[srslte-users] SRS UE connecting to commercial network

[Ismael Gomez]

Hi Saimanoj,

Thanks for reporting this. This is indeed a bug in resolving RV value for
Format1C for SI-RNTI. Thanks for catching that. I've pushed a new branch
with a possible fix here:
https://github.com/srsLTE/srsLTE/tree/issuefix_format1c

When you have a chance, could you please try it again and let us know if it
works? ue.log would be very useful.

Thanks
