Hello,
I'm trying to connect a srs-ue to a srs-gnb between two computers over two USRP X410s. The cell selection completes, signal was detected on UE side, but the MIB decoding is not successful with CRC fail (SNR is pretty low)
Setup Details
The srs apps run on 2 separate machine (Dell Precision 5820 with Ubuntu 20.04),
UHD 4.4 -> USRP X410
srsRAN_4G UE: at release_23_11
srs-gnb: srsRAN_Project branch main
