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

Hi Jonathan,

We currently only support PRACH-ConfigIndex 0-15, that is Format0. Your
network is using Format1, ConfigIndex=19. Is it possible that you set it to
some value between 0 to 15? We could try to support other formats but we
haven't tested it yet.

Thanks
