[srsran-users] 5G SA Connection Issues with 22.04.1

[Robert Falkenberg]

Hi Joe,

there has been a change related to CoreSet0 index 
<https://docs.srsran.com/en/latest/app_notes/source/5g_sa_COTS/source/index.html?highlight=coreset0_idx#fdd-bands> 
in srsRAN 22.04.1.
Try to set |coreset0_idx| in your |rr.conf|, e.g. as in this example 
<https://docs.srsran.com/en/latest/app_notes/source/5g_sa_COTS/source/index.html?highlight=coreset0_idx#rr-conf>.

Best regards,
Robert
