LTE connection problem

[Juha Petäjäjärvi]

Hi,

we have a Conduit model MTCDTIP-LEU1-220L-868-OP (LTE mLinux) and we encountered a problem while trying to set up the LTE connection. The /var/log/messages shows that it is unable to connect ppp0 with modem_at0. Any ideas what might be wrong with the settings? Here’s some log info:
