[srslte-users] Attaching problem

[Andre Puschmann]

Hi,

there seems to be an issue with receiving from the USRP as well, see
logs for overflow warning.

Have you tried what Ismael suggested a few days ago to Andres? Also, if
you have the possibility, you could try to reduce the bandwidth of the
cell to 15 or 10 MHz to lower the processing load for the UE.

Cheers
Andre
