[srslte-users] srsUE 2x2 MIMO using USRP X310

[Andre Puschmann]

Hi Yuda,

we know of people using the X310 with 2x2 MIMO yes, although I am not
entirely sure which srsLTE version their solutions is based off.

But for your setup/issue, could you please try with the current stable
srsLTE 20.10.1 and post logs, stdout, etc. when things don't work as
expected?

Thanks
Andre
