# ofono/test/list-contexts
[ /ubloxqmi_0 ]
    [ /ubloxqmi_0/context1 ]
        Name = Internet
        Type = internet
        AuthenticationMethod = chap
        Settings = { Method=static Gateway=10.116.103.22 Netmask=255.255.255.25}

        Password =
        Protocol = ip
        IPv6.Settings = { }
        Active = 1

Looks like it is static, how can change it to a correct one (dynamic

There are two devices for the SARA-R4 modem, /dev/ttyUSB0 is used for
QMI which is currently using as default protocol. /dev/ttyUSB1 is for
AT, let me know if you like to check AT command, I have never tried to
write / read AT command, are the following commands correct?

echo "at+cgpaddr" > /dev/ttyUSB1
cat < /dev/ttyUSB1

Thank you very much Giacinto.
