I am trying to override the default DNS given by the SIM carrier, after downloading Legato R14 with framework version 18.09.02 and after some search , i found that the legato framework does not set any dns , it just read them and populate the resolv.conf in the linux subsystem.
After some experiment i managed to override the DNS that the legato framework retrieve from the connection so the DNS in the resolv.conf are always google dns.
However the cm data command always returns the SIM Carrier DNS.
Where does the CM DATA command retrive those DNS?
Going deeper i found something about PPP protocol , and an argument called “usepeerdns” but modifying this argument does not give any difference once i build the legato cwe.
