Hi, everything was built well ( B210 SDR ), but Unfortunately, I am experiencing some issues, I pressed CtrlC after a second because it shows errors in a loop. Please advise me. ( by Cellular Z - Freq: 2630/2510MHz LTE ,Band 7FDD )

Hi, you are sniffing on a 4-port base station, which is not supported by LTESniffer. Please find a 2-port base station and try again. Thanks
