and srsue,

Additonal Information:
Is it necessary to install for both computers to use UHD LTS 3.9.0
version?
This command was run on the ubtunu 18.04 with the bladeRF, I would to
ask if it the model of the bladeRF I am using is x115? I also using
wanna know how to rectify PDSCH-BLER, it looks there is a lot of
errors. I apologise for the handful of questions but I stuck at the
moment. Hope anyone can advise me with the steps to approach this
question, with commands will be much clearer for me. Thanks in advance :)
