HI,

I am using srsRAN_4G version 23.11 & LimeSDR Mini 2.0, tried to run the TCP/UDP downlink & uplink throughput. DL is mostly stable but we are not getting any throughput in Uplink.

Do your SDR have a signal indicator(light) on TX/RX ANT？MY b210 has the same problem and when I set 75, my lights will flash instead of stable at"work",I guess it's about hardware support.
