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 :)
