Chandana,
Based on that I think you have a connection issue, not a MQTT issue. Can
you ping the LWIP system from the outside when it's up? You should be
able to if you have not deliberately blocked it. I assume the IP
addresses and routing is all taken care of but I suggest to check it in
any case.
To answer your question in the other e-mail: the callback will be called
when the connection attempt finished, whether successful or not.
Regards,
Eric.

Eric,
My Mosquitto broker is working fine on the system, publish and
subscribe have been verified.
But on using the mqtt connect function of lwip and analysing the
packets, I observe that there are no MQTT request packets that are
being sent from the system.
I have also verified the same with another MQTT code which was taken
from the lwip examples. That has also failed.
Do the functions of lwip work ? Or are there any extra configurations
to be made ?
Regards,
Chandana.
