[srslte-users] UE not identifying ENB

[devifr]

No go on either of the resource block configs.  I'll send the logs/pcaps
separately. They exceed the max size .

A couple of items that I notice in both of the epc logs is that 1) both the
HSS and MME identify the MCC/MNC as 61441/65281 and 2) it indicates that
IPv6 is not supported.  To address the first item, the PLMN in both the
enb.conf and the epc.conf indicate a MCC/MNC of 00101.  To address the
second item, I've confirmed in the APN settings that it is set to IPv4.
I'm not sure where either of the previously mentioned errors are coming
from.

Additionally, I've attached a screenshot of my SIM parameters.  This is
just to ensure that I've got everything correct.  Also, I've tried this SIM
in an Essential device....no joy.

Any input is greatly appreciated.
