[srslte-users] Can't connect to commercial EnodeB with athonet

Hi again Jonathan,

I've just tried and your configuration should now be supported. So you
don't need to change the ConfigIndex. Just pull out the latest master
branch from github for srsLTE and srsUE, recompile and try again. Send the
logs again if it does not work.

Do you mind me asking what eNodeB and EPC are you currently using? We are
trying to collect a list of devices it has been tested with.

Thanks
